Transportation path planning method

The invention relates to a transportation path planning method, which selects more than three paths with similar distances and time through map software, takes a road condition safety value SRRC, a road traffic volume value SRTPI, a bridge safety value SRBrg, a tunnel safety value SRTun and a slope safety value SRSlp in the three paths as five factors influencing path traffic safety, and is characterized in that the five factors are endowed with weights; and a safety index value RSI of each path is comprehensively obtained, and the path is selected according to the safety index value RSI. In the path selection process, related road maintenance and regular inspection data, road traffic condition information and a safety evaluation result of a road project are used for quantitatively evaluating the influence of road conditions, traffic volume, bridges, tunnels, side slopes and other structures on path passage safety, and a safer and more reliable transportation path is provided. 一种运输路径规划方法，通过地图软件选择三条以上距离和时间相近的路
