Abstract
Some opportunities and benefits of integrating conventional and flexible-route services will be discussed, including the following:
1. Conventional services (with fixed routes and schedules) and Dial-A-Ride (DAR) paratransit services (with flexible routes and schedules) offer a spectrum of service types with various combinations of service quality, capacity and cost. Normally, conventional services must acquire sufficient vehicles and drivers for peak period requirements, but these are largely wasted at most other times. By switching vehicles and drivers to different types of services as demand changes cyclically over time, we may offer more responsive door-to-door services during off-peak periods and transform the excess capacity of conventional services into a range of DAR services with lower capacity but higher quality.
2. By providing services of higher quality during off-peak periods, some users can be diverted from peak periods, thus reducing total resource requirements and congestion effects. Such beneficial diversion as well as other efficiencies may be further promoted with reservations, incentives and pricing options.
3. By using DAR services to concentrate passengers on conventional services rather than just compete with or substitute for them we can bring each service type closer to its ideal operating conditions.
4. Further synergies of integration may be sought in coordinating the arrivals of vehicles at transfer stations through efficient routing, scheduling, slack time in schedules, real-time dispatching decisions at transfer stations, and traffic signal control.
Short Biography
Dr. Paul M. Schonfeld has been a Professor in the University of Maryland, College Park since 1993. Dr. Paul obtained his Bachelor’s and Master’s degree in Massachusetts Institute of Technology, and Doctoral degree in University of California, Berkeley. He has been conducting research on Urban Public Transportation Systems, Transportation Systems Analysis, Maintenance Planning and Scheduling, Air Transportation, and Freight Logistics. About 40 years’ rich experience with transportation engineering has been accumulated. Dr. Paul took in charge of multiple projects about ‘Flexibility and Responsiveness in Public Transportation Systems’, ‘Integration of Conventional Transit and Paratransit Services’, and ‘Integration of Multi-modal Transportation Services’ in recent years. He has published well over 150 SCI papers, and 7 monographs. The academic achievements were widely recognized and practiced.
