The development of urban rail transit will eventually form a rail transit network. In the current situation, trains with a single line are often driven on each rail traffic line, namely, a form of independent operation of branch lines. The operation management corresponding to single-line operation is relatively simple, but the special wireless system of each line operates independently, and vehicles of each line are special, so that cross-line operation cannot be performed, and adverse factors such as high operation cost, single operation situation, resource waste and the like are brought to a rail transit operation unit in vehicle allocation, resource sharing and operation modes. In order to solve the problem of urban rail transit at present, the interconnection idea based on networked operation design is developed by combining the development experience of the urban rail transit abroad.
Interconnection and intercommunication are favorable for realizing reasonable distribution of resources, the service level is improved systematically, the defects caused by single-wire independent operation are overcome, and the situation that lines and stations are transformed after operation is avoided. The urban rail transit transportation organization scheme based on interconnection is more flexible, the requirement for coordination between lines is higher, and meanwhile, the method has an obvious effect of improving the passenger service level. Based on the background, vehicle sharing configuration can be carried out on adjacent lines, and reasonable allocation of resources is facilitated. The train can be borrowed and transferred to the adjacent line to operate when the operation is in the peak period, and the train can be borrowed and transferred to other lines when the operation is in the peak period, so that the number of vehicles allocated to each line is reduced to a certain extent, and resources are saved. But at present, no better configuration method exists for adjacent lines under interconnection and intercommunication in the vehicle configuration scale.
To this end, fig. 1 shows a schematic flowchart of a method for optimizing a vehicle configuration based on interconnection, according to an embodiment of the present invention, and referring to fig. 1, the method includes:
s11, obtaining the passenger flow of each traffic interval on an uplink section and a downlink section which take a line crossing point as a boundary point on a first line and a second line, wherein the first line and the second line can be interconnected and communicated, and the traffic interval is a traffic interval between adjacent stations;
s12, determining the number of vehicles arranged on the first line, the number of vehicles arranged on the second line and the number of vehicles arranged across lines according to the passenger flow of each vehicle interval.
For step S11, it should be noted that, in the embodiment of the present invention, two lines that are interconnected and intercommunicated usually have one cross-line point, and in the embodiment, the method is explained mainly by referring to the fact that two lines have one cross-line point.
Fig. 2 shows a schematic view of the passenger flow distribution of two lines. Referring to fig. 2, a No. 1 line (i.e., the first line mentioned in this embodiment) and a No. 2 line (i.e., the second line mentioned in this embodiment) have a crossover point O. Each line is generally divided into an uplink line or a downlink line in the running process of the train. For example, in line 1, a is the originating station, B is the terminating station, and from a to B is the uplink, and from B to a is the downlink. For example, in line 2, C is the originating station, D is the terminating station, and from C to D is the uplink, and from D to C is the downlink.
For this reason, if the crossover point is taken as the boundary point, the uplink of line No. 1 is divided into two uplink segments by point O, that is: AO and OB; the downlink is divided into two downlink segments by O, namely: BO and OA. Similarly, the uplink of line 2 is divided into two uplink segments by point O, that is: CO and OD; the downlink is divided into two downlink segments, DO and OC, at point O.
In the embodiment of the invention, each line is divided into a plurality of traffic intervals, and the traffic intervals are traffic sections between adjacent stations. For this reason, a plurality of traveling sections can exist in the upstream section and the downstream section.
In the embodiment of the invention, the passenger flow volume of each traffic interval is estimated in advance through a passenger flow prediction model. The passenger flow prediction model has a lot of information according to the passenger flow entering the station, the position of the train, the current time, the speed, the running interval time and the like, and is not repeated herein. The passenger flow prediction model corresponding to the large-scale activity scene is a large-scale activity passenger flow algorithm. And aiming at the passenger flow prediction model corresponding to the sudden passenger flow situation, the passenger flow prediction model is a sudden passenger flow algorithm. These two passenger flow algorithms belong to the prior art and are not described in detail herein.
In the embodiment of the invention, because the vehicle carries passengers for transportation, the estimation of the vehicle configuration scale can be realized by analyzing the passenger flow. Therefore, after the passenger flow volume of each vehicle section in the uplink section and the downlink section which take the cross-line point as the boundary point on the first line and the second line is obtained, the passenger flow volume needs to be analyzed and processed, so that the vehicle configuration number on the first line, the vehicle configuration number on the second line and the cross-line vehicle configuration number are determined.
