This paper reports the development of the road traffic simulator to analyze the effectiveness of the rapid-charge station (ST). The road model in the traffic simulator is based on the digital map 25000 produced by Geospatial Information Authority of Japan. A multi-agent simulator for complex systems "artisoc" is applied to implement the algorithms for traffic simulation and the road model into the traffic simulator. The validation on the traffic simulation is carried out by using the traffic database of the person trip survey. The simulation results on the trip number inside the city and between cities are consistent with those of the person trip survey. To analyze the effectiveness of ST arrangement, the EV traffic simulation is carried out by the traffic simulator developed in this paper. This road map model in this traffic simulation corresponds to the road map of 10 cities (A-J), where the area and population are 2600 km2 and about three million people, respectively. We assume the conditions of the accessory power ...... = 3.0 kW and the traffic jam. According the simulation results, the support of 17 STs enables to keep the averaged EV travel length of 37 km, which corresponds to the traffic data of the average travel length per day for the Japanese household car. This result also suggests the area responsible for a ST is about 150 km2 per ST(i.e. one ST in the area of about 12 km square). This result is similar to the ST development target in Kanagawa prefecture proposed by the Kanagawa EV promotion council in 2008. This traffic simulator can also analyze the availability of each ST. The time evolution of the number of the EV charged at a certain ST is shown in this paper. This result is helpful to discuss how many rapid-charging devices have to be prepared in a ST. Finally, those results show that the traffic simulator developed in this paper is very helpful to evaluate the effectiveness of the rapid-charging station.
