7 Executive Summary As traffic volumes and their associated problems (congestion, delay, increased travel time, reduced travel time reliability, etc.) continue to grow throughout the state, it is increasingly becoming apparent that we are unable to build ourselves out of these issues. Adding more lanes to the existing roadway network is often not a viable option given right-of-way and other cost constraints. A much more cost efficient and viable alternative is maximizing the operational efficiency and management of the existing roadway infrastructure through the use of Intelligent Transportation Systems (ITS) and devices. The (CDOT) has invested significant resources in the deployment of Intelligent Transportation System (ITS) infrastructure in Region 6 including numerous ITS devices such as: fiber optic cable on I-70 and I-25, Travel Time Indicators (TTI), Closed Circuit Television (CCTV) cameras, Highway Advisory Radio (HAR), Road and Weather Information Service (RWIS) and Variable Message Signs (VMS). CDOT Region 6 intends to continue this ITS investment in the future given the mobility and safety benefits derived from actively managing the transportation system. CDOT Region 6 is unique, in respect to other CDOT Regions, due to the numerous urban signalized arterial and freeway corridors contained in the Region. This results in an ITS vision that is also somewhat unique; To ensure arterial and freeway ITS infrastructure and applications are deployed and operated in an integrated manner in order to maximize efficiencies and leverage benefits of the transportation network. This regional vision was developed with the following strategies in mind: Strive to implement ITS deployments that can provide benefits for both freeway and arterial corridors and commuters Increase communication backbone/infrastructure coverage and reliability to support wider ITS deployment Increase traffic and incident management capabilities throughout the region on freeway and arterial corridors Increase coordination, access and sharing of corridor data and resources both within CDOT as well as with regional partners outside of CDOT The integrated operation of freeway and arterial ITS infrastructure is an acknowledgement of the synergies that exist between these two types of corridors in the region. For example, an incident along I-25 often causes severe congestion along major arterials that provide an alternative route around the incident. It is hoped that through the concentrated deployment of integrated ITS devices such as Arterial Travel Time Indicators (TTI) and Variable Message Signs (VMS), that much of the traffic that would be diverted off I-25, in the case of an incident, can be diverted to alternative routes long before reaching the highway. This directly benefits everyday commuters by reducing congestion, delay and driver frustration. The benefits of any single ITS device are often difficult to quantify individually, however the benefits become more quantifiable within the context of the application, i.e. (traveler information, Traffic Responsive Signal operations, traffic and incident management), as the many elements of the system are integrated. This integration empowers CDOT i

8 Executive Summary operators to positively impact current travel conditions, react quickly to incidents and congestion along corridors, assist in modifying travel plans based on current roadway conditions, and disseminate real-time traveler information. In general, CDOT s goal in deploying ITS technologies is to improve the productivity of the transportation system and to provide services that enhance and improve the mobility and safety of Colorado s traveling public. Tangible benefits on both regional and national levels have been realized as a result of the deployment of ITS devices and the benefits to cost ratios of these deployments are typically very high. Detailed benefits documentation of existing ITS deployments are outlined in the main body report. To ensure that these ITS resources are effectively and efficiently deployed across multiple jurisdictions and agencies, several ITS planning documents have been developed for Region 6. These documents include: 1. CDOT Statewide ITS Strategic Plan 2. Denver Regional Council of Governments (DRCOG) ITS Strategic Plan/Architecture 3. Region 6 Five-Year Communication Plan 4. Region 6 ITS Maintenance and Operations Plan 5. Region 6 Fiber Map 6. Region 6 Ramp Metering Study 7. CDOT Incident Management Plan (IMP) ITS Recommendations for US-6, US-36, I-25 TREX, I-25 North and Northwest Parkway These ITS planning documents provide the framework and long-range vision for the implementation of ITS applications in Colorado and Region 6. The realization of the objectives for Intelligent Transportation Systems in Colorado and CDOT s Region 6 is dependent upon developing specific projects to deploy the enabling infrastructure 1 and establish the communication and coordination linkage that do not yet fully exist. The purpose of this Region 6 ITS Implementation Plan is to consolidate all ITS projects for Region 6 into a single document that will enable Region 6 staff (engineers, planners, designers, maintenance personnel, etc.) to manage the planning, programming and deployment of individual ITS projects. This Region 6 ITS Implementation Plan contains all known ITS deployments and/or projects on corridors of significance from the previously mentioned ITS planning documents. This Plan consolidates ITS deployments and/or projects on thirty two (32) corridors of significance in an organized and efficient manner specifically for Region 6. This includes nine (9) deployments on freeways and eighty four (84) projects on arterials. 1 As identified in the Statewide ITS Strategic Plan, the enabling infrastructure consists of integrating the CTMC and other major TMCs, deployment of fiber-optic backbone and high speed add/drop multiplexers and connection of existing and deployed devices to the fiber optic backbone. ii

