Abstract: In order to research the offset optimization method of trunk road signal coordinated control,the traffic flow models closer to actual vehicle motion state and the signal coordinated control optimization models of an urban trunk road were constructed, based on cell transmission model ( CTM) . With the help of the immune genetic algorithm ( IGA) ,the offset optimization method of two-way trunk road signal coordinated was put forward. Through the simulation experimental platform estbalished by MATALB 7. 0 programming,the models and optimization methods were verified. Research results show that the average vehicle delay obtained by the optimization method reduces by 26. 2% and 17. 3% respectively,compared with those got by the traditional graphic solution and numeric solution methods.

Key words: traffic engineering, offset, optimization method, cell transmission model ( CTM) , trunk road coordinated control; immune genetic algorithm
