Investigating the Effectiveness of an Eco-Speed Control System in the Vicinity of Signalized Intersections Using a Driving Simulator

This study utilizes a full-scale high-fidelity driving simulator to investigate drivers’ response and compliance to Eco-speed control systems in the vicinity of a signalized intersection, and the effectiveness of such a system in reducing emissions. An Eco-driving guidance is implemented in the driving simulator, and participants are given a voice-activated recommended speed every two seconds while driving toward an intersection in different scenarios of traffic conditions and road characteristics. Their speed profiles and the produced CO₂ emissions are compared with driving the same road without any guidance and also with a countdown traffic signal. Descriptive and statistical analyses including Generalized Linear Models (GLM) and t-tests are performed on the data obtained from 58 participants with various sociodemographic backgrounds who in total drove more than 2,000 times. The results show that men and younger drivers are more likely to follow the recommended speed. The emissions calculations indicate that an Eco-speed control system decreases the emissions level 9.1% more than countdown timing systems do and the emissions level is lower in the countdown timing system compared to conventional traffic signals.
