Benefits and Challenges of Integration of High-Capacity Autonomous Buses to Public Transport Operations

High-capacity autonomous buses can make bus travel safer, smoother, and more energy efficient. However, despite clear societal and environmental benefits there are still several challenges to be addressed. In this article we present the outcomes of two research projects focusing on the public acceptance of high-capacity autonomous buses. Results indicate high degree of trust towards automation safety. However, in certain conditions, such as driving alone at night, perceived security appears to be an issue. In such circumstances digital forms of assistance replacing drivers will most likely not guarantee a sufficient degree of security. The paper also argues that bus automation is not a silver bullet to make PT more attractive. Instead, it shall be seen as rather an enabler of new applications allowing to efficiently prioritize PT in traffic flows to make it an attractive choice.
