Developing a framework of Eco-Approach and Departure application for actuated signal control

The Eco-Approach and Departure application for fixed-time traffic signals, which uses the signal phase and timing information from the upcoming traffic signal to better guide a driver through the intersection in an environmentally-friendly way, has shown promising results in terms of fuel savings and carbon emissions reduction. However, there is very limited research on the development and evaluation of such application for actuated traffic signals. This paper proposes a framework for the Eco-Approach and Departure application for actuated signals which takes into account uncertainties in count-down information, preceding vehicle´s state, and potential driver´s distraction issues. The framework has been evaluated with numerical experiments. The results indicated that the proposed framework is effective at reducing energy consumption and emissions of the equipped vehicle, especially when the initial entry speed is relatively low.
