This paper proposes a new data link routing protocol, which realizes more efficient transmitting of video information and meets the requirement of traffic organization and data collection. It takes the traffic circumstance into consideration and synthesizes the two classic protocols, LEACH and PEGASIS. In order to realize the visual management of the traffic network, we allocate sensors along the roads, so as to introduce a link configuration. We also consider the usage of cluster for time saving. This paper focuses on the comparison of the three protocols, LEACH, PEGASIS and the newly proposed algorithm. The simulation results indicate that our algorithm is much better than LEACH in power consumption and smarter than PEGASIS in network latency. Furthermore, the data collected by applying this protocol are the most suitable for the further work in ITS data analysis
