Behavior of driver and vehicle passing a pedestrian on local streets

Abstract

Recently, car manufacturers are developing automobile active safety systems to prevent traffic accident. Active safety systems include automated driving system, AEB (Automatic Electric Brakes), ESC (Electric Stability Control), LAKS (Lane Keeping Assist System), IPAS (Intelligent Parking Assist System). It is important for the system to make drivers understand the system easily and operate appropriately. Driver's acceptability of the system will increase when the system functions in the same way as a driver. It is necessary to research driving behavior to emerge the systems that enable us to use comfortably and unmistakably. In this paper, we study behavior of a vehicle when the vehicle passes a pedestrian on the local street. We measured some quantities of vehicle behavior such as trajectory, acceleration, steering angle using a vehicle on the test course which simulates the local street. In the experiments, the subjects are chosen with various driving record and frequency of driving. As a result, it is revealed that characteristics of vehicle behavior depend on driver's skill and frequency.
