Effects to Display Traffic Signs inside the Cabin on the Driving Behavior

Abstract

Road signs are essential to realize safety and smooth traffic flow. Drivers sometime overlook and miss the sign suggestions because they are concentrating on driving operations. In the literature, many researches focus on providing information via in-vehicle instruments in order to avoid driving burden. However, few researches evaluate effects of such in-vehicle interfaces on the driving behavior. In this study, three ways of providing information, i.e., only with road traffic signs, with road and in-vehicle traffic signs, and with road and another type of in-vehicle traffic signs, are investigated using a driving simulator, and theirs effects on driving behavior are compared.
