Abstract

With the accelerating industrialization of 5G-V2X and smart automobiles, the intelligent connected vehicle (ICV) integrated with sophisticated communication, caching, computing, and control techniques enhance the functionality of in-vehicle infotainment (IVI) and also provide more powerful telematic or entertainment choices in vehicular environment. The diverse needs of ICV users (e.g., drivers and passengers) can be satisfied during commuting and traveling. However, considering the limitations of transportation environment, the potential attitude and usage behavior for the upcoming ICV infotainment directly impacts on the traffic and road safety in sustainable cities. In this paper, we conduct an online and offline survey to investigate the key factors influencing the user attitude and intention of ICV infotainment, where the answers of a total of 502 valid respondents (i.e., IVI users) are collected in China. A conceptual technology acceptance model with the constructs of perceived usefulness (PU), perceived ease of use (PEOU), social influence (SI), consumer innovation (CI), and perceived risk (PR) is established, and then assessed via partial least square structural equation modeling. We find that the constructs of PU, PEOU, CI, and SI have a direct impact on attitude and usage intention, of which 46.8% and 73.4% of variance, respectively, are explained. The respondents show positive attitudes and higher usage intention towards the ICV infotainment. Although PR has insignificant path with attitude and intention, the driving experience moderation effect exists between PR and usage intention. We can see that ICV infotainment will become a trend in future transportation scenario. Through this survey, reference for traffic safety and usage norms will be provided to reduce the risky of public health issues (e.g., traffic accidents) in the context of ICV infotainment.

Highlights

With the advantages of massive connectivity, higher data rate, ultra-reliability, and lower latency empowered by 5G technique, 5G-V2X as the new evolution of Internet of Vehicles (IoV) paves the way for next-generation Intelligent Transportation System (ITS) and automobile industry
We have investigated the users’ attitudes and behavioral intentions (BI) towards intelligent connected vehicle (ICV) infotainment in 5G-V2X scenarios among the participants who previously experienced in-vehicle infotainment (IVI) services
We found that IVI users opt to follow the advice from their friends and family members during the decision-making process

Summary

Introduction

With the advantages of massive connectivity, higher data rate, ultra-reliability, and lower latency empowered by 5G technique, 5G-V2X (vehicular-to-everything) as the new evolution of Internet of Vehicles (IoV) paves the way for next-generation Intelligent Transportation System (ITS) and automobile industry. Traffic safety and efficiency can be improved via perception, planning, and control in transportation environment [1,2]. The intelligent connected vehicle (ICV) equipped with the critical functions of communication, caching, computing, and control provides comfort usage experience and omnimedia services both for drivers and passengers in cabin environment, which elicits positive perceptions among consumers [3]. Depending on onboard modules and road-side units, ICV gradually became a real-time information platform to undertake the role of decision-making, data discovery [6], and mobile content generation [7] in smart cities.
