路侧节点部署的几种典型场景研究

s an infrastructure in the intelligent traffic guidance system, network nodes deployment will directly affect the dynamic induction algorithms, high-speed vehicle positioning performance indicators, while also controlling costs reasonably closely. In order to meet the communication coverage under the maximum deployment cost savings, this paper is to achieve complete coverage of the minimum connectivity node deployment. First, the paper gives the architecture model of the entire road-side node deployment. On this basis, then, for a single bilateral deploy an ordinary road, the paper respectively achieves the calculation of full coverage of communication nodes required minimum, given specific deployment scenarios. Finally, the different scenarios, such as ordinary roads, ramps, main roads, crossroads of deployment scenarios analyzed in detail.Simulation experiments are carried out on several schemes of common road node deployment. When the width is 30m, both deployment node spacing is 25.6% higher than unilateral, the required number of nodes is reduced by about 20%.
