In order to meet the increasing aesthetic needs of the public, improve the integration of traffic planning and urban planning, facilitate traffic simulation data analysis and effect display, and facilitate traffic planning scheme evaluation, this paper is based on cesium to develop a three-dimensional simulation platform for urban traffic, design Celestia came out, and based on common simulation software such as sumo, Paramics, Vissim, and used Python and JavaScript language to design and develop a web page simulation platform to display the 3D effect of road traffic simulation for users, and added a lot to improve the simulation effect, which is convenient for users. Functions to evaluate simulation effects. Users only need to open the website, upload the simulation file or select the map area in the map link box, select the simulation parameter requirements, and wait for the data to be read in the background to get an interactive 3D traffic simulation. This work with convenient operation, powerful function and broad development space largely fills the blank of domestic road traffic 3D simulation. Experiments show that when the number of divisions reaches 15, the resolution is 0.037m (within 5 cm), which can meet most practical needs.