9 Executive Summary For clarification, implementation of ITS devices on individual freeways are grouped on a device by device deployment basis, but are not prioritized. Arterial ITS implementations are grouped at the project level. Many arterials have been segmented and are identified for multiple projects. Not all Region 6 arterial corridors of significance currently have ITS projects planned, however all Region 6 arterial corridors of significance have been included in this Plan to facilitate the future development of ITS projects on those corridors. In addition, it should be noted that all ITS projects that have federal funding must be developed using Systems Engineering Analysis (SEA) process. CDOT has developed SEA guidelines to be used in conjunction with ITS Regional Architectures regarding project implementation. More information regarding the SEA process is provided in Section 1. It should be noted that the newly updated DRCOG ITS Strategic Plan does not identify specific projects for deployment and instead uses Transportation Service Areas for guidance on implementing projects. Regardless, all of the Region 6 projects identified in this plan that are in the DRCOG area are consistent with Regional needs and the DRCOG ITS Strategic Plan. For purposes of this Plan, all ITS deployments and/or projects for each corridor were considered aggregately in conjunction with the Region s overall vision of ITS services to be provided on the corridor in order to determine appropriate implementation timeframes. Although the plan recommends implementation timeframes, it should be noted that projects can be accelerated or temporarily delayed based on synergies that exist during the decision making process. This allows Region 6 the necessary flexibility to leverage resources and save CDOT implementation costs in the long term. Tables ES-1 through ES-4 show the needed investment (estimated construction costs) for CDOT Region 6 ITS projects in 2009 dollars (estimates are not indexed). These construction cost estimates also include estimated costs for network equipment necessary for system connectivity; however, they do not include operations and maintenance costs. Table ES-1 shows the needed investment for CDOT Region 6 ITS freeway deployments. Freeway ITS deployments do not have a specific priority associated with them. Table ES-1: Region 6 Freeway Needed ITS Investment Summary Freeway Corridors Number of Freeway Corridors 9 Needed Investment (In $Millions) Table ES-2 shows the needed investment for the 84 identified CDOT Region 6 ITS arterial projects. Arterial projects are ranked as high, medium or low priority and are further prioritized on a project by project basis. iii

These are projects that are not tied specifically to a geographic location but affect the entire region. Examples of regional projects include: Transportation Operation Centers CTMC Support of Region 6 Traffic Operations during after-hours and weekends Development of Region 6 ITS Communication Plan Infrastructure to provide connectivity to other agencies in the Region Table ES-3: Region 6 Regional Needed ITS Investment Summary Regional s High Priority Medium Priority Low Priority Total Number of s Needed Investment (In $Millions) s Table ES-4 shows the summary of needed ITS investment for Region 6. Table ES-4: Region 6 Total Needed ITS Investment Summary Needed Investment (In Millions) Freeway Corridors $62.18 Arterial Corridors $40.14 Regional s $9.27 Total $ With a total funding need in excess of $100 million dollars and given budget constraints and limited revenues for the foreseeable future, it is unrealistic to expect that all ITS projects will be able to be implemented within the timeframes identified in the Plan. Based on this, a preferable strategy would be to include the ITS projects as part of any planning, design, and construction projects along corridors to maximize ITS implementation and leverage the construction project funding. As any corridor project is being developed, there is an opportunity to implement ITS projects and realize cost iv

11 saving synergies. For example, the inclusion of an ITS project with a corridor overlay project can result in potential cost savings of 15 to 50 percent. This is due to the typical overlay project requirements of lane closures, alternative routings, traffic control, and construction and project engineering cost requirements that often must be duplicated in many stands alone ITS projects. Ultimately, this will not only cut costs and allow for quicker deployment of ITS devices, but will also accelerate operational improvements and efficiencies that directly benefit the traveling public. v

