Abstract: To clarify the impact of steady traffic (ST) and stop-go traffic (SGT) on the energy flow of moving vehicles contributes to a deeper understanding of signalized intersection’s traffic optimization mechanism. In this paper, the theoretical model of vehicle energy was improved based on vehicle driving states, 3 energy evaluation indexes were proposed, and 6 vehicle cycles experiments were carried out in ST and SGT. The results show that: (1) The internal energy consumption of vehicles is the main direction of the total tank energy flow of vehicles, ST reduces the flow intensity of total tank energy to internal energy by 1.2% and increases the distribution force to friction energy consumption by 22.9%, which makes the energy distribution of moving vehicles more uniform. (2) ST weakens the influence of speed on air resistance energy consumption by 59.1%, and its regulatory effect on air resistance energy consumption is stronger than that of friction energy consumption. (3) Energy conservation equation of moving vehicles is formed and coefficients’ physical significance is explained. The study provides a theoretical basis for the optimization and management of signalized intersections.
