A very promising direction in intelligent transportation system is the applications based on vehicular ad-hoc networks (VANET). VANET of a country is one of the most importation indicators of its economic growth. In this paper, we analysed the characteristics of VANET network topology using complex network theory. The author contribute VANET model, analyse the statistical properties of complex network based on the degree distribution, the clustering coefficient, the average path length and find that the network has scale-free and small world features. The structure and properties of VANET have great implications for traffic congestion and urban planning. The robustness analysis indicates that VANET is robust to random attack when considering static robustness, but somewhat vulnerable to intentional attack.
