Gipps model is a typical car-following model based on safe distance and is widely used in computer simulation. However, in order to avoid collision with the preceding vehicle, the model has strict restrictions on the following spacing, that makes the model has a certain error at the simulation of vehicle space headway in complex traffic environment. Due to that, based on the mathematical expression of the following spacing in Gipps model, this paper proposes a method of adding influence coefficient to improve the simulation accuracy of space headway. Furthermore, the effectiveness of the method is proved by simulation experiments, and the experimental results illustrate that the simulation results of the improved model are closer to the field data in complex traffic environment than the original model.
