Abstract

A new strategy to enable an EV to navigate through congestion at signalized intersections more efficiently has been developed and is presented in this thesis. The proposed strategy involves communicating control messages to vehicles to change their driving behavior and to traffic signals to change their timing plans so that EV s can proceed through congested intersections as quickly as possible. To achieve this, specific vehicles are instructed to hold their positions to create a split in the vehicle queue at a critical location in one lane. The split allows the EV to change lanes and proceed unimpeded at its desired speed through the intersection while minimizing the disruption to background traffic. The proposed method uses shock wave theory to determine the critical split point in the vehicle queue. A microscopic traffic simulator is used for evaluating the effectiveness of the developed strategy. The results indicate that implementation of this strategy can reduce the response time of EV s.
