Abstract: In order to  improve efficiency of road traffic, by using  the minimum traffic navigation  cloud sacle  given number of road nodes and vehicles, we  proposed a performance analysis model based on target map and cloud center related parameters. Firstly, we analyzed  the target map and the relevant parameters of the cloud platform that affected  navigation performance.  Secondly, we  considered the number of road nodes and vehicles, as well as virtual machines of  different scales and frequencies, and conducted three sets of experiments.  Finally, we  verified the effectiveness  of the model by using real datasets. The experimental results show that the proposed performance analysis model can accurately calculate the minimum scale of  navigation cloud that satisfies the constraint conditions.
