Integration of vehicle platooning in highways with mixed traffic

Vehicle platooning

We investigate how to design vehicle platooning operations for maximal efficiency and environmental benefits. We develop multi-class fluid queuing models for highways with mixed autonomy and focus on the interaction between CAVs and ordinary vehicles. Our performance metrics include travel time, throughput, and safety level.

Automatic highway control under stochastic perturbations

Ramp metering

We design feedback ramp control policies that improves throughput under stochastic capacity disruptions. We come to a rather surprising conclusion: prioritizing the link with a higher utilization ratio is not necessarily optimal; instead, the link with a smaller capacity-demand margin should be prioritized. We are also evaluating our results via simulation of calibrated models.

Cyber-physical disruptions of transportation networks

V2I

We model and analyze the impact of cyber vulnerabilities on smart highways. We consider the resource allocation problem for recovery processes and adaptively react to detected attacks. We also study the incentives of strategic misbehavior by individual vehicles who can exploit the security vulnerabilities in V2I communications and impact the highway operations.
