Optimizing CAV platoon movements in a signalized road network for travel and energy efficiency

The research team's previous work to optimize CAV platoon movements through an isolated intersection has shown that considerable savings (up to 40%) in both travel time and fuel use can be achieved. In this research, the team attempts to solve the CAV platoon optimization problem for a network of signalized intersections, which presents several challenges that their previous work did not address. In this research, the team proposes a cooperative platoon-trajectory-optimization framework that consists of four components: optimal route planning to identify the CAVs travel paths based on the real-time traffic state, a lane-changing strategy to form platoons for different travel directions, boundary control for generating the initial and final states of optimization, and a platoon-trajectory-optimization method to minimize the fuel consumption and travel time. Simulation studies will be carried out to evaluate the system performance of the proposed framework in reducing fuel consumption and travel delay.