12 I. Introduction Background The (CDOT) has invested significant resources in the deployment of Intelligent Transportation System (ITS) infrastructure in Region 6 including numerous ITS devices such as: fiber optic cable on I-70 and I-25, Travel Time Indicators (TTI), Closed Circuit Television (CCTV) cameras, Highway Advisory Radio (HAR), Road and Weather Information Service (RWIS) and Variable Message Signs (VMS). CDOT Region 6 intends to continue this ITS investment in the future given the mobility and safety benefits derived from actively managing the transportation system. The Region 6 ITS Implementation Plan covers the entire geographical area for the s (CDOT) Engineering Region 6. Figure 2 (Page 9) depicts the geographic boundaries associated with Region 6 ITS Implementation Plan, which is consistent with the area of responsibility for CDOT s Engineering Region 6. Figure 3 (Page 10) shows the existing ITS infrastructure in CDOT Region 6. Several Intelligent Transportation System (ITS) planning documents have been developed to date for Colorado that includes portions or all of CDOT s Region 6. These documents were created in order to define the strategic direction and long-range vision for the deployment of ITS in Colorado, develop a framework for ITS implementation that facilitates multi-jurisdictional coordination and ensure conformance with 23 CFR Part 940. These planning documents include: 1. CDOT Statewide ITS Strategic Plan 2. Denver Regional Council of Governments (DRCOG) ITS Strategic Plan/Architecture 3. Region 6 Five-Year Communication Plan 4. Region 6 ITS Maintenance and Operations Plan 5. Region 6 Fiber Map 6. Region 6 Ramp Metering Study 7. CDOT Incident Management Plan ITS Recommendations (US-6, US-36, I-25 TREX, I-25 North and Northwest Parkway) Purpose of the Document CDOT Region 6 is unique, in respect to other CDOT Regions, due to the numerous urban signalized arterial and freeway corridors contained in the Region. This results in a ITS vision that is also somewhat unique; To ensure arterial and freeway ITS infrastructure and applications are deployed and operated in an integrated manner in order to maximize efficiencies and leverage benefits of the transportation network. This regional vision was developed with the following strategies in mind: Strive to implement ITS deployments that can provide benefits for both freeway and arterial corridors and commuters 1

13 Increase communication backbone/infrastructure coverage and reliability to support wider ITS deployment Increase traffic and incident management capabilities throughout the region on freeway and arterial corridors Increase coordination, access and sharing of corridor data and resources both within CDOT as well as with regional partners outside of CDOT The integrated operation of freeway and arterial ITS infrastructure is an acknowledgement of the synergies that exist between these two types of corridors in the region. For example, an incident along I-25 often causes severe congestion along major arterials that provide an alternative route around the incident. It is hoped that through the concentrated deployment of integrated ITS devices such as Arterial Travel Time Indicators (TTI) and Variable Message Signs (VMS), that much of the traffic that would be diverted off I-25, in the case of an incident, can be diverted to alternative routes long before reaching the highway. This directly benefits everyday commuters by reducing congestion, delay and driver frustration. The objective of this Region 6 ITS Implementation Plan is to develop a single document that Region 6 staff can utilize to effectively manage specific ITS deployments within Region 6. This Plan will enable Region 6 staff to champion the implementation of ITS in Region 6 and facilitate the planning, programming and design of individual ITS projects that will establish the ITS infrastructure required to fulfill the ITS vision for Region 6. This Plan consolidates all ITS deployments from the planning documents identified above into a single document that categorizes the specific deployments within their respective corridors of significance, i.e., freeways and arterial corridors. Implementation of ITS devices on individual Freeways are grouped on a device by device deployment basis, but are not prioritized. Arterial ITS implementations are grouped at the project level. Many arterials have been segmented and are identified for multiple projects. Not all Region 6 arterial corridors of significance currently have ITS projects planned, however all Region 6 arterial corridors of significance have been included in this Plan to facilitate the future development of ITS projects on those corridors. As the transportation needs of Region 6 change over time and individual ITS projects are implemented, this Plan should be updated to reflect the current status of the Region 6 ITS program. Revisions can and should include the modification of existing and the addition of new ITS deployments or projects, changes in priority and sequencing of projects and modification and/or addition of corridors, as appropriate. This Plan does not supersede or replace any of the existing ITS planning documents, but rather establishes an ITS planning tool specifically for Region 6. The other ITS planning documents contain valuable information regarding the deployment of ITS. This Plan is specifically targeted for Region 6 utilization, however, and only contains information relevant to ITS implementation in Region 6. The other ITS planning documents should continue to be referenced by the Region 6 staff to ensure that the ITS projects mentioned in subsequent sections are deployed in a manner consistent with multijurisdictional objectives. For example, Region 6 ITS projects that are also within the DRCOG area should be implemented in conformance with the DRCOG ITS Architecture to ensure multi-agency communication and coordination is achieved and device interoperability and jurisdictional coordination is facilitated. 2

