In order to solve the problem that it is difficult to define the restricted area of automobile tail number in mountainous-city, relying on the large traffic data of the main urban area and on the basis of multi-source data fusion, taking the average running speed of road network, peak traffic index, congestion mileage, reduction of traffic flow and difficulty of implementation as evaluation indexes, this paper establishes the restricted area of automobile tail number in urban areas. The implementation effect evaluation model quantitatively evaluates the implementation effect of regional traffic restriction, bridge traffic restriction, tunnel traffic restriction and so on. It is verified by an example in Chongqing main urban area. The results show that under the same restriction intensity, the overall effect of bridge traffic restriction is better than tunnel traffic restriction and regional traffic restriction, which has better practicability.
