Abstract
During the transition period when connected and automated vehicles (CAVs) and human-driven vehicles (HDVs) coexist on the roadway, miscommunication and improper interactions may lead to accidents due to lack of awareness of each other’s intentions. The most promising approach to this problem is to view roadway transportation as a cyber-physical-social system consisting of CAV, HDV, and infrastructure subsystems. Although adaptations of infrastructure are as critical as the technological advances of vehicles, the role of infrastructure in CAV and HDV interactions has not been fully acknowledged. We consider the roadway transportation system from the system-of-systems perspective, taking a human-centred approach that integrates the behaviours of human drivers and CAVs with the design and enhancement of transportation infrastructure. We provide an overview of prior studies regarding information-processing and communication of the subsystems. Interactions between HDVs and infrastructure are summarised by human driving behaviours and HDV crash analysis. Interactions between HDVs and CAVs focus on how they perceive and predict actions of each other. Interactions between CAVs and infrastructure are characterised by possible adaptations of infrastructure to support CAV navigation. Lastly, we propose a human-centred framework to provide guidance for research on and design of next-generation transportation infrastructure with CAVs and HDVs.
Relevance to human factors/ergonomics theory
Implementation of CAVs on the roadways with HDVs requires a system-of-systems approach that includes the CAVs, HDVs, and transportation infrastructure. Humans must be at the center of this approach because their actions are central to the success of the entire system.