14 An Architecture database has been created using Turbo Architecture version 4.1 for the DRCOG ITS Architecture. Turbo Architecture is a software tool that allows users to catalogue and organize regional and/or project architectures in a database format. The software also provides users with enhanced functionality in working with architecture stakeholders, elements, market packages, operational concepts, functional requirements, interfaces, standards and agreements. The software defines the architecture, relationships, interconnects between stakeholders and elements and gives the user the ability to access physical and logical diagrams at multiple levels. Use of the software will facilitate consistency, version control, maintenance and subsequent updating of the Regional Architecture. It will also be useful in obtaining and providing project Architecture related information as is required by, and in order to comply with, FHWA Systems Engineering Analysis. FHWA Systems Engineering Analysis In order to meet the requirements of 23 CFR Part 940 to receive federal funding, an ITS project must demonstrate that a systems engineering analysis was performed during the design of the project. The systems engineering analysis process includes the following seven elements that must be addressed to ensure a project conforms to the federal ITS requirements: 1. Description of how project fits into the Regional ITS Architecture 2. Roles and responsibilities of participating agencies 3. Requirements definition 4. Analysis of alternative system configurations and technology options 5. Procurement options 6. Applicable ITS standards and testing procedures 7. Procedures and resources necessary for operations and management of the system CDOT and DRCOG developed Systems Engineering Analysis (SEA) Guidelines that describe the method of demonstrating compliance with the federal ITS requirements. The requirement for SEA only applies to those ITS projects that have federal funding; however CDOT and DRCOG believe that there is value in requiring all ITS projects to use the SEA in order to ensure architectural consistency and integrity. Again, the Turbo Architecture databases will be very useful in obtaining and providing much of the project Architecture related information required in order to comply with the systems engineering analysis. FHWA or FTA may independently request additional documentation on the systems engineering analysis before federal funds are released for construction. The SEA Guidelines, DRCOG ITS Architecture, and the Turbo Database are all available at the following ITS website: URL: Username: Password: Monroe\ITS_Working_Group Int_Trans_Sys*924 3

Benefits of CDOT ITS Deployments The (CDOT) Region 6, has an extensive deployment of Intelligent Transportation System (ITS) technology throughout the greater Denver metropolitan region. This enables CDOT operators to optimize the capacity of the existing roadway infrastructure through various activities such as: Monitoring roadway conditions through Closed Circuit Television Cameras (CCTV) Monitoring weather conditions through local weather station equipment Updating Variable Message Signs (VMS) to inform motorists of incidents and congestion Dispatching Courtesy Patrol Drivers to respond to stranded drivers and minor incidents Updating their COTRIP web site to help drivers plan trips Adjusting Ramp Meters to improve freeway operations Electronic toll collection to reduce corridor travel time and delay on HOV/HOT lanes Traffic Responsive Signal Control to dynamically change signal operations in response to real time demands Monitoring Traffic Signal daily operations (i.e., signal in flash, signal running free, running the correct plan, checking detection operation), and the ability to respond to incidents in a timely manor by adjusting timings remotely The benefits of any single ITS device are often difficult to quantify individually, however the benefits become more quantifiable within the context of the application, i.e. (traveler information, Traffic Responsive Signal Control, traffic and incident management), as the many elements of the system are integrated. This integration empowers CDOT operators to positively impact current travel conditions, react quickly to incidents and congestion along corridors, assist in modifying travel plans based on current roadway conditions, and disseminate real-time traveler information. In general CDOT s goal in deploying ITS technologies is to improve the productivity of the transportation system and to provide services that enhance and improve the mobility and safety of Colorado s traveling public. The following are some examples that demonstrate the benefits of ITS locally and/or nationally. Traffic Signal Timing and Traffic Responsive Operations Through ITS system detection and fiber optic communication infrastructure Region 6 traffic engineers are able to coordinate and maintain progression along adjacent signals of a corridor. This ITS infrastructure also allows for the collection of traffic data (speed, volume, and occupancy) empowering Traffic Responsive signal operations that adjust signal timing to existing conditions. Overall, the increased reliability in signal timing operations, due to ITS, allow for the most efficient utilization of the existing roadway. Shown in Table 1 are arterial corridor benefits on SH-121/US-287 associated with a corridor retiming project. These are typical results that can be expected along any metro 4

