摘　　要：根据粗糙集及合理变权理论确定公交线网中节点的重要度,进而确定线路的重要度。以单位里程的路线重要度最大为目标,以单条公交线路的长度为约束条件,生成公交初始网络,采用Black-Scholes模型对初始网络进行投资的实物期权评价,判定网络是否可行,并根据线路重要度确定城镇公交线路的建设实施顺序。以江苏省吴江市干线公交线路的布设为例,得出规划的干线公交线路331 km及公交线路的建设实施顺序。Based on rough set theory and reasonable variable weight theory determine the node im-portant degree and the line of importance.With the unit mileage route importance as a goal,a single line as the constraint conditions,the initial bus network can be generated.With the Black-Scholes model,we can simulate the initial network of real option evaluation and determine the feasibility of the network.Ac-cording to the route importance determine the construction sorting of urban bus lines.The method is ap-plied to the main road network in wujiang city of jiangsu province,we can caculate the construction sor-ting and planning main road network 331 km.
