Description

Technical Field

[0001] The present invention relates to the field of computer technology, and more particularly to a method and device for evaluating streamline design of transfer space in a comprehensive transportation hub, and also to an electronic device and a processor-readable storage medium. Background Art

[0002] In recent years, with the rapid development of various modes of transportation, passenger travel needs have gradually shifted towards "high quality", "experiential" and "scenario-based". However, in the planning and construction of hubs, there are still streamline problems such as poor connection, low transfer efficiency and pedestrian chaos, which restrict the high-quality development of comprehensive transportation hubs and also affect the travel efficiency and quality of passengers. With the increase in the number of routes in urban comprehensive transportation hubs, the scale of hubs is also expanding, and long-distance and large-volume transfer spaces are inevitable. However, large-scale hubs with multiple transfers generally have large facilities. Due to the constraints of current conditions, they often use channel transfers to connect various stations, so the transfer distance is generally long. Long-distance transfer spaces are often accompanied by boring spatial experience and poor directional perception during the transfer process for passengers, which further leads to local streamline organization chaos. Therefore, it is an urgent problem to be solved in the refined design of hubs to fully consider the passenger walking experience, conduct a scientific and comprehensive evaluation of the level of hub streamline organization and use it to guide streamline design.

[0003] However, the existing technology usually focuses on the study of the streamline itself, and tends to ignore the characteristics of passenger traffic behavior and the importance of transfer facilities, and tends to ignore the function, scale and relationship of the building with the transfer streamline, focusing on efficiency factors. Therefore, there are certain limitations, and there is a lack of an effective evaluation method that considers the passenger walking experience; for example, it is easy to cause passenger congestion, streamline interweaving and other phenomena, which not only affects the passenger transfer experience, but also is not conducive to achieving the design goals of "fine" and "humanization" of the hub. In the existing technology, the evaluation method for passenger experience and satisfaction is mainly based on the AHP (hierarchical analysis) method, which often takes the passenger's own perception effect as the basis for evaluation, which will be very different due to personal likes and dislikes, and this method cannot be used in the planning stage, and cannot meet the requirements of objective evaluation. The selection of evaluation indicators related to the design of hub transfer streamlines often focuses on one aspect or one factor, without taking into account the requirements of systematicity and comprehensiveness, resulting in the evaluation index system cannot effectively and comprehensively reflect the nature of the evaluation problem itself, lacks consideration of factors related to passenger experience, and cannot effectively and comprehensively evaluate the streamline design level between various rail transit lines in the comprehensive transportation hub, resulting in the low accuracy of the existing evaluation method. Therefore, how to design an accurate and effective integrated transportation hub transfer space streamline design evaluation program has become a technical problem that needs to be solved urgently.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Based on the streamline design evaluation method for the transfer space of the integrated transportation hub of the present invention, the following describes in detail an embodiment thereof. Figure 1 As shown, it is a flow chart of the integrated transportation hub transfer space streamline design evaluation method provided by an embodiment of the present invention, and the specific implementation process includes the following steps:

[0042] Step 101: obtaining transfer experience index parameters corresponding to the transfer space streamline design object of the comprehensive transportation hub to be evaluated; wherein the transfer experience index parameters include average transfer distance index parameters, average transfer time index parameters, average passenger flow density index parameters of the transfer path, average index parameters of path smoothness, and average index parameters of walking comfort.

