Finally, a traffic impact assessment was carried out according to the relevant regulations, and proposed relevant improvement measures for each specific problem.4 PTV VISION SOFTWARE SUITE Network modelling large scale, national, regional and local transport network developments and demand modelling Detailed microscopic modelling of individual vehicles covering all modes of transport multi-modal micro-simulation Advanced microscopic pedestrian simulation, both inside and outside buildings A solution for all traffic analysis needs Real-time traffic simulation model, based on offline strategic model (PTV Visum), fused with real-time data Interconnected Online traffic signal adaptive network control model-basedĥ MODELS ARE DATA HUNGRY Junction info (e.g. On the basis of the data obtained from the survey, TransCAD software was used in the estimation of The OD matrix to predict the background traffic, and then superimposed the traffic volume to obtain the traffic assignment result. After determining the study area, the traffic flow of each intersection within the scope of the study was counted, and the specific conditions of the roads involved were investigated.

This article first determined the basic parameters of the traffic impact assessment. It aims to test the interaction degree of various traffic and discuss whether the new contradictions and the negative effect of traffic are brought. Traffic impact assessment is to evaluate the potential effects of a particular development on the traffic network in the affected area. Advances in Intelligent Systems and Computing
