With the development of cities and the application of ITS technologies, methods can give more accurate results of traffic assignment by considering both travel costs through road links and signal delays at intersections. These methods are needed in urban traffic planning and management. Practical signal control policy and delay models are introduced in the traditional user equilibrium assignment model. Also, a new asymmetric network user equilibrium model is proposed. An arc-labeling algorithm is used instead of the classic node-labeling algorithm in searching the shortest paths. General procedures to solve the problem are presented and the model is solved by a diagonalization algorithm. Finally, the numerical analysis showed that it is significant to include the signal delay in urban traffic assignment, and the developed algorithm has good performance on solving this problem.
