Detailed Description
The core of the invention is to provide an optimization method for releasing public transport vehicles and related components, which can ensure that no public transport vehicle can enter a buffer area road section when the buffer area road section is occupied by controlling a special traffic signal indicator lamp, and avoid the influence on the passage of other vehicles at a road junction caused by queuing of a plurality of public transport vehicles in the buffer area road section.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of an optimization method for releasing public transportation vehicles according to the present invention, each public transportation vehicle is provided with a corresponding number, and a common platform includes a preset number of parking spaces;
the method comprises the following steps:
s11: judging whether a buffer area road section is occupied by public transport vehicles or not, wherein the buffer area road section is a road section between an intersection in the direction of driving into a common platform and the common platform;
referring to fig. 2, fig. 2 is a schematic view of a relationship between an intersection and a shared platform according to the present invention, taking a vehicle driving to the right as an example, a platform 1 and a platform 2 in fig. 2 are shared platforms, a public transportation vehicle can only stop at the platform 1 when entering a road shown in fig. 2 from the intersection 1, and can only stop at the platform 2 when entering the road shown in fig. 2 from the intersection 2, and the platform 1 and the platform 2 are respectively provided with only four parking spaces.
In the application, the applicant considers that only a limited number of parking spaces may be arranged in the shared platform, but if a plurality of public transport vehicles want to stop in the shared platform at the same time for getting on and off, the parking spaces may be full, and other public transport vehicles queue outside the platform, so that the intersection traffic entering the direction of the shared platform is influenced by the queued public transport vehicles, and the efficiency is reduced.
In order to solve the above technical problems, in the present application, a road section between an intersection driving into a direction of a common platform and the common platform is set as a buffer section, please refer to fig. 3 and fig. 4, fig. 3 is a schematic diagram of a buffer section corresponding to a platform 1 according to the present invention, fig. 4 is a schematic diagram of a buffer section corresponding to a platform 2 according to the present invention, a bus driving into the intersection passes through the buffer section before entering a station, therefore, if the number of buses entering the common platform at the same time is large, the bus will be queued at the buffer section first, if the buffer section is occupied, the bus can only be queued at the intersection, therefore, in the present application, it is determined whether the buffer section is occupied first, if the buffer section is occupied, the bus cannot drive through the intersection any more, if the road section of the buffer area is not occupied, the public transport vehicles can drive through the intersection, and the bus can be queued in the buffer area even if the parking spaces are occupied.
S12: if the buffer area road section is occupied by the public transport vehicles, a special traffic signal indicating lamp which is positioned at the intersection and indicates the passing of the public transport vehicles is controlled to display a passing prohibition signal;
in this embodiment, when the buffer area is occupied, in order to prevent other public transportation vehicles from driving into the shared platform, the control of the special traffic signal indicator lamp at the intersection is displayed as the passing prohibition signal, for example, the special traffic signal indicator lamp is displayed as the red light to prohibit the public transportation vehicles from driving through the intersection.
S13: if the buffer area road section is not occupied by the public transport vehicles, determining the occupation condition of each parking space in the shared platform, namely the serial number of the public transport vehicles which are going to pass through the intersection, and determining the length of the buffer area road section;
s14: judging whether the public transport vehicles passing through the intersection can completely enter the buffer area road section or not based on the occupation condition of each parking space in the shared platform, the number of the public transport vehicles passing through the intersection and the length of the buffer area road section;
s15: and if the buffer zone section can be completely accessed, controlling the special traffic signal indicator lamp to display a permission signal.
Since the public transportation vehicles comprise a plurality of types, the lengths of different types of public transportation vehicles may be different, and therefore, some public transportation vehicles only need to occupy one parking space in the shared platform, but when the length of the public transportation vehicle exceeds the length of one parking space, the public transportation vehicle needs to occupy two or more parking spaces, and the lengths of different buffer area sections are different, therefore, in the embodiment, before the public transportation vehicle passes through the intersection, the length of the public transportation vehicle is determined according to the number of the public transportation vehicles which are about to pass through the intersection, the length of the buffer area section is determined, the number of the idle parking spaces which are nearest to the buffer area section is determined according to the occupation situation of each parking space in the shared platform, and when the length of the buffer area section and the length of the idle parking spaces which are nearest to the buffer area section are larger than the length of the public transportation vehicles, the special traffic signal indicator lamp can be controlled to display the permission signal, so that the public traffic vehicles can drive through the intersection and enter the buffer zone road section, even if all parking spaces in the shared platform are occupied, the driven public traffic vehicles can be queued and wait in the buffer zone road section, otherwise, the public traffic vehicles can be stopped at the intersection, and the traffic of the intersection is influenced.
It should be noted that, when the length of the buffer area road segment is longer, the length of the public transportation vehicle occupying the buffer area road segment is shorter, and the length of the public transportation vehicle closest to the intersection, that is, the length of the public transportation vehicle about to enter the intersection, is less than the remaining length of the buffer area road segment, the public transportation vehicle can also be driven into the buffer area road segment to wait in line.
In addition, if the public transport vehicle can overtake, the public transport vehicle does not need to be driven into only the buffer area section which is not occupied, and the public transport vehicle can be driven into the shared platform, or the buffer area section which is occupied, but an unoccupied parking space exists in the shared platform, and when the parking space allows the public transport vehicle which is about to pass through the intersection to be driven into, the special traffic signal indicating lamp is made to display the permission signal, and the public transport vehicle is controlled to be driven into the parking space.
