The Intelligent Transportation Systems(ITS)can more easily obtain the status information of sur-rounding traffic and better control the movement of vehicles. In order to describe and predict the behavior of vehi-cles in traffic flow under the ITS environment, ensure safety to the vehicle, and increase the stability of traffic flow, the paper considers the two factors of the front distance memory of the vehicle in the ITS environment. A new type of vehicle queue based on the dual-speed difference between the front and rear vehicles follows the model(HMBE). By conducting linear stability analysis on the HMBE model, the linear stability conditions of the HMBE model have been obtained, and it was verified that the two factors of the front distance memory and backward observation can enhance the stability of traffic flow, improve vehicle safety and traffic efficiency. Through the numerical simulation analysis of the impact of small disturbances on traffic flow, it was found that as time increases, the small disturbanc-es almost disappear, verifying that the HMBE model has a more significant effect on improving traffic flow stability compared to the general dual speed difference model.
