The Research Is Based on Dynamic Optimization Traffic
Patrol Service Platform Setting And Scheduling
Abstract:The dynamic optimization problem of the setting and scheduling traffic patrol service platfrom is studied in this article,the Floyd algorithm is used to calculate the shortest distance between any two points which are in the transport network and the traffic patrolimportant transport gateway service platform.At an example of Chongqing city, the dynamic optimization model is established by the data analysised. Then the rationality of the service platform setted up is analysised by observing the scatterplot of the traffic patrollocation service platform and the corresponding accident ratings and the coordinate recognizer . Considering increasing or resetting traffic patrol service platform comes to the reasonably configuration scheme. Results show that the established model is scientific and reasonable, which has a certain guiding significance for setting and scheduling traffic patrol service platform.
