ELECTRONIC TOLL MAP

摘要

The invention discloses electronic toll map containing a multitude of virtual toll stations covering the entire toll area, where each one of the multitude of virtual toll stations contains one or several geographic areas, which are arbitrary polygons, where the toll map is being defined as a tree structure consisting of cells defined as rectangles with exact coordinates and sides parallel to meridians and parallels of latitude, where the data quantity in a cell is less than the OBU memory capacity, where each cell contains all toll stations and geographic areas which are at least partially within the area a cell covers, where the toll charge accounts for only those cells that represent leaves of the tree structure. The invention provides for minimum exchange of data between the MD and the OBU relieving the communication channel and consequently the costs and updating time.
