DIAL-A-BUS SYSTEM IN TRAFFIC SEPARATED AREAS

In many new housing areas, public transport is remote from the users. One way in which this situation can be improved is introduction of a telebus system, i.e. a demand responsive public transport system. The aim of this study was to examine the criteria for a telebus system, to examine the feasibility of the system in areas with traffic segregation, and to plan possible routes and pick-up points in such areas. The following conclusions and recommendations are made: (1) level of demand is very important for economical operation, and should be 8-25 journeys/square km/hour. Areas with less than 4000 population/square km are recommended. (2) layout of street network appears to be of secondary importance; cul-de-sacs should however be few and short. (3) the system is very flexible and can operate even in areas with traffic segregation, provided that housing density is low and accessibility is not unduly bad. (4) telebus operation should be allowed for in planning a traffic network for low-density areas. In traffic-segregated areas also, telebus operation is possible if some modifications are made. (5) the system can be introduced in many areas in Sweden, particularly in view of the increase in the number of old people and detached houses. /TRRL/
