Route guidance is an efficient method to improve the capacity and efficiency of traffic system. This paper proposes an advanced ecorouting guidance strategy based on the real-time feedback information of both fuel consumption and travel time under the background of intelligent transportation system. Compared with the geographical shortest path strategy (GSP) and the time shortest path strategy (TSP), simulation experiment results show that the new strategy can help save fuel consumption and
