With the continuous development and popularity of the automobile industry, people's demand for mobility has gradually increased, which in turn has caused traffic congestion and risen energy consumption. In this paper, based on the C-V2X technology, combined with traffic flow simulation model IDM and fuel consumption evaluation model VT-Micro, the speed advisory algorithm is optimized to improve the problem of high collision risk between the single connected vehicle and queuing vehicles when the single connected vehicle drives to the congested signalized intersection. The simulation results indicate that the stability of the vehicle's driving status can improve the fuel economy. The speed optimization algorithm proposed in this paper can effectively avoid the risk of vehicle collision and significantly reduce fuel consumption by approximately 47% when facing congested signalized intersections.
