5 INTRODUCTION One of the major components of NIATT s strategic plan is to develop traffic control technologies that are useful to medium and small size cities. This project is part of NIATT s strategy to develop and apply the controller interface device (CID) technology as a key enabling technology for traffic engineers in the testing and deployment of traffic controller systems and in the training of traffic engineers in the design of traffic controller systems. This project will provide the research infrastructure necessary to develop and test a new traffic control system as part of the City of Moscow signal integration project. The laboratory facilities will be used to train engineering graduate and undergraduate students and traffic engineers in the design and operation of traffic control systems. NIATT s Traffic Controller Lab is a significant addition to the research infrastructure in the nation and is poised to become a world-class research and training center, where practicing engineers, researchers, and students can develop and test traffic signal timing plans on actual traffic controllers, using state-of-the- art hardware and software. NIATT s existing lab will be substantially expanded this year, to provide the hardware and software infrastructure for testing timing plans on up to 20 intersections at a time, with hardware-in-the-loop simulation and NIATT s new Controller Interface Device (CID). NIATT s expanded Traffic Controller Lab will initially be used to develop and test signal control strategies for the traffic signal network in Moscow, Idaho. The $1.5 million Moscow ITS project includes developing new signal timing strategies for Moscow s 15 intersections and testing them in NIATT s Controller Lab using real-time hardware-in-the-loop simulation. This is the first time that a system of this size will be modeled prior to deployment using hardware-in-the-loop simulation and the CID. Funding for the Moscow ITS project and the NIATT Controller Lab is being provided by the Federal Highway Administration, the U.S. DOT's University Transportation Centers program, and donations from the traffic control industry and the University of Idaho. The lab facility will also include two other components: an Advanced Traffic Management virtual lab funded through the ITD/UI Cooperative Transportation Research Program, the FHWA, and the USDOT UTC program, and a Transportation Planning TRANSIMS-DOT Traffic Controller Laboratory Upgrade 1

6 system for modeling large scale transportation networks, funded through the FHWA, the USDOT UTC program and the University of Idaho. Details of the lab layout are presented in the following figure. PROJECT GOALS AND OBJECTIVES The primary project objective is to expand the capabilities of NIATT traffic controller laboratory, located in room 108 in the engineering and physics building at the University of Idaho campus. Once completed, the upgraded lab will provide a research and educational facility that allows traffic engineers, practitioners, and students to develop, test, and analyze signal timing plans and control strategies using hardware-in-the-loop simulation environment for traffic signal system networks with up to twenty intersections. The goals of this laboratory are as follows: Provide a facility for undergraduate and graduate laboratory instruction. Provide a facility for conducting research on Advanced Traffic Management Systems. Provide a facility for disseminating state of the practice in traffic management and freeway/arterial systems operations to practicing professionals in both the public and private sector. The initial requirements for the lab are: 20 Traffic signal controllers from different types (NEMA, 170, and 2070) 20 Controller Interface Devices (CIDs) and CID communication hubs 4 Laptop computers for control software and traffic controllers setting 4 Computer workstations for running the simulation software 3 traffic controller cabinets An easily configurable communication infrastructure for networking the traffic signal controllers in a flexible manner Traffic Controller Laboratory Upgrade 2

10 RESULTS/CONCLUSIONS Power requirements for each piece of equipment in the new lab design were calculated. The calculated values represent an approximate max current load for the device. Final calculation for the overall load requirement will take into consideration all equipment plus allowance for future expansion and flexibility. Refer to Appendix A for a list of Equipment Load requirements. After discussing the list of power requirements with facilities personnel, it has been determined that the current laboratory setup cannot support our requirements. The lines on both east and west sides of the lab will not be able to power all of our desired equipment; however, the building does have available all the power needed. Additional lines can be wired into the lab. As a design recommendation, two or three additional lines must be installed on the east wall of the lab (for a total of three or four lines) to support the 4 CID subunit racks, data server and workstations. For the west wall, two more lines must be installed (for a total of three lines) to support CID development equipment, workstations, projectors, and data/video servers. For cost purposes, it might be in NAITT s best interest to run our own surge protectors from the lines to the equipment. Currently there are a total of 10 available outlets on the east wall of the lab, arranged in groups of two spaced every 3 feet. The west wall has 18 available outlets; these too are arranged in groups of two spaced every 3 feet. The east wall equipment will require a minimum of 64 power outlets; however, design for this number of outlets should be in a combination of additional outlets physically on the wall and piggy-backed surge protectors on the subunit racks. Traffic Controller Laboratory Upgrade 6

11 As a design recommendation, I would recommend that the number of outlets located on the east wall be increased to 20 outlets, five groups of four outlets every 3 feet. The subunit racks could possibly consist of 3 piggy-backed power strips/surge protectors that have a single connection to the wall. For future expansion and new lab design; the number of outlets on the west wall must be increased to 36 outlets. Similarly to the east wall, nine groups of four outlets every 3 feet. The number of Internet Ethernet connections also needs to be increased in the new lab. Currently there are six Internet Ethernet connections on the east wall and six Ethernet connections on the west wall of the lab. The connections are in two groups of three on each side of the lab. As a design recommendation, that three Ethernet connections must be placed with the outlets at every 3 feet grouping. Traffic Controller Laboratory Upgrade 7

12 APPENDIX: POWER VERIFICATION AND DESIGN REVIEW Goal/Objective Determine an approximate load requirement for each piece of equipment in the new lab design, determine total laboratory load requirements. Verify if the power distribution lines of the NIATT Traffic controller lab can support the desired load requirements of the new lab design and equipment power consumption needs. Determine the number and location of additional wall-outlets that need to be installed in the lab to support the equipment. Determine the number and location of additional Internet LAN Line connections that need to be installed in the lab to support the equipment. Allow for flexibility.
