摘要：In this presentation, we first use the generalized car-following model to explore thecommuter’s trip cost and its corresponding traffic properties on an open road at the equilibrium state from the analytical perspective, and then use the full velocity difference model (Jiang et al., 2001) to testify the analytical results and the corresponding traffic properties from the numerical perspective. The numerical results are qualitatively consistent with the analytical results and the reality, which show that we can use car-following model to study each commuter’strip cost at the equilibrium state.In addition, we can obtain the following results: a) each commuter’s time headway time at the origin under the equilibrium state (it is an endogenous variable) can be fitted by a function, which shows that each commuter’s time headway at the origin can be defined as an exogenous variable; b) each commuter’s arrival time and time gap at the destination, early arrival time, and trip cost under the fitted time headway are almost the same as those under the time headway calculated based on the equilibrium condition, which just illustrates that the traffic flow under the fitted time headway has approximately reached the corresponding equilibrium state. Finally, we further study the evolution of traffic flow under three traffic states (i.e., the number of commuters is very small, moderate and very high) and find that the evolution of traffic flow is related to the number of commuters.
