The Degree of Complexity for a Separate Intersection and a Road Network

To analyze the operational performance of urban intersections, the degree of complexity was studied for a separate intersection and a road network. Conflict points and the probability of conflict were selected as two parameters, the model of degree of complexity for a separate intersection was developed, and specifications for parameters were provided. Then the study range was extended to the road network: a model of degree of complexity for road network under different density was constructed. Through an example, the model shows that the degree of complexity for a separate intersection increases with the number of lanes and that road network varies little when the volume for single lane is fixed. The results indicate that a high-density road network is more feasible for decreasing traffic conflict, which can be applied to transportation planning.
