Samenvatting
This paper presents findings on initial changes in service reliability following the deployment of a new bus dispatching system using automatic vehicle location and automatic passenger counter technology by Tri-Met, the transit provider for the area of Portland, Oregon. Changes in on-time performance, headway variation, run time variation, and run times were determined with respect to predeployment levels. Changes in headway variation and run times were also used to estimate the initial benefits of the new system with respect to operating costs, passenger waiting, and passenger travel time. (A)
