Application of traffic flow assignment model in the actual network

In order to apply the traditional traffic assignment model in the actual network, firstly this paper distinguishes the impact of intersection delay between different steering on traffic assignment by changing the topology of network. Secondly this paper presents a modified dijkstra algorithm based on the changed topology of network and presents a modified traffic assignment algorithm based on the modified dijkstra algorithm. Lastly this paper gets the result of traffic flow assignment by employing Matlab based on the modified traffic assignment algorithm. The result shows that the proposed algorithms are feasible.
