实现OSM真实地图适配于微观交通仿真引擎的转换方法

By identifying nodes and road patterns in the OSM map, road merging and intersection calculations are performed. The GEKKO method, Newton's method, and secant method are used to solve the nonlinear equations and fit the road connection points. This solves the problem of lack of simulation accuracy in the microscopic traffic simulation engine and realizes the visualization and simulation of the real road network.
