- Abstract:
- The traffic conditions would change when vehicles move under vehicular ad hoc networks (VANET). Then change of network connection was triggered which led to the adjustment of moving mode for related vehicles. In order to better investigate the actual vehicle moving trace, key factors influencing vehicle moving mode including mobile constraints, traffic environment and time scale were analyzed from the perspectives of vehicle, traffic situation and driver to provide a reference for the establishment of the model. Then the research development, representative research achievement and related literatures of the mobility model were reviewed according to the mathematical theory method. Four types of models including traffic wave model, car following model, cellular automation and behavioral model were presented. In order to generate a model truly reflecting the real estate, actual data were adopted to verify and modify the theoretical model. Based on the method, mobility model was divided in detail by the selected related data of users and vehicle track, and the application of the method to the aspects such as real-time situations of physical environment, vehicles interaction, behaviors of users, real-time situation reflection for traffic flow and prediction for future traffic flow trend. The results show that the capability and driving behavior characteristics are less considered which leads to the neglect of the influence of mobility model on driver’s personal characteristics, therefore the applicability of the model will be affected. How to enhance the interaction between network emulator and vehicular mobility model, discover feature application field to achieve the optimal match among users, vehicle and traffic environment are the research focus for vehicular mobility model. The prediction of the development trend of the model provides a reference for scholars in choosing correct architecture module and appropriate simulation particle size.
