Effect Verification of Information Provision for Vehicle-Infrastructure Cooperative System - Result of Aichi DSSS Field Verification Test

This article describes the results of a study in Toyota-City about vehicle - infrastructure cooperative systems. In the field verification, roadside equipments were installed at selected intersections, and on-board units were equipped for the each test vehicles and recorded the driving action of a driver. Then change of driving actions of the test drivers resulting from driver information at traffic signals was observed. The driver information influenced release timing of acceleration pedal. This was clearly shown in data between the state of green signal and red signal. For future study, in order to inspect the safety effects of the systems, methods and appropriate parameters need to be found to extract the change of driving actions. Moreover, it is necessary to look at the effects when the driver gets used to the information supports over a period of time. For the covering abstract see ITRD E140665.
