Problems solved by technology

[0003] Although some studies have found that bus priority will also bring many problems, such as bus overflow, the overall operating efficiency of the intersection will be greatly reduced, and bus priority will increase negative factors such as delays and parking times for social vehicles
However, few scholars have proposed an effective bus priority control method that can improve the efficiency of bus operation without causing negative impacts on social vehicles.

Embodiment 1

[0049] Set multiple detectors at an intersection, the layout of the detectors is as follows figure 2 As shown in , wherein, the first detector 1 is used for counting and recording the situation of the bus leaving the station, the second detector 2 is used for detecting whether the last bus parking space is occupied, and the third detector 3 is used for detecting waiting to enter the first bus parking space. Whether the bus at a stop is full of roads and overflows, the fourth detector 4 is located at whether the bus drives to the stop line, and the fifth detector 5 is used to detect the arrival of the bus.

[0050] figure 1 For the overflow control core logic flow of this embodiment, figure 1 Among them, BRi indicates that the signal light in the running direction of No. 111 bus 7 is a green light signal, iONS indicates that bus 7 of No. 111 arrives at stop 6 on time, iLa indicates that bus 7 of No. 111 arrives at stop 6 late, and iLO indicates that bus 7 of No. 111 arrives a...

Embodiment 2

[0080] The significant difference between this embodiment and Embodiment 1 is that in this embodiment, three detectors are arranged at a certain intersection, such as image 3 , wherein the sixth detector is used to detect whether there is a vacancy at the bus stop 6, the third detector 3 is used to detect whether the bus waiting to enter the first bus stop is full of roads and overflows, and the fifth detector 5 is used for Detect bus arrivals.

[0081] Based on the above-mentioned equipment, a kind of intersection bus stop overflow control method of the present invention is used to control, comprising steps:

[0082] A. When the No. 111 bus 7 that needs to enter the first stop 6 is approaching the intersection, that is, when it is captured by the fifth detector, whether the signal light in the direction of travel of the No. 111 bus 7 is a green light, and if yes, then Execute step B, if not, end overflow control;

[0083] B. Determine whether the 111 bus 7 is on time, if y...

Embodiment 3

[0112] The similarities between this embodiment and the second embodiment will not be described, and only the differences will be described.

[0113] The significant difference between the present embodiment and the second embodiment is that in the present embodiment, after the overflow control of the docking station 6 is completed, for example image 3 Intermediate stop 9 carries out overflow control.

Abstract

The invention relates to an intersection bus stop overflow control method. A bus stop is located behind an intersection. The method comprises the steps that A, when a bus travels nearby the intersection, whether a signal light in the advancing direction of the bus is green or not is judged, if yes, step B is carried out, and if not, overflow control is ended; B, whether the bus is punctual or not is judged, if yes, step C is carried out, and if not, step D is carried out; C, whether the bus stop which the bus is about to arrive in is in overflow or not is judged, if yes, the step D is carried out, and if not, overflow control is ended; D, a green light signal in the advancing direction of the bus is cut off. Compared with the prior art, the intersection bus stop overflow control method has the advantages of improving the traffic operation efficiency at the intersection and the like.

Description

technical field [0001] The invention relates to a method for controlling the overflow of a bus stop, in particular to a method for controlling the overflow of a bus stop at an intersection. Background technique [0002] Nowadays, at many signalized intersections, the bus signal control mostly adopts the bus priority control method, which may specifically include extending the green light, early breaking the red light, and interpolating phases. A lot of research has been done on the control strategy of public transport priority at home and abroad. On the one hand, the use of public transport priority at intersections will improve the operating efficiency of public transport, but on the other hand, it will also have a certain negative impact on the operation of social vehicles. Since the intersection delay accounts for 15%-20% of the bus travel time, the implementation of bus priority at the intersection can reduce the bus travel time and improve its service level. However, i...
