This paper proposes the development of an ecological driving assist system (EDAS) that can receive instant road-vehicle-traffic information from ITS sensing and communication technologies, and provide drivers with eco-driving assistance by anticipating possible behavior of leading vehicles and traffic signals ahead.

Performance of the proposed system was simulated using the AIMSUN NG microscopic simulation model applied to a simplified vehicle traffic configuration. The system was designed to minimize fuel consumption per unit distance by providing drivers with input that could be used to reduce unnecessary braking and acceleration in various driving situations. For computational simplicity, only the longitudinal motion of a host vehicle, lead vehicle, and a signalized intersection were assessed. The potential impacts of other traffic around the host vehicle or vehicles in front of the lead vehicle were not included in the analysis.

Vehicle performance was measured with and without driver assistance. Baseline data representing performance without assistance were generated using the AIMSUN NG base model (Gipps Method). EDAS features were applied using an application program interface (API) and recommendations for driver assistance were generated using the generalized minimum residual (GMRES) method.

The model assumed that all actions recommended by the system would be executed properly by the driver. Fuel consumption parameters of a subcompact car were used to quantify the average fuel savings and travel economy benefits.
