Consider the implications of ITS transit technologies on operational efficiencies.
Experience from the Lake Tahoe Coordinated Transit System.
- Consider the size of the service area when designing the Computer-Aided Dispatch system. The CST CAD system was designed for traditional paratransit systems where individuals are picked up and dropped off one at a time. This CAD system design was better suited for the casino shuttle, which had a limited service area, rather than the door-to-door service area, which was about 4 times the size. The large service area, longer distance trips, and limited funding for deployed vehicles created a situation where the CAD system provided minimal efficiency for the door-to-door service.
- Be cognizant of the processing time associated with scheduling rides through the automated system. The automated system used in CST provides little efficiency in scheduling rides. Dispatchers have found that they can address a trip request in approximately 5 to 6 seconds in person, whereas they have found that it requires approximately 90 seconds if the computer books the trip. While the automated system has reduced the number of calls coming into the dispatch center, the increased processing time affects the system efficiency.
