This report describes a simulation study of combining fixed-route bus systems with dial-a-bus systems. The report also describes and discusses the methods used and the factors influencing costs and travel time of a dial-a-bus system. Two alternatives were studied: (1) max travel time; the dial-a-bus system takes care of all journeys, which in the fixed-route system have travel times longer than 45 minutes and 55 minutes respectively. (2) higher charge; the dial-a-bus system can be used for all trips within the city but the charge for this system is considerably higher than for the fixed-route system. Two levels of investment have been studied, 10 and 20 buses respectively. These levels correspond to the charges 30 skr/trip and 20 skr/trip. The high standard of the dial-a-bus system creates problems by greatly raising the travel demand compared to that of the fixed-route bus system. The dial-a-bus system attracts travellers that previously used cars, bicycles or walked. The alternative max travel time gives reduction of travel times up to 30 min, and the costs increase by 0-40% (45 min) and 35-80% (55 min). The alternative higher charge gives hardly any reduction in travel time and would in practice work as a more efficient taxicab system. The charges would easily finance the increased costs. (TRRL)