16 Denver signalized arterial corridor of comparable average daily traffic volume (ADT) and illustrate the importance of reliability of communication infrastructure as provided by ITS investments. Table 1: 2008 Signal Timing Benefits along SH-121/US-287 Wadsworth Pkwy. Performance Measures Daily Benefits Vehicle hours of travel 620 hours reduction Fuel consumption 1,720 gallons decrease Time and fuel costs $16,150 Savings Total pollutant emissions 704 pounds reduction Average Daily Traffic Volume 40,0000 Source: March 2009 SH-121/US287 DRCOG Signal Timing Brief Ramp Metering CDOT R6 has over 70 ramp metering sites In December 2003, CDOT R6 implemented ramp metering on I-25 southbound between 104 th Avenue and 84 th Avenue and C-470 westbound between Bowles and Quincy Avenue. Initially the ramp meters were in operation during the morning peak period (6-8:30 a.m.). Prior to the implementation of these ramp meters, CDOT ITS Branch and CDOT Region 6 conducted before conditions studies on the two corridors. After conditions studies were conducted during late January Figure 1 shows the benefits noted in the comparison of before and after conditions studies. Figure 1: CDOT Region 6 Ramp Metering Benefits (I-25 and C-470) 5

17 A study conducted in Minneapolis Minnesota further reinforces the benefits of ramp meters. This study was conducted after public questioning of the use of ramp metering and a legislative mandate requiring MNDOT to study the effectiveness of ramp meters. MNDOT conducted the study by comparing before and after conditions for with and without ramp meters scenarios. The following findings resulted from the study: Traffic Volumes and Throughput: After the meters were turned off, there was an average nine percent traffic volume reduction on freeways and no significant traffic volume change on parallel arterials included in the study. Also, during peak traffic conditions, freeway mainline throughput declined by an average of 14 percent in the without meters conditions. Travel Time Reliability: Without ramp metering, freeway travel time is almost twice as unpredictable as with ramp metering. The ramp metering system produced an annual reduction of 2.6 million hours of unexpected delay. Benefit/Cost Analysis: Ramp metering results in annual savings of approximately $40 million to the Twin Cities traveling public. The benefits of ramp metering outweigh the costs by a significant margin and result in a net benefit of $32 to $37 million per year. Courtesy Patrol CDOT R6 currently provides courtesy patrol over 80 miles of highway Beginning in 1992, CDOT Region 6 implemented the Mile High Courtesy Patrol (MHCP) service in the Denver Metro area on multiple segments of highways. In a study conducted for 2003 MHCP operations it was determined that MHCP assisted in over 6,000 incidents, based on CTMC Dispatch data. This amounted to a yearly estimated benefit of: Over 500,000 hours of vehicle delay averted Over $9 Million dollar savings from reduced delay Variable Message Signs CDOT R6 has over 56 VMS signs deployed In general, it is difficult to measure the stand-alone benefits of Variable Message Signs. However, the benefits regarding the use of VMS are very high when used in conjunction with other systems. These benefits include dissemination of real-time travel time and highway conditions information (incidents, events and other related corridor information), to which allow drivers to make informed decisions regarding selection of alternative routes as well as reducing driver related stress and the occurrence of secondary crashes. Real-Time Travel Time Applications CDOT currently utilizes Travel Time Applications along I-70 Through the use of real-time travel time applications, the dissemination of real time corridor performance (travel times, delay, congestion) empowers motorists with information that allows them to modify their travel routes and times. Travel time applications are envisioned for freeway corridors throughout Region 6. It is anticipated 6

