A political adviser is suggesting an electronic license plate system for vehicles to help relieve Beijing's traffic problems.

The system would collect real-time data location information of the vehicles, Zhu Liang said at the ongoing session of the 12th Beijing Municipal Committee of the Chinese People's Political Consultative Conference.

Every month, each vehicle would be given a quota of traffic it could pass on busy roads during rush hours. When the quota is filled, the driver will have to pay an additional fee to continue using busy roads, he said.
