Embodiment 1

[0041] The urban road traffic bus priority signal control method of the present invention, at the intersection Install RFID base station type directional reader at 40-200 meters, and install active electronic tags on the bus. When the bus approaches the intersection, the active electronic tag on the vehicle and the RFID base station type directional reader installed at the intersection Response, the RFID base station directional reader signal interacts with the traffic signal control system of the traffic command center, through the traffic signal control system and the traffic signal machine to control the change of the traffic lights at the intersection, and realize the bus priority traffic control: 1) Extend the green light time (green extension) or extended priority (priority extension): When the green light at the intersection is about to end, if the RFID base station directional reader detects that there are still buses passing the intersection, the green light time in t...

Embodiment 2

[0044] see figure 1 , figure 2 . The urban road traffic bus priority signal control method of the present embodiment is characterized in that: the green light prolongs the time, and judges according to the distance between the RFID base station type directional reader installation position of response and the stop line by the traffic signal control system; When a bus arrives at the tail end of the green light phase, the green light time is extended until the bus vehicle passes the intersection.

Embodiment 3

[0046] see figure 1 , figure 2 , image 3 . The urban road traffic bus priority signal control method of the present embodiment is further different from embodiment 2 in that: as image 3 As shown, through the detectors installed at traffic intersections (there are many kinds of detectors, in addition to card readers, induction coils can also be used), detect the traffic flow signal at the intersection, the queue length of vehicles and the lane occupancy signal, and then Using the rule-based bus priority algorithm model, according to the bus queue length, lane occupancy rate, traffic volume, set the flow adjustment range, and determine the green light extension time according to formula (1)

[0047] w=f(a)*a1+f1(d)*d1+b-c (1)

[0048] In the formula, w is the extension time of the green light, f Represents a linear relationship; a is the traffic adjustment range parameter, d is the lane occupancy adjustment range parameter, a1 and d1 are the adjustment weights, c is the ...

Abstract

The invention relates to a bus priority signal control method. The urban road traffic bus priority signal control method is that oriented reader-writers are installed at the crossroads, active electronic tags are installed in buses, and when the buses run close to the crossroads, the oriented reader-writers and the active electronic tags in buses act in cooperation with each other, interact with a traffic signal control system in a traffic command center and perform bus passing priority control by controlling traffic signal lamps at the crossroads: (1) green lamp time prolonging: when green lamps at the crossroads are about to change, the green lamp time in the advancing direction is prolonged to enable the buses about to arrive to pass the crossroads; (2) read lamp time breaking or calling for passing priority: after the current green lamp phase waits for the shortest green lamp time, existing red lamps are switched instantly for the buses arrived at a red lamp phase, bus priority green lamps are turned on in advance for bus passing. By adopting the urban road traffic bus priority signal control method, the bus operation speed can be effectively improved, the bus line travel time is reduced practically, and overall influence on other traffic flows is small.

Description

technical field [0001] The invention relates to a method for controlling urban public traffic signals, in particular to a method for controlling public traffic priority signals. Background technique [0002] Urban roads are the carriers of traffic flow, and their transportation efficiency largely determines people's travel choices. my country's "Outline of the Twelfth Five-Year Plan for National Economic and Social Development" clarifies "implementing the strategy of giving priority to the development of public transportation and vigorously developing the urban public transportation system", and proposes to incorporate "full coverage of public transportation in urban built-up areas" into the national basic In the public service system, for the first time, the public transport priority development strategy has been upgraded to a national strategy. [0003] Due to the large passenger capacity of public transport vehicles and the small passenger capacity of social vehicles, it ...
