Vehicle controlling method for guaranteeing public transport vehicle priority passing

Abstract

The invention discloses a vehicle controlling method for guaranteeing public transport vehicle priority passing. The vehicle controlling method comprises the following steps: step 10) collecting traffic flow data of a crossing, road information and public transport vehicle running information; step 20) laying a road surface; step 30) determining an initial signal timing plan; step 40) measuring and calculating compressible green light signal duration of each signal phase; step 50) monitoring an operation state of a public transport vehicle in real time; step 60) judging whether the public transport vehicle priorly passes is needed, if so, entering step 70), and if not, entering step 80); step 70) responding a public transport vehicle priority passing request; step 80) judging and processing other public transport vehicle priority passing requests; and step 90) at the moment, returning to step 50), monitoring the operation state of the public transport vehicle; and at the moment, public transport vehicle priority passing control on the crossing is finished. With the adoption of the vehicle controlling method, the public transport vehicle can be enabled to priorly pass the crossing to a large extent, and the running efficiency of a public transport vehicle system and the going out efficiency of passengers are promoted.

Description

technical field [0001] The invention relates to a signal control technology and an urban public transport priority technology, in particular to a vehicle control method for ensuring priority passage of public transport vehicles. Background technique [0002] At this stage, my country's huge urban traffic demand and the overall relatively backward traffic system and traffic structure have formed a sharp contradiction. Urban traffic congestion and its accompanying environmental pollution and safety issues have attracted widespread attention from the entire society. During the peak hours of commuting, long-term and normal traffic congestion at many important traffic nodes restricts the rapid development of the urban economy. The public transportation system has the advantages of large carrying capacity, high transportation efficiency, low energy consumption, relatively little pollution, and low transportation cost. Therefore, the development of public transportation is the firs...

[0003] However, in the actual application of bus signal priority control, bus priority signals are often only designed for bus lines in one main direction (generally speaking, straight bus lines are the main ones), and seldom or even directly ignore the impact of different steering bus lines on bus lines. Conflict of Priority Signaling Requirements

Although this method of only considering the main direction and ignoring the priority needs of other shifting bus lines reduces the difficulty of implementing bus priority and makes it more operable, there are a large number of differences in the actual operation of many urban bus systems. Turning to the situation where the bus lines are collinear, so this kind of bus signal priority processing method cannot well deal with the current more complex bus operation conditions

At the same time, this ignorance of priority requests for bus lines in secondary directions sacrifices part of the interests of the bus system, so it is difficult to achieve the optimal effect of a win-win situation for the system. The overall efficiency of the system is not enough

Moreover, when the bus in the secondary direction enters the intersection before the bus in the main direction, even if the signal is a bus priority signal, all buses will not be able to enjoy the bus priority because of the blocking of the vehicle in front, which reduces the Prioritize the overall operating efficiency of the system
