| In order to solve the occupancy of the road capacity by the bus lanes and reduce the delay of bus driving,the intermittent bus lane is a more effective solution.With the development of intelligent networked vehicle technology in the future,vehicle-to-road communication technology is an important application.Under this premise,many scholars have proposed an intersection plan with the help of vehicle-to-road communication technology,which is called reserved intersection.The difference between signalized intersections is that the intersections under this scheme no longer have signal lights,but instead allow vehicles to pass by avoiding vehicle conflicts in the intersection.Most of the existing bus priority strategies are researched in the context of traditional signalized intersections.This article proposes a bus priority strategy,which is suitable for the setting background of intermittent bus lanes and reserved intersections.It is expected that in the future intelligent network connection Under the environment,it provides a new idea for public transport priority.The main tasks of this paper are:First,by consulting relevant domestic and foreign literature,starting from the intermittent bus lane theory,the reserved intersection strategy and the bus priority control strategy,the different bus priority strategies are compared and analyzed from the two aspects of space and time to find out each Existing advantages and disadvantages,the determination of intermittent bus lanes and reserved intersections in the intelligent network environment is the main control method for realizing bus priority in the text,which provides the basis and basis for the core content of this article.Secondly,for intermittent bus lanes,based on intelligent network technology,vehicle communication technology and induction control principles,the concept of bus priority detection range is proposed,the detection range setting and calculation method,and the setting method of reserved intersections are studied.On this basis,the overall control logic of the bus priority system is studied.The minimum vehicle delay is the objective function,and the time conflict for vehicles passing through the grid is the main constraint.The solution method is explained in order to give the bus a higher priority at the intersection.Finally,by setting up a certain number of buses and social vehicles to pass through the intersection,from four perspectives,from setting or not setting the bus detection range for conventional lanes,and setting and not setting the bus detection range for intermittent bus lanes,vehicle delays and passengers Per capita delay is the evaluation index.The strategy proposed in the text is evaluated.The results show that this strategy can greatly reduce bus delays without increasing the per capita delay of passengers,thus verifying the effectiveness of the strategy. |
