摘要：Aiming at the problem that the complex intersections of the eco-city are not controlled by the short-term planning of smart traffic signals,leading to driving delays and causing serious traffic jams.Therefore,a short-term planning method for smart traffic signals in an ecological city based on the NS-BML model is proposed.We complete modeling with minimal or existing data,and predict traffic parameters.Based on the established model,we complete the design of vehicle acceleration and deceleration control laws,set open boundary and closed boundary parameter conditions,and optimize the allocation strategy of the short-term traffic signals.The Manhattan network is used to simulate traffic intersections,and the strategy process is designed to complete the research on the short-term planning method of traffic signals.The results of the simulation experiment show that,in the same simulation environment,the proposed method has a significant reduction in the delay time of the trunk line compared with the traditional planning method,and the average number of stoppages on the trunk line is also reduced by 0.87,which verifies that the designed planning method has a certain reliability.
