| 摘要： | This report presents the results of the evaluation of the I-5/Barbur Boulevard Parallel Corridor Traffic Management Demonstration Project, a cooperative project between the Oregon Department of Transportation (ODOT) and the City of Portland to integrate incident management along a high-volume freeway-arterial corridor south of downtown Portland (defined as the Study Area). The evaluation approach was to collect data to assess the impact of the traffic/incident management system on customer satisfaction, system efficiency, and traveler mobility in the corridor during incident conditions. A panel survey of drivers who commute northbound in the Study Area was established to which to administer a series of incident surveys to gain perspective on their perceptions of and satisfaction with traffic conditions in the corridor during incidents. To assess system efficiency and traveler mobility, ODOT provided volume, speed data, and secondary incident information for I-5, and TriMet (the public transit provider in Portland) provided speed data from bus probes along Barbur Boulevard. The results of the customer satisfaction study showed that although customer satisfaction ratings of traffic conditions in the corridor during incidents have not significantly improved since the incident management system was deployed, reported commute times during the After incident were shorter than reported commute times during the Before incident. This response occurred despite the fact that the After incident was a much more serious crash, blocked more lanes, and lasted longer than the Before incident. |
