Analysis and improvement of vehicle information sharing networks

Based on large-scale mobile phone data, mobility demand was estimated and locations of vehicles were inferred in the Boston area. Using the spatial distribution of vehicles, we analyze the vehicle information sharing network generated by the vehicle-to-vehicle (V2V) communications. Although a giant vehicle cluster is observed, the coverage and the efficiency of the information sharing network remain limited. Consequently, we propose a method to extend the information sharing network’s coverage by adding long-range connections between targeted vehicle clusters. Furthermore, we employ the optimal design strategy discovered in square lattice to improve the efficiency of the vehicle information sharing network. •Analysis of vehicle information sharing network using realistic travel demand.•Extend information coverage by adding only a few long-range connections.•Optimal design strategy is employed to improve efficiency of information transmission.