[0043] Specifically, the average transfer distance index parameter refers to the horizontal distance between all rail transit lines during transfer; for example, the average transfer distance index parameter d ij= The horizontal distance between all transfer modes (or all rail transit lines) i and j (subway, intercity, suburban, trunk railway, etc.), including the horizontal projection distance through stairs, escalators, and moving walkways. The starting and ending points are calculated from the entrance and exit gates. According to the proportion of each transfer volume, the weighted average is obtained to obtain the average transfer distance (m). This indicator is a negative indicator. The average transfer time indicator parameter is the average value of the corresponding transfer time between all rail transit lines during transfer; for example, the average transfer time indicator parameter v ij = the average transfer time (min) of all transfer modes (all rail transit lines) i and j (subway, intercity, suburban, trunk railway, etc.). This indicator is a negative indicator. The transfer path average passenger flow density indicator parameter is the ratio of the peak hourly passenger flow during transfer to the one-way length of the rail transit line, where the peak hourly passenger flow is the hourly passenger flow during the transfer peak between all rail transit lines; for example, the transfer path average passenger flow density indicator parameter q ij = peak hour passenger flow / one-way length of transfer path (or rail transit line) (p / h / m), which is a negative indicator, where the peak hour passenger flow is the peak hour passenger flow (p / h) between all rail transit lines i and j. The average index parameter of path smoothness is the average number of horizontal projection turning times of all rail transit lines during transfer; for example, the average index parameter of path smoothness r ij = The average number of horizontal projection turning times of all transfer channels (all rail transit lines) in the transfer flow line, starting from the gate (times), this indicator is a negative indicator. The walking comfort average index parameter is the average number of escalator usage times in all rail transit lines during transfer; for example, the walking comfort average index parameter c ij =The average number of escalator usages (excluding moving walkways) in the routes of all transfer lines (all rail transit lines) (times). This indicator is a negative indicator.

[0044] In the actual implementation of the present invention, based on the principles of scientificity, comprehensiveness, hierarchy, pertinence, operability, and combination of qualitative and quantitative, the transfer distance index parameter d is extracted. ij , transfer time index parameter v ij , the average passenger flow density index parameter q of the transfer path ij , path smoothness average index parameter r ij , walking comfort average index parameter c ij , a total of 5 transfer experience index parameters are used to evaluate the passenger transfer experience demand. Among them, i and j represent two different rail transit lines respectively.

[0045] It should be noted that before obtaining the transfer experience index parameters corresponding to the integrated transportation hub transfer space streamline design object to be evaluated, an embodiment of the present invention also includes pre-determining the integrated transportation hub transfer space streamline design object to be evaluated; the integrated transportation hub transfer space streamline design object corresponds to at least two transfer rail transit lines.

[0046] Step 102: Determine the index weight coefficient corresponding to the transfer experience index parameter.

[0047] In an embodiment of the present invention, it is first necessary to determine the information entropy value of the transfer experience index parameter, then determine the information utility value of the transfer experience index parameter based on the information entropy value, and finally determine the information entropy weight of the transfer experience index parameter based on the information entropy value and the information utility value of the transfer experience index parameter, and use the information entropy weight as the index weight coefficient corresponding to the transfer experience index parameter.

[0048] In the specific implementation process, the index weight coefficients α, β, γ, δ, and ε can be obtained through the entropy method. The transfer experience index parameters of each transfer experience index parameter are calculated using information entropy. In fact, the information utility value of the transfer experience index parameter is used for calculation. The larger the information utility value, the greater the importance of the corresponding transfer experience index parameter, that is, the higher the weight (the larger the index weight coefficient). A data system with n samples and m evaluation indicators (i.e., transfer experience index parameters) is formed based on pre-selection. The specific steps are as follows:

[0049] Specifically, the method of determining the information entropy value of the transfer experience index parameter includes the following steps (1)-(4):

[0050] (1) Construct a matrix Y with n samples and m evaluation indicators, which is expressed as:

[0051]

[0052] Wherein: (k=1, 2, 3, ..., n; f=1, 2, 3, ..., m).

[0053] (2) Matrix Y is normalized to obtain matrix B, which is expressed as:

[0054]

[0055] Wherein: (k=1, 2, 3, ..., n; f=1, 2, 3, ..., m).

