Driver's attitudes and preferences toward connected vehicle information system

Abstract

Connected vehicle (CV) and vehicle-to-everything (V2X) technologies enhance connectivity among vehicle, road user, and road infrastructure and can provide timely and concisely coordination information among drivers. Currently, there are far more studies on the technical aspects of V2X than on the demands of users. This study investigated the attitudes and preferences of drivers concerning the design of connected vehicle information system (CVIS) in this context. Focus group discussions followed by a questionnaire survey were conducted to gather driver's attitudes and preferences information. Results indicate that participants believed CVISs would help improve the efficiency of roadway communication, thereby improving safety, efficiency, and convenience of the overall traffic system. Visual warning signals and descriptive verbal speech were preferred over tactile warnings. Safety-related information (e.g., rescue services, reminding vehicle malfunction, and information about surroundings hazards) was valued most. Furthermore, age, gender, risk perception, privacy expectations, and technology inclination played essential roles in associating the attitudes toward CVISs. The outcome of this research provides an overview of the opinion of Chinese drivers toward CVISs and suggests practical implications regarding the design of CVISs for intelligent transportation.