18 that for a typical freeway corridor (carrying approximately 100,000 vehicles/year) realizing a 3 minute weekly reduction in travel times, the resulting savings would be: Approximately 120,000 gallons/year in fuel consumption reduction Approximately 300,000 lbs/year in CO reductions Traffic Management and Traffic Operation Centers (TMCs & TOCs) Through the use of Intelligent Transportation System (ITS) devices, TMCs and TOCs gather real time roadway condition information for decision making to improve overall traffic flow and aid in reducing congestion. By acting as a focal point for traffic information, the TMC and TOC permit engineers to more effectively use existing traffic management tools and provide a platform for the implementation of future technological advances in traffic management. The ability of local and regional TMCs and TOCs to communicate between each other is also key to regional cooperation, sharing of information and management of cross-jurisdictional congestion and incident management. The TMC and TOC are a tool for reducing congestion and managing incidents that directly benefits motorists. Incident and Event Management Plans Incident and event management plans yield significant benefits through reduced vehicle delays and enhanced safety to motorists through the reduction of incident frequency, improved coordination, response and clearance times in response to incidents and large events. CDOT currently has coordinated Incident Management Operations ongoing at the Colorado Traffic Management Center (CTMC), Eisenhower-Johnson Memorial Tunnel (EJMT), Hanging Lakes Tunnel (HLT), and Colorado Springs Traffic Management Center (CSTMC) facilities. CDOT Region 6 Incident Management Activities are coordinated as part of the CTMC operations in conjunction with local jurisdictions Traffic Operation Centers (TOCs); i.e, the cities of Denver, Lakewood and Aurora. Within Region 6 Incident Management Plans (IMP) can be implemented and managed from the CTMC for the following corridors: I-25 freeway corridor (TREX) I-25 North I-70 US-6 US-36 Northwest Corridor Although no incident management benefit studies have been conducted for Region 6 IMP activities, it is expected that benefits as a result of current activities are consistent with national examples presented below. A study was conducted in Maryland in 2002 of the CHART Incident Management system. At the time of the study, CHART consisted of the following operational components: traffic monitoring, incident response, traffic management, and traveler information (i.e., live traffic cameras, real-time traffic maps, weather, and local traveler 7

19 information). The results below highlight the findings of the study of incident response savings realized by CHART Highway Incident Management operations: Reduced delay by about 30 million vehicle hours and saved about 5 million gallons of fuel Contributed to a 28.6% reduction in the average incident duration Resulted in 377 fewer secondary incidents, as a result of primary incidents, in 2002 The State of Georgia also conducted an evaluation of their NaviGAtor integrated ITS system. At the time of their study ( ) the ITS elements of NAVIGATOR included freeway management, incident management, multimodal traveler information, transit management, electronic toll collection, electronic fare payment, and traffic signal control, which constituted seven of the nine elements of the Intelligent Transportation Infrastructure. Six sections of I-75 and I-85 where ITS technologies were fully implemented (including operators, incident detection system, courtesy patrol, and cameras) were analyzed for incident duration only. Using before and after data and very conservative assumptions, each section was evaluated to determine the reduction in the average incident duration since NAVIGATOR was deployed. The study documented the following findings. A 23-minute reduction in incident duration during 1997 An estimated yearly cost savings of $44.6 million due to the above reduced delay time. It is expected that as CDOT continues the expansion and integration of ITS devices, incorporating new technologies and completing ITS Infrastructure coverage, the ITS Incident Management system will continue to yield similar if not greater results to the above documented studies.

22 II. Region 6 Corridor Analysis The following section describes the various corridors in Region 6 and the applicable ITS deployment strategies. Although not all corridors currently have ITS deployments identified, all corridors of significance in Region 6 have been included in this plan to facilitate the management of ITS projects on these corridors in the future. Table 2 shows a summary of the regional freeway and arterial corridors of significance. There are 9 freeway corridors and 23 arterial corridors. Table 2: Region 6 Corridors of Significance Freeway Corridors Arterial Corridors I-25 SH-2 C-470 US-6 I-270 SH-7 I-70 SH-8 I-76 SH-22 US-36 SH-30 I-225 US-40 US-6 SH-44 US-285 SH-53 SH-72 SH-75 SH-83 US-85 SH-88 SH-93 SH-95 SH-121 SH-128 SH-177 SH-224 US-285 US-287 SH-391 Transportation professionals across the country are utilizing a corridor approach to manage the public transportation network and identify ITS needs. A corridor management approach enables a comprehensive analysis of the network s existing infrastructure (capacity), transportation needs (demand), functionality and operational characteristics. Typical ITS applications resulting from this analysis are grouped below within the ITS Strategic areas that they help to implement: 11

