Study on Cooperative Driving of Automated Driving Vehicles through Shared Spatial Information Infrastructure

Abstract

This paper proposes a method of cooperative driving of automated driving vehicles. In the proposed method, the vehicles share the information of their intention such as future pathway, velocity and so on, through the spatial information infrastructure by long-period (about 1s) N:1 communication. Each vehicle can decide its driving strategy considering the shred information of other vehicle’s intention, resulting in smoother flow of traffic than that realized by automated driving judging the driving strategy based on the sensor information. This paper explains the proposed cooperation method and reports the evaluation results.
