Study on the Relationship between Urban Road Network Service Level and Capacity

摘要

By analyzing evaluation indicators of the sections service level and the intersection service level, and using traffic flow theory to convert the different evaluation indicators, this research gave a unified service level indicator, referred to domestic and international experience, and presented a division way of the road network service level. According to the concept of time-space consumption, this research also created a road network capacity model under the constraint of service level. In addition, this research gave a numerical example to test the road network relational model of road network service level and capacity.