[0056] (3) Evaluation indicators are usually divided into two categories: the larger the better and the smaller the better. The calculation formulas for each evaluation indicator relative to the optimal membership are:

[0057] The larger the better. Type indicator: bkf =(y kf -y min ) / (y max -y min );

[0058] The smaller the better. Index: b kf =(y max -y kf ) / (y max -y min );

[0059] Where:y kf is the element in the judgment matrix Y; b kf is an element in matrix B; y max ,y min They are respectively the most satisfactory value and the most unsatisfactory value in different samples under the same indicator.

[0060] It should be noted that the transfer experience index parameters used in the specific implementation of the present invention include but are not limited to the average transfer distance index parameter, the average transfer time index parameter, the average passenger flow density index parameter of the transfer path, the average index parameter of path smoothness, and the average index parameter of walking comfort. The types of the average transfer distance index parameter, the average transfer time index parameter, the average passenger flow density index parameter of the transfer path, the average index parameter of path smoothness, and the average index parameter of walking comfort are the smaller the better type of index.

[0061] (4) Calculate the information entropy value of the evaluation index. For m evaluation indexes and n samples, the entropy of the fth evaluation index is defined as:

[0062]

[0063]

[0064] Where: H f is the information entropy of the evaluation index f; b kf is the element in matrix B. To make Inf kf It makes sense, assuming that when f kf = 0, f kf Inf kf =0; k = 1, 2, 3, ..., n; f = 1, 2, 3, ..., m. It should be noted that the normal f kf The In function is meaningful only when it should be > 0, but in actual data, when f kf = 0, the value of In function approaches 0 infinitely, so for convenience we can assume that f kf =0, which can be understood as an optimization to adapt the entropy method to actual data calculation.

[0065] Specifically, determining the information utility value of the transfer experience index parameter based on the information entropy value includes the following step (5):

[0066] (5) Calculate the information utility value of the evaluation index.

[0067] E f =1-H f ;

[0068] Where: E f The information entropy H of the f-th evaluation index f The difference between 1 and 1 is the information utility value of the evaluation index.

[0069] Specifically, the step of determining the information entropy weight of the transfer experience index parameter based on the information entropy value and the information utility value of the transfer experience index parameter comprises the following step (6):

[0070] (6) Calculate the entropy weight of the evaluation index:

[0071]

[0072] Where: W f is the entropy weight of index f, that is, the index weight coefficient; 1-H f is the information utility value of the evaluation index f, H f is the information entropy of the evaluation index f; k and f represent one of the matrices composed of n samples and m evaluation indicators respectively.

[0073] Among them, the smaller the information entropy value, the greater the amount of information provided by the evaluation index, the greater the role it plays in the evaluation, the higher the information utility value of the evaluation index, and the higher the corresponding index weight coefficient.

[0074] For example, in the actual implementation of the present invention, based on the data system case sample library with n samples and m evaluation indicators, 6 typical large-scale comprehensive passenger transport hubs can be selected as the transfer space streamline design objects of the comprehensive transportation hub to be evaluated, and the transfer experience index parameter calculation method can be used to calculate the transfer experience index parameter. ij 、v ij ,q ij 、r ij 、c ij 5 transfer experience index parameters, and calculate the average value: average transfer distance index parameter Average transfer time indicator parameters Average passenger flow density index parameters of transfer paths Average index parameter of path smoothness Average index parameters of walking comfort That is: is the distance between all rail transit lines in the hub ijThe average value, is the distance between all rail transit lines in the hub ij The average value, is the distance between all rail transit lines in the hub ij The average value of r is the distance between all rail transit lines in the hub. ij The average value, c is the distance between all rail transit lines in the hub ij The data system consisting of 6 samples and 5 evaluation indicators is as shown in Table 1:

[0075] Table 1 Sample data

[0076]

[0077] The indicator weight coefficients are calculated: α, β, γ, δ, ε.

