Multi-indicator Road Traffic State Assessment Based on Path State

Abstract

In order to evaluate the traffic condition of urban road, the article makes an actual modeling of the urban road junctions and the analysis of the status of sub-lanes. Combined with various impedance factors of the road network, in this paper, a state coefficient matrix is used to represent the road network impedance data, and a road traffic status assessment system based on the actual path status with multi-parameter indexes is proposed. The evaluation system is improved based on the existing state assessment methods and breakthroughs in the assessment mode. In the past, it only estimated the overall traffic condition at the intersection; the evaluation method was more efficient and the evaluation result was more accurate. The actual road network in Shijingshan District is used to verify the results. The results show that the algorithm is effective.
