• Abstract:
  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 (e.g., I-205) ; where “before” and “after” data are available. The intent will be to measure savings in delay, emissions and fuel consumption ; and safety improvements due to the implementation of the ramp metering system. Existing data sources are the ITS ; infrastructure and the statewide accident database, thus no dedicated data collection program is necessary. These two case studies ; will set a precedent for future evaluations of ITS programs. These evaluations are immediately feasible using existing data ; sources.
