10 The Challenge Can we change this part of the Traffic Control Plan? We really need to get this work done next week! We have these 8 major projects going to construction next fall, what will traffic be like? We have a conflict! We closed the left lane and someone else is setting up to close the right lane! HELP! If we close this ramp for the next 2 months, what detour alternatives do we have? Why is the right lane closed again, when the utility company just finished their work? 10

11 THE APPROACH 11

12 The Approach DDOT Needs a Dynamic and Regional Approach to Managing Work Zones! Citywide TMP / Work Zone Project Management System Five-year moving period Proactively track and analyze work zone & special event impacts Identify areas of significant cumulative impacts Generate cost-effective mitigation strategies Timely responses to stakeholder question and concerns Improve safety and mobility 12

21 The Approach: Traffic Analysis Tool Custom mesoscopic simulation model Simulates operations during construction Link capacity reduction for work zones Roadway and traffic signal data Traffic volumes Traffic analysis scenario framework Generates various maps and tables TRAFFIC ANALYSIS TOOL Analysis summary reports Weekday peak period scenario results Regional congestion hot spot map TMP / MOT alternatives Identify and minimize cumulative work zone impacts 21

22 The Approach: Traffic Analysis Tool Project Map 22

23 The Approach: Traffic Analysis Tool Delay Map Intersections Segments Total Time or Percent Increase Level of Service Map 23

24 The Approach: Traffic Analysis Tool Hotspots Map 24

25 The Approach: Citywide TMP Document Produced Annually Focus on Cumulative Work Zone Impacts Does not replace project-specific TMPs Year 1 (Baseline) Scope Principle Arterials and Higher DDOT Capital Projects Weekday AM / PM Peaks National best practice research TMP Team input and lessons learned Community hot spots CITYWIDE TMP Document Development 5-years worth of work zone mitigation strategies Customized regional TDM plans Mitigation strategy budget estimate Identify corridor / area work zone mitigation strategies 25

26 The Approach: Citywide TMP Document Describes Citywide Work Zone Project Management System SmartNET Traffic Analysis Tool Identifies major projects, key corridors, and potential conflict areas Provides recommendations for mitigation strategies Transportation Demand Management (TDM) Public Outreach Formalizes five-year plan for implementing work zone mitigation strategies Documents success of program through performance measures 26

46 Work Zone Mitigation Strategies Goal: Maximize mobility while minimizing impacts Supplement project-specific mitigation strategies Two (2) primary types of regional mitigation strategies Citywide initiatives Targeted strategies for identified hotspots 46

47 Citywide Initiatives Use of Citywide Work Zone Project Management System Software Tools SmartNET to avoid work zone conflicts Traffic Analysis Tool to avoid cumulative impacts Promote coordination between projects Citywide Work Zone Project Management Website Portal for travelers to obtain work zone information Recommendations for alternative routes & travel modes Comprehensive map of all major construction activities Construction schedules Major TDM strategies 1 of 3 47

48 Citywide Initiatives Public Information Campaign Targeted outreach along critical corridors Goals: Alert the public about potential impacts and means to avoid them Improve public awareness and understanding of major projects Modify travel habits to reduce congestion Tools: Public opinion survey Advanced Strategy Online (ASO) Brochures & Fact Sheets Traditional & Social Media Portable Changeable Message Signs (PCMS) 2 of 3 48

49 Citywide Initiatives Transportation Demand Management (TDM) Review existing, approved TDM plans Develop new customized TDM plans and manage the implementation of TDM plans along critical corridors Commuter Club 3 of 3 Members will be able to track work zone construction and the best ways to avoid disruptions 49

50 Mitigation Strategies For Hotspots Schedule Changes Example: Should start of 16 th Street project be delayed to avoid cumulative impacts with U Street project? Changeable Message Signs (CMS) Use existing permanent signs or temporary portable signs Public Outreach for Affected Communities Promote alternate routes and off-peak travel Highway Advisory Radio (HAR) Reconsider Peak Hour Lane Closures Establish congestion threshold to re-open lanes Automatic speed and volume detection 1 of 2 50

51 Mitigation Strategies For Hotspots Signal Timing Adjustments Real-Time Traveler Information Coordination with MDOT / CHART Transit Incentives / Bridge Bucks Transit Improvements Add circulator buses, bus pull-off areas, bus pre-emption Geometric Changes Reversible lane, restrict turn movements, modify lane configurations, restrict parking during peak hours 2 of 2 51