The method comprises the steps that the public transport vehicles are respectively provided with the corresponding serial numbers, so that the types and the lengths of the public transport vehicles can be known accurately through the serial numbers, the priorities of the types of the public transport vehicles can be set, when the public transport vehicles with higher priorities and the public transport vehicles with lower priorities are determined to wait before the intersection according to the serial numbers of the public transport vehicles, the public transport vehicles with higher priorities can be controlled to enter the buffer area road section, and the public transport vehicles with lower priorities wait for entering the control signal of the buffer area road section. The priority of the type of the public transportation vehicle can be set according to the number of the passengers of the public transportation vehicle, and the priority is not limited in the application.
It should be noted that, when the passing prohibition signal is a red light, the passing permission signal is a green light; the no-pass signal and the allow signal can also be a signal indication type specially set for public transport vehicles, for example, the no-pass signal and the allow signal are different letter signals or digital signals, which is not limited in the present application.
In addition, a private car or other vehicle travels according to the indication of a conventional traffic signal indicator lamp.
In conclusion, the special traffic signal indicator lamp is controlled, so that the condition that public transport vehicles enter the buffer area road section when the buffer area road section is occupied can be guaranteed, and the influence on the passing of other vehicles at the road junction caused by queuing of a plurality of public transport vehicles in the buffer area road section is avoided.
On the basis of the above-described embodiment:
as a preferred embodiment, the method further comprises the following steps:
judging whether the public transport vehicles positioned in the shared platform and nearest to the exit have finished the passenger getting-on and getting-off operation;
if yes, controlling a special traffic signal indicator lamp positioned at the intersection which is driven out of the direction of the shared platform to display a permission signal.
In order to make each public transport vehicle in the shared platform timely exit the shared platform after finishing the work of getting on and off passengers, so as to make a parking space for the public transport vehicles queued behind and make a way for the public transport vehicles behind, in the embodiment, when the public transport vehicle positioned in the shared platform nearest to the exit has finished the work of getting on and off passengers, that is, when the public transport vehicle at the forefront finishes the work of getting on and off classes, the special traffic signal indicating lamp positioned at the intersection in the direction of exiting the shared platform displays the permission signal, so that the public transport vehicle can timely exit the intersection, and the public transport vehicles queued up can conveniently enter the parking space to carry out the work of getting on and off passengers while the public transport vehicles at the back travel forwards.
It should be noted that, if the special traffic signal indicator lamp at the intersection located in the direction of exiting the shared platform displays the no-passing signal, but the public transport vehicle located in the shared platform and closest to the exit has completed the boarding and disembarking operation, the special traffic signal indicator lamp at the intersection located in the direction of exiting the shared platform can be preferentially set to display the no-passing signal, so as to ensure that the public transport vehicle can exit the shared platform in time.
As a preferred embodiment, after determining the occupancy of each parking space in the shared platform, the method further includes:

and controlling the special traffic signal indicator lamp to display the allowing signal, wherein the time for displaying the allowing signal is the preset time.
In this embodiment, the length of the public transportation vehicle can be determined by determining the number of the public transportation vehicle that is coming out of the common platform, and then the preset time for the special traffic signal indicator lamp to display the permission signal is determined according to the number of the public transportation vehicle that is going to pass through the intersection, the number of the public transportation vehicle that is coming out of the common platform, and the occupation situation of each parking space in the common platform, so that the public transportation vehicle that is going to pass through the intersection can enter the common platform.
It should be noted that, when it is determined that only one public transport vehicle can be currently allowed to enter the buffer area section according to the number of the public transport vehicle about to pass through the intersection, the number of the public transport vehicle exiting from the shared platform and the occupation condition of each parking space in the shared platform, only one public transport vehicle can be ensured to enter the buffer area section by setting the preset time, even if there is one public transport vehicle behind the public transport vehicle, when the public transport vehicle nearest to the intersection passes through the intersection, the special traffic signal indicating lamp can immediately display the passing prohibition signal so as to prohibit other vehicles from passing through the intersection.
As a preferred embodiment, before determining whether the buffer road segment is occupied by the public transportation vehicle, the method further includes:
determining the speed and position of each public transport vehicle;
the time and frequency of the passing prohibition signal and the passing permission signal are displayed by the special traffic signal indicating lamps of each intersection driving into the direction of the shared platform based on the speed and the position of each public traffic vehicle so as to control the number of the public traffic vehicles driving into the shared platform.
Each public transport vehicle in the embodiment is respectively provided with a positioning module and a speed measuring device, and the position and the speed of the public transport vehicle where the public transport vehicle is located can be sent to the processor, so that the processor can adjust the time and the frequency of the special traffic signal indicator lamps of each intersection for displaying the passing forbidding signals and the passing allowing signals according to the position and the speed of each public transport vehicle, the number of the public transport vehicles driving through each intersection can be controlled, the traffic of each intersection is coordinated and controlled, the phenomenon that too many vehicles drive into the buffer area road section to cause the occupation of the buffer area road section and the influence on the traffic of the intersection is avoided.
It should be noted that, although the time and frequency of the special traffic signal indicator lamp displaying the no-pass signal and the pass-through signal are set in the embodiment, when it is determined that there is a public traffic vehicle to drive into the common station according to the speed and the position of each public traffic vehicle, if the buffer section is not occupied and the special traffic signal indicator lamp displays the no-pass signal, the special traffic signal indicator lamp can be preferentially displayed with the pass-through signal so that the public traffic vehicle can drive into the common station.