23 Implement ITS Deployments that can Provide Benefits for both Freeway and Arterial Corridors and Commuters Traffic Operation/Management Centers (TOC/TMC) Serve as the focal point for the collection of corridor information and decision making and coordination based on corridor information Incident Management (IMP) and/or Event Management Plans Help manage and reduce congestion for corridors that experience significant amounts of incidents or events Traffic Responsive/Arterial Corridor Control Implement arterial corridor control to maximize corridor efficiency and dynamically respond to incidents and events System Detection Increase corridor system detection to empower Incident Management and Traffic Responsive capabilities along freeway and arterial corridors Variable Message Signs Increase the real time dissemination of traveler information to drivers along freeway and arterial corridors Courtesy Patrol Increase the coverage of this service, which reduces congestion and delay along freeways due to minor breakdowns and auto problems Ramp Meters Increase the use of ramp meters to maximize the capacity of freeways during peak rush hour periods Increase Communication Backbone/Infrastructure Coverage and Reliability to Support Wider ITS Deployment Communication Infrastructure (Fiber Optic Cable & Network ) Implement communication coverage to corridors where no coverage exists or to increase the connectivity, reliability and integration of all ITS devices. Increase Traffic and Incident Management Capabilities Throughout the Region on Freeway and Arterial Corridors Traffic Operation/Management Centers (TOC/TMC) Serve as the focal point for the collection of corridor information and decision making and coordination based on corridor information Incident Management (IMP) and/or Event Management Plans Help manage and reduce congestion for corridors that experience significant amounts of incidents or events Traffic Responsive/Arterial Corridor Control Implement arterial corridor control to maximize corridor efficiency and dynamically respond to incidents and events 12

24 System Detection Increase corridor system detection to empower Incident Management and Traffic Responsive capabilities along freeway and arterial corridors Closed Circuit Television Cameras(CCTV) Increase real-time observation coverage along freeways and arterial corridors Variable Message Signs Increase the real time dissemination of traveler information to drivers along freeway and arterial corridors Ramp Meters Increase the use of ramp meters to maximize the capacity of freeways during peak rush hour periods Courtesy Patrol Increase the coverage of this service, which reduces congestion and delay along freeways due to minor breakdowns and auto problems Increase Coordination, Access and Sharing of Corridor Data and Resources both within CDOT as well as with Regional Partners Outside of CDOT Traffic Operation/Management Centers (TOC/TMC) Serve as the focal point for the collection of corridor information and decision making and coordination based on corridor information Incident Management (IMP) and/or Event Management Plans Help manage and reduce congestion for corridors that experience significant amounts of incidents or events System Detection Increase corridor system detection to empower Incident Management and Traffic Responsive capabilities along freeway and arterial corridors Closed Circuit Television Cameras(CCTV) Increase real-time observation coverage along freeways and arterial corridors Additionally, the following Regional ITS strategies are planned or currently underway: Regional CCTV Map Display This will advance the concept of the Denver Region s virtual TMC by developing a common regional map display that incorporates and shows the location of all CCTV cameras in the Denver Region Denver Regional Arterial ITS Maps; Concepts and Guidelines This project will attempt to identify best practices for arterial street travel speed map displays CTMS Executive Desktop (CTMS Lite ) This strategy will develop a highlevel, simplified version of the CTMS software (CTMS Lite ) and make it available in view-only format to public agency executives with a focus on incident and emergency management applications During the Region 6 corridor analysis, CDOT and other stakeholders identified a total of 9 freeway and 23 arterial corridors of significance for ITS deployments in Region 6. 13

25 These corridors were selected based upon their high level of importance in supporting the commercial and personal surface transportation needs within Region 6. The 23 arterial corridors were then further segmented into 33 corridor segments. The 9 freeway corridors and the 33 arterial corridor segments result in 42 corridors identified for ITS deployments.
