The invention discloses a road network traffic ecological cost quantification-oriented vehicle microcosmic kinematics model construction method. The method comprises the following steps: 1) establishing a road section vehicle microcosmic motion representation system; 2) dividing functional fragments of space resources of road sections between adjacent intersections; 3) modeling car following behaviors among vehicles in different functional segments; (4) modeling transverse lane changing behaviors among vehicles in an interlaced lane changing area; 5) vehicle intersection driving decision modeling; and 6) second-level calculation of the road section traffic ecological cost: calculating second-level instantaneous working condition parameters in the vehicle running process as parameter input to calculate the road network traffic ecological cost. According to the method, the problem that an objective function of an optimization method oriented to ecology in the field of traffic control and management cannot be recognized and calculated is well solved, and a high-precision and high-reliability metering method for microscopic traffic flow delay, emission and energy consumption based on an operation sequential chain is further provided. Microcosmic behaviors such as driving action feedback response and the like of vehicles in a road network are quantified.
