| Abstract(in English) | In this paper, in order to clarify the desired ITS information and communication systems considering both safety and social feasibility, from the overengineering prevention point of view, we discuss the required information acquisition rate of three types of safety driving support systems, that is, the sensor type and the communication type, the sensor and communication fusion type, using “TsRm evaluation method” that considers a vehicle approaching within the range of R meters within T seconds as the vehicle with a high possibility of collision, and that evaluates only those vehicles. As extended study, especially the authors have been doing so far, on the sensor type and the communication type, and the sensor and communication fusion type systems by "TsRm evaluation method " using a microscopic traffic flow simulator on ordinary roads, we discuss the required information acquisition rates of these three types of systems in various vehicle penetration ratios and various congestion ratios. The result show that regarding the communication radius and the sensing range, overengineering performance may be estimated when all vehicles in the evaluation area are used for evaluations without considering each vehicle’s location, velocity and acceleration as in conventional evaluations. In addition, it is clarified that the sensor and communication fusion type system is advantageous by effectively complementing the defects of the sensor type systems and the communication type systems. |
