Intelligent Transportation Systems Laboratory's Featured Project:

Using Archived Data to Measure Operational Benefits of ITS Investments

The objective of this project is to use the existing data, surveillance and communications infrastructure (to the extent possible) to develop two case study evaluations for Oregon, including an evaluation of the COMET incident management program and the Portland ramp metering system. The COMET evaluation will include a thorough literature review of other incident management program evaluations, as well as a determination of the costs and benefits of the program. Benefits will include reduction in vehicular delay, fuel consumption and emissions due to early incident response, prevention of secondary accidents as well as benefits stemming from public perceptions. To the extent possible, the existing ITS infrastructure, Oregon State Patrol computer aided dispatch database and statewide accident database will be used as data sources to minimize the amount of new data collection required. It is envisioned that one corridor will be selected for a focused analysis, using video surveillance to observe actual incident durations and COMET response times. The ramp metering system case study will select a corridor where
