Intelligent traffic system
First Claim
1. An intelligent traffic system, at least comprising a traffic control center, a traffic information service center, a cellular mobile communication system, a road toll collection system and an in-vehicle terminal, characterized in that the traffic control center, the traffic information service center, the cellular mobile communication system, and the road toll collection system are connected to each other via a wired communication network;
- the traffic control center communicates with the in-vehicle terminal via the cellular mobile communication system, to send instructions and information to the in-vehicle terminal and receive the intrinsic information and the dynamic information of the vehicle provided by the in-vehicle terminal;
the road toll collection system communicates with the in-vehicle terminal via the cellular mobile communication system to perform toll settlement; and
the traffic information service center communicates with the in-vehicle terminal via the cellular mobile communication system.

Abstract
The present invention discloses an intelligent traffic system. The system at least comprises a traffic control center, a traffic information service center, a cellular mobile communication system, a road toll collection system and an in-vehicle terminal, which are connected with each other via a wired communication network. The in-vehicle terminal communicates with the traffic control center, the road toll collection system and the traffic information service center respectively via the cellular mobile communication system. The present invention further claims an in-vehicle terminal used in an intelligent traffic system and a method for realizing an intelligent traffic system with a cellular mobile communication system. By adopting the intelligent traffic system, its construction cost will be reduced greatly.
