【Abstract】 Aiming at the serious congestion problem at the intersection of Sheshan Road and Dongjiayao road along the Qingshan South Road in main road of Nanchang,the improvement measures to prohibit left management at intersection are put forward. Combined with the traffic background conditions of Qingshan South Road and the surrounding concrete road,the feasibility and influence of the implementation of the measures are qualitatively analyzed,and the effect of the improvement measures is quantitatively evaluated by using the delay model of transition function. It is feasible to adopt the forbidden left management measures in the north entrance of Qingshan South Road and Sheshan Road intersection.The traffic condition of Qingshan south road can be obviously improved,and the effect is good after implementation.更多还原
