| Abstract The current Society of Automotive Engineers (SAE) Level 2 (automated acceleration and steering capabilities) autonomous vehicles on the market require constant monitoring and intermittent interventions by the driver whenever the system reaches its limitations. Although drivers’ workload could be increased in the processes, interactions associated with them have rarely been explored in a naturalistic environment. Therefore, our understanding about drivers’ interaction with the current generation of autonomous vehicles seems limited. In order to extend the relevant knowledge, this paper investigates drivers’ interaction with a semi-autonomous vehicle in a complex naturalistic urban environment. Five drivers with varying levels of experience in autonomous cars participated in the experiment. Findings show that active monitoring was required in automated driving for safety to gain sufficient situation awareness that preceded manual interventions in certain conditions. The process seemed to be smoother for the experienced drivers as they had a better understanding about capabilities and limitations of the autonomy. Insights to automotive manufacturers on how driver-vehicle interaction could be enhanced are discussed. |
