A mobility system involves the interactions of three heterogeneous features: 1) transportation systems and modes, e.g., connected and automated vehicles, electric vehicles, public transit, and shared mobility, 2) social behavior of drivers and travelers interacting with these systems, and 3) institutional behavior of organized units such as regulators that govern the transportation systems through policies. Current methods design and analyze mobility, which can be referred to as a sociotechnical system, with each of these features in isolation resulting in lack of the understanding of their interdependence, and thus, unbalancing of travel demand and given capacity of the transportation network. The latter has significant implications on traffic congestion, energy consumption, travel delays, safety and eventually, frustration that directly impacts the quality of life. Although several research efforts have aimed at enhancing our understanding of improving next generation mobility systems, it appears that these systems are considered in isolation without deliberating on human perception and policies. This can lead to solutions that demonstrate a selfish rather than system-centric or “socially” optimal behavior. The workshop intends to stimulate a discussion on how we can develop an energy-efficient mobility system from a sociotechnical systems perspective.

Workshop Scope: This workshop will cover the following topics:

• Implications of energy on next-generation mobility systems
• Negative effects of improving the efficiency of transportation systems; exploring whether household activities and travel behavior might increase if the efficiency of the transportation system improves
• Social attitudes, e.g., human emotional responses, with respect to connected automated vehicles, electric vehicles, shared mobility, and public transit, and the policies that can help us increase the public's level of acceptance of these transportation systems
