Federal Highway AdministrationUS Transportation CollectionThe goal of the project was to design and implement an in-vehicle system that calculates and provide speed advice to the driver of the vehicle, using Signal Phase and Timing (SPaT) and Geometric Information Description (GID) information of the signalized intersection, allowing the driver to adapt the vehicle's speed to pass through the upcoming actuated traffic signal(s) on green or to decelerate to a stop at a red signal in the most environmentally efficient manner. The testing of the system revealed that the fuel saving performance varies from 0 to 22 percent for different driving scenarios. The three scenarios of "speed up to pass (during green)", "have to stop (from green to red)" and "maintain speed to pass (from red to green)" can potentially make improvement by following in-vehicle speed advisory recommendations. Having considered the occurrence chance of every scenario, the statistical results show that the real achieved benefit for the tests ranges between 3% to 4%. This work was performed as part of the California PATH program of the University of California Berkeley and UC Riverside, in cooperation with the State of California Business, Transportation and Housing Agency, Department of Transportation, and the United States Department of Transportation, Federal Highway Administration
