英文摘要：

According to the traffic control optimization problem of urban trunk line and the surrounding area,the optimization model and algorithm of main city area traffic control based on Q-algorithm is put forward. First of all,the traffic control issue of urban artery line was analyzed,and the corresponding control model was established by taking the designer＇s traffic control strategy into account. Then the main city area traffic control oriented optimization algorithm and steps were presented based on the Q-algorithm theory. Finally,traffic control simulation verification was carried out at the background of Changsha city main area. The simulation results show that this model can effectively improve the efficiency of urban arterial traffic,reduce traffic delays on the main line and stop rate of vehicles,which has strong practical significance.
