Abstract
This paper reports simulation results of smart acces vehicle (SAV) service for a middle-sized city, Hakodate, JAPAN, to evaluate utility of SAV compared with a traditional bus system (i.e. route-bus). And we propose the simulation environment SAVSQUID (SAVs Simulator for Qualitative Utility Investigation and Design). One of difficulties of introduction of such ’smart‘ transportation systems is hardness of predicting how well the system works and is used by citizens and/or tourists. Our previous work of simulation of such smart systems showed a smart system could perform better than fixed-route bus systems in large-scale operation in a virtual city under ideal conditions. In order to confirm the result in a real city, Hakodate, we try to investigate effects and features of SAV based on actual road map, costs, and realistic conditions (ex. acceleration, deceleration, boarding and alighting time, and more). The simulation by the real data shows several interesting properties of the realistic smart system. Therefore, simulation environment SAVSQUID is constructs three part, traffic physical simulator, vehicle's demand / routing controller, exhibit simulation controller. SAVSQUID could reveal the condition of service conditions. The result of SAV simulation through the SAVSQUID shows some difference of virtual situations. This result suggests, importance of realistic conditions including physical conditions on those simulations.
