Computing method and system of movement authority route

The invention discloses a computing method and system of a movement authority route. The problem that the time consumed when a radio block center (RBC) computes movement authority is long is solved. According to the technical scheme, when the radio block center computes movement authority, route search is executed only once, the highest possible movement authority route is preliminarily obtained,all static and dynamic parameters are checked according to the route, the length of the route is adjusted, finally, the size of movement authority messages is judged according to the serialization result, adjusting is carried out, and it is ensured that leagal and available movement authority is generated. 本发明公开了一种行车许可线路的计算方法和系统，解决无线闭塞中心(RBC)计算行车许可耗时较长的问题。其技术方案为：无线闭塞中心计算行车许可时，仅执行一次线路搜索，初步获得最大可能行车许可线路，并根据该线路检查所有的静态动态参数，调整线路长度，最后根据序列化结果判断行车许可消息大小并进行调整，确保生成合法可用的行车许可。