[0078] According to steps (1)-(6), the information entropy value H, information utility value E and index weight coefficient W of the evaluation index items are calculated respectively. Among them, the index weight coefficients α, β, γ, δ, and ε are 0.2322, 0.1326, 0.2541, 0.2447, and 0.1364 respectively; see Table 2 for details.

[0080]

[0081]

[0082] Step 103: Based on the transfer experience index parameters and the corresponding index weight coefficients, determine the passenger transfer experience demand between different rail transit lines; based on the passenger transfer experience demand, determine the level evaluation result of the integrated transportation hub transfer space streamline design object.

[0083] In an embodiment of the present invention, determining the indicator weight coefficient corresponding to the transfer experience indicator parameter in step 102 specifically includes: determining a first indicator weight coefficient corresponding to the average transfer distance indicator parameter; determining a second indicator weight coefficient corresponding to the average transfer time indicator parameter; determining a third indicator weight coefficient corresponding to the average passenger flow density indicator parameter of the transfer path; determining a fourth indicator weight coefficient corresponding to the average path smoothness indicator parameter; and determining a fifth indicator weight coefficient corresponding to the average walking comfort indicator parameter.

[0084] Furthermore, in this step, based on the transfer experience index parameter and the corresponding index weight coefficient, the passenger transfer experience demand between different rail transit lines can be determined, specifically including: based on the average transfer distance index parameter and its corresponding first index weight coefficient, the average transfer time index parameter and its corresponding second index weight coefficient, the transfer path average passenger flow density index parameter and its corresponding third index weight coefficient, the path smoothness average index parameter and its corresponding fourth index weight coefficient, the walking comfort average index parameter and its corresponding fifth index weight coefficient, the passenger transfer experience demand between different rail transit lines is determined.

[0085] For example: Demand for passenger transfer experience between rail transit lines I ij calculate:

[0086]

[0087] in, For each mode of transportation in the hub ij The average value, For each mode of transportation in the hub ij The average value, For each mode of transportation in the hub ij The average value, For the transportation mode in the hub ij The average value, For the transportation mode in the hub ij The average value of .

[0088] The determination of the level evaluation result of the streamline design object of the transfer space of the integrated transportation hub based on the passenger transfer experience demand is specifically as follows: based on the size of the passenger transfer experience demand, the level evaluation result corresponding to the streamline design object of the transfer space of the integrated transportation hub is determined; the size of the passenger transfer experience demand is positively correlated with the level evaluation result; for example: based on the above steps, the passenger transfer experience demand between different rail transit lines is obtained, wherein I ij The minimum value indicates that the streamline design level is the highest. ij The maximum value indicates that the streamline design level needs further design optimization.

[0089] In a specific embodiment, the daily passenger flow of the transfer space streamline design object of the comprehensive transportation hub is about 225,000 people / day, including transfer activities between four types of rail transit lines: intercity, M6, M101, and M22. The transfer experience index parameters in step 101 are shown in Table 3:

[0090] Table 3 Case data

[0091]

[0092] According to steps 102 and 103, the passenger transfer experience demand is calculated, and the result is shown in Table 4:

[0093] Table 4 Case transfer experience demand results

[0094]

[0095] The calculation results of the transfer experience demand of the transfer space streamline design object of the comprehensive transportation hub show that I 城际-M6 Highest, I M6-M22 Secondly, I 城际-M101 The lowest. Therefore, it can be seen that the streamline design level of Intercity-M101 is the highest, while the streamline design between the rail transit lines of Intercity-M6 and M6-M22 is insufficient, and needs to be optimized from the perspective of scheme design or operation management, so as to improve the passenger transfer walking experience and the overall design level of the hub. Through the actual verification of this case, it is shown that the passenger transfer experience demand degree formed by the present invention based on the five indicators of transfer experience can effectively and comprehensively evaluate the streamline design level between various transportation modes in the hub, which is better than the selection, and is applied to the evaluation and optimization of the scheme, which helps to improve the humanization and refinement of the streamline design.
