Vehicle infrastructure cooperative-based bus real-time dispatching and priority control method

Abstract

The invention discloses a vehicle infrastructure cooperative-based bus real-time dispatching and priority control method. In view of a bus line, in an up direction or a down direction, firstly, basedon the vehicle infrastructure cooperative environment, the position information of each intersection, each stop and each bus, the driving speed of a bus and the signal timing scheme of an intersectionin a research road section are acquired and inputted; the signal delay of a bus at an intersection is then calculated, the headway of adjacent buses is calculated, and fast and slow attributes of a bus are judged; and finally, with the difference between the headways of all adjacent buses and an expected headway in the whole bus line to be the minimum as an objective function, a function relationbetween the headway and the bus speed, the stop time and the signal timing scheme is built, and a bus real-time dispatching and priority control model and method are put forward. The method is mainlyused to alleviate the problem of mutual cluster between buses in the same line, and the bus service level and the reliability are improved.

Description

technical field [0001] The invention belongs to the fields of traffic transportation and traffic information engineering and control, and relates to the fields of public traffic dispatching and bus priority, and more specifically, relates to a method for real-time bus dispatching and priority control based on vehicle-road coordination. Background technique [0002] Vigorously developing public transportation has become a basic policy for the development of urban transportation in my country. Driven by the public transportation priority strategy, the urban bus transportation (referred to as "bus") system is gradually becoming an important choice for urban commuting transportation. However, many uncertainties, such as red light signals at intersections lead to bus delays and increased travel time volatility, which in turn lead to low speed and unreliability of the entire line and even the entire bus corridor system, which has a negative impact on the service level and quality o...

AI Technical Summary

Problems solved by technology

[0007] It can be seen that the existing research on bus online scheduling ignores or simplifies the impact of signal lights and bus priority on bus scheduling; the research on bus priority lacks the integration with the overall operation status of bus lines and online scheduling.
