Abstract:Based on the genetic algorithm idea,a new illumination optimization algorithm is proposed aiming at dynamic traffic assignment.This new algorithm overcomes the disadvantages of premature convergence in simple genetic algorithm and enhances the ability of global searching by using the modification of the selection operator,crossover operator and mutation operator and the adoption of the termination condition of simulated annealing.The computer simulation results show that this algorithm is fast and efficient and improve the dynamic traffic assignment model's practicality a lot.
Keywords:improved genetic algorithm  dynamic traffic assignment  simulated optimization  dynamic users equilibrium