According to the vehicle configuration optimization method based on interconnection and intercommunication provided by the embodiment of the invention, the number of the vehicle configurations on the first line, the number of the vehicle configurations on the second line and the number of the vehicle configurations on the crossline are obtained by analyzing and processing the passenger flow volume of each vehicle interval on the uplink section and the downlink section which take the crossline point as the demarcation point on the first line and the second line, so that the vehicle configuration scale required in the operation process of adjacent lines on interconnection and intercommunication is realized, the mutual coordination of train operation between the lines is realized, the number of the vehicle configurations required by the independent operation of the adjacent lines is reduced, and the operation cost is reduced.
Fig. 3 is a flowchart illustrating a method for optimizing vehicle configuration based on interconnection, according to an embodiment of the present invention, and referring to fig. 3, the method includes:
s21, obtaining the passenger flow of each traffic interval on an uplink section and a downlink section which take a line crossing point as a boundary point on a first line and a second line, wherein the first line and the second line can be interconnected and communicated, and the traffic interval is a traffic interval between adjacent stations;
s22, determining reference interval passenger flow corresponding to an uplink section and a downlink section on the first line and the second line according to the passenger flow of each traffic interval, wherein the reference interval passenger flow is the maximum passenger flow in the passenger flow of each traffic interval on the uplink section and the downlink section;
s23, determining a first section passenger flow volume and a second section passenger flow volume corresponding to the first line according to the reference section passenger flow volume, and determining a third section passenger flow volume and a fourth section passenger flow volume corresponding to the second line; the first section passenger flow volume and the second section passenger flow volume are respectively the passenger flow volume with the numerical value arranged in the first two positions in the reference section passenger flow volume corresponding to the first line, and the third section passenger flow volume and the fourth section passenger flow volume are respectively the passenger flow volume with the numerical value arranged in the first two positions in the reference section passenger flow volume corresponding to the second line;
s24, determining the number of the vehicles arranged on the cross-line according to the first section passenger flow volume, the second section passenger flow volume, the third section passenger flow volume and the fourth section passenger flow volume, determining the number of the vehicles arranged on the first line according to the second section passenger flow volume, and determining the number of the vehicles arranged on the second line according to the fourth section passenger flow volume.

Therefore, the maximum passenger flow volume is selected from the passenger flow volumes of the respective traffic zones as the reference zone passenger flow volume of the respective ascending zone or the descending zone. The passenger flow volume of the reference interval is used as an analysis basis for subsequently determining the vehicle configuration number.
For example, the reference section passenger flow volumes corresponding to the two upstream sections and the two downstream sections of the line No. 1 shown in fig. 2 are qAO、qOB、qBOAnd q isOA. The passenger flow of the reference interval corresponding to two uplink sections and two downlink sections of the No. 2 line is qCO、qOD、qDOAnd q isOC。
After the passenger flow volumes of the reference sections corresponding to the first line and the second line are determined, the passenger flow volumes with the first two numerical values are selected from the passenger flow volumes of the reference sections corresponding to the first line and are respectively used as the passenger flow volumes of the first section and the second section. And selecting the passenger flow with the numerical value arranged in the first two from the reference section passenger flow corresponding to the second line as the third section passenger flow and the fourth section passenger flow respectively.
E.g. reference interval passenger flow qAO、qOB、qBOAnd q isOAMiddle qAOAnd q isBOThe first two of the four passenger flows are ranked, for which q is assignedAOAs the first section passenger flow volume, q isBOAs the second zone passenger flow volume.
The passenger flow rate in the reference interval is qCO、qOD、qDOAnd q isOCMiddle qODAnd q isOCThe first two of the four passenger flows are ranked, for which q is assignedODAs the third section passenger flow volume, q isOCAs the fourth zone passenger flow volume.
After the first, second, third and fourth section passenger flows are obtained, the number of the vehicle configurations of the crossroad can be determined according to the first, second, third and fourth section passenger flows, the number of the vehicle configurations of the first and second roads can be determined according to the second section passenger flow, and the number of the vehicle configurations of the second road can be determined according to the fourth section passenger flow.

in the embodiment of the invention, the first cross-line departure frequency is determined by adopting a frequency formula according to the first interval passenger flow and the second interval passenger flow. And determining a second cross-line departure frequency by adopting a frequency formula according to the passenger flow volume of the third interval and the passenger flow volume of the fourth interval. And determining the reference cross-line departure frequency according to the first cross-line departure frequency and the second cross-line departure frequency.
