Abstract
Description
Technical Field
[0001] The present invention relates to the field of traffic planning route optimization, and specifically relates to a method, system and storage medium for optimizing the traffic route space and passenger flow direction map. Background Art
[0002] Traffic routes are the basic components of the transportation system, which are of great significance for people's travel, goods transportation and economic development. Traffic routes include stations and routes, such as traffic routes like roads, railways, air routes, etc. Traffic routes have a certain running direction, and passengers get on and off the routes at stations. The traffic route space and passenger flow direction map (referred to as "passenger flow direction map" for short) is a graphical tool used to display the passenger flow direction and quantity between stations on a certain traffic route, which can clearly show the travel patterns, passenger flow distribution and directionality of passengers, and provide important references for traffic planning and operation.
[0003] Currently, the way of traffic assessment is to obtain the cross-sectional passenger flow of each section through card swiping and ticket purchase information, and conduct statistical analysis on the traffic volume of the traffic route based on the cross-sectional passenger flow to guide the subsequent traffic planning; however, the way of directly analyzing the cross-sectional passenger flow has poor accuracy for the route space direction and passenger flow, rough direction description, and the existing cross-sectional passenger flow method can only count the passenger flow between two stations, with poor pertinence for the passenger flow of the route, and it is impossible to directly obtain the passenger flow situation of the entire route. Summary of the Invention

[0039] The following is a further detailed description through specific embodiments:
[0040] The embodiment is basically as shown in the appendix Figure 1 as follows:
[0041] Optimization method for traffic line space and passenger flow direction map, including:
[0042] S1. Obtain the station positions and cross-section passenger flow information of traffic lines in the target area, and generate a spatial direction division method; as shown in the following legend is a schematic diagram of rail transit lines and stations, obtain the cross-section passenger flow information of each station section through the card-swipe data of passengers entering and leaving the station during a certain period; the spatial direction division method includes: dividing the spatial direction into fixed intervals, and the directions within this interval are the same direction. According to the direction characteristics of the line, set the division threshold for the same direction, and those less than the threshold are in the same direction. For example, according to the set threshold, if |α Figure 2 -α 1 -α 2 |<θ, then the two directions are grouped into one group, where α 1 and α 2 are the direction values of two sub-lines, θ is the set division threshold, group all sub-lines in the spatial direction map and the passenger flow direction map to obtain the final grouping result. The range of the sub-line direction value is [0, 2π). According to needs, divide this range into n intervals, and the value range of the direction of the i-th division interval is [θ i , θ i+1 ), where θ i+1 >θ i . If the direction value α satisfies θ i ≤α<θ i+1 , then this sub-line belongs to the i-th direction, group all sub-lines in the spatial direction map and the passenger flow direction map to obtain the final grouping result. As shown in Figure 3 , in this embodiment, the space is divided into 8 directions, and the included angle between each direction is 45 degrees.
[0043] S2. Reconstruct the traffic lines based on the cross-section passenger flow information to obtain a reconstructed line map; that is, re-combine the stations according to the direction, as shown in the appendix Figure 4 . Through line reconstruction, the spatial division of the overall line is realized. The S2 includes: S21. Obtain the length corresponding to the unit passenger flow based on the total length and total cross-section passenger flow of the traffic line; S22. Obtain the direction of adjacent stations and the cross-section passenger flow of this adjacent station, obtain the passenger flow length between the two stations to get the passenger flow interval line; repeat to obtain the passenger flow interval lines of all adjacent stations; S23. Connect in the order of stations to obtain a reconstructed line map based on the passenger flow. The reconstructed line and the spatial division direction in this embodiment are as shown in Figure 5 . At the same time, the passenger flow data of each sub-line can be obtained, and using the passenger flow volume as the length of each sub-line, a direction map of the passenger flow direction and the spatial division can be obtained.
[0044] S3. Form sub - routes by combining adjacent stations in the reconstructed route map, and translate the starting points of the sub - routes to the same position to obtain the spatial direction map and the passenger flow direction map. Specifically, obtain the first and second stations of the route, connect the two stations to form a sub - route, and translate the starting point of the sub - route to a point. Process the remaining stations and sub - routes in the same way until the starting points of all sub - routes are translated to the same point, thus obtaining the spatial direction map and the passenger flow direction map. The spatial direction map is as shown in Figure 6 as shown, and the passenger flow direction map is as shown in Figure 7 as shown. The starting point of adjacent stations is determined according to the running direction. For example, for rail transit from place A to place B, the starting point is place A and the end point is place B; for the direction from place B to place A, the starting point is place B and the end point is place A.
[0045] S4. According to the spatial direction division method, group the spatial direction map and the passenger flow direction map respectively. In this embodiment, the fixed - direction division method is adopted for the spatial direction division method, and the entire space is divided into 8 directions, as shown in the appendix Figure 3 as shown.
[0046] S5. Based on the preset method, calculate the spatial direction value and the passenger flow direction value for the grouped spatial direction map and the passenger flow direction map. In this embodiment, by summing in the same direction, the magnitudes of the spatial direction and the passenger flow direction in this direction are obtained.
[0047] Since there is a certain correlation between urban rail transit and time, in this embodiment, the passenger flow direction maps of rail transit are extracted separately according to weekdays, weekends, and holidays to analyze the spatio - temporal distribution characteristics of rail transit passenger flow.
[0048] For large cities, the rail transit generally consists of a rail transit network composed of multiple rail lines. Using this method to analyze the spatio - temporal distribution characteristics of different rail lines provides a reference for the subsequent planning of rail transit lines, optimizes the composition of the rail transit network, and improves the operation efficiency.
[0049] It also includes a traffic line space and passenger flow direction map optimization system, which uses the above - mentioned traffic line space and passenger flow direction map optimization method.
[0050] It also includes a storage medium storing a computer program, and when the computer program runs, it executes the above - mentioned traffic line space and passenger flow direction map optimization method.
[0051] The above are only embodiments of the present invention, and common general technical solutions and / or characteristics in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solutions of the present invention, several variations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
