Summary Information

This research proposed an eco-driving system for an isolated signalized intersection under partially Connected and Automated Vehicles (CAV) environment. This system was designed to prioritize mobility before improving fuel efficiency, and optimize overall traffic flow by optimizing speed profiles for connected and automated vehicles.

METHODOLOGY

Simulation-based before and after evaluation of the proposed design was conducted. The optimal control problem was solved using Pontryagin’s Minimum Principle.

FINDINGS

Throughput benefits ranged from 0.88 to 7.06 percent under a saturated traffic condition and from 1.74 to 10.80 percent under an oversaturated traffic condition. Variations were caused by the market penetration rate of CAVs. No adverse effect is observed when traffic was under-saturated.
