Abstract

The disclosed ambiguous path recognition system comprises: a road-side antenna device to continual send RF signal with path label information, a table read-write machine to read path information, and a vehicle-carry unit with an IC card to record vehicle path information and a receive and store device for former label information. This invention saves investment, has high reliability, and fit to spread on freeway.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a path identification system and method suitable for a highway toll system. Background technique [0002] Network toll collection is the main development trend of expressway toll collection methods. Basically, all developed regions have implemented expressway network toll collection systems based on IC cards. In the networked toll collection system, accurate account splitting and settlement is the key to ensuring the interests of expressway owners, and complete and clear driving route data is the basis for accurate account splitting. At present, the highway network is becoming more and more developed. In the same road network, starting from the same starting point and arriving at the same destination, there are many different paths (ambiguous paths) to choose from, but the current toll system can only identify the starting point Information and destination...
