Rational delineation of traffic restriction zones,complemented by differentiated traffic demand management policies can alleviate urban congestion and improve urban traffic management.Using real-time traffic congestion index,OSM road network data,bus line and station data,we identify the distribution of congestion zones within the graded traffic restriction zones in Hangzhou,analyze the traffic supply characteristics of congestion zones,classify the types of congestion zones,and propose classification control optimization strategies.It is found that the traffic restriction zones in Hangzhou are reasonably divided.The road network density and its grade configuration are reasonable in the congestion zones with restricted traffic for vehicles with Zhejiang A and regional plates,but the public transportation supply in those areas is slightly misplaced and insufficient.The road network supply is insufficient in the congestion zones with restricted traffic for other provinces'vehicles,and the level of public transportation supply is relatively high.However,there are problems of misalignment of transportation supply elements and insufficient alternative public transportation at a fine scale.According to the traffic supply characteristics of the congestion zones,they are divided into area-type,enclave-type and node-type congestion zones.We propose strategies such as implementing congestion charging,optimizing road network structure,improving micro-circulation capacity,adding bus routes to string points into lines and guiding bus travel,to provide a reference for the refined traffic management of large cities.
