Description

Technical Field

[0001] The present application belongs to the technical field of rail transit prediction, and in particular to a method, device and equipment for predicting passenger volume of urban rail transit. Background Art

[0002] Weather changes have a close impact on traffic volume. When the weather changes, people will adopt different modes of transportation to meet their transportation needs. For example, on rainy and snowy days, some people who originally traveled by bicycle or electric vehicle will choose to drive or take urban public transportation. Because cars are exposed to the natural environment on the road, they are subject to the influence of the natural environment. In rainy and snowy weather, the roads will become more congested than usual. During the rush hour on weekdays, if the city has rail transit, people will choose rail transit. This is because most rail transit is built underground, and rainy and snowy weather has little impact on rail transit travel. However, rainy and snowy weather will lead to an increase in rail transit travel, which often puts pressure on rail transit operations.

[0003] In the current research on the impact of weather on urban rail transit travel, the focus is mainly on statistical analysis based on historical weather conditions and urban rail transit passenger volume, and with the development of big data technology, continuous data mining and the introduction of new models to predict future urban rail transit passenger volume, but the current passenger volume prediction methods have obvious problems. For example: when predicting rail transit passenger volume, regional factors are not considered; when analyzing weather historical data to predict passenger volume, only a certain meteorological analysis is relied on. For example, on rainy days, the impact of rain itself on passenger volume prediction is considered, but the impact of meteorological level (how much rainfall) on passenger volume is not considered, which causes deviations in the prediction results, thereby affecting the reasonable scheduling and allocation of public resources by rail transit operating departments. Summary of the invention

[0004] The embodiments of the present application provide a method, device and apparatus for predicting the passenger volume of urban rail transit, so as to more accurately predict the passenger volume of urban rail transit.

[0005] This application is implemented through the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a method for predicting passenger volume of urban rail transit, comprising:

[0007] Obtain the target city's rail transit daily passenger volume, daily maximum temperature, daily minimum temperature, daily wind level, daily weather conditions, as well as the maximum temperature of a future date, the minimum temperature of a future date, the wind level of a future date, and the weather conditions of a future date.

[0008] The historical daily wind level is converted into numerical data to obtain the first data; the historical daily weather conditions are converted into numerical data to obtain the second data.

[0009] Based on the historical daily maximum temperature, the historical daily minimum temperature, the first data and the second data, the historical daily weather comfort index is obtained.

[0010] Based on the historical daily weather comfort index and the historical daily passenger volume of rail transit, the historical daily decoupling evaluation index is obtained.

[0011] Based on the historical daily decoupling evaluation index, the maximum temperature of the future date, the minimum temperature of the future date, the wind level of the future date and the weather conditions of the future date, the passenger volume of the target city's rail transit on the future date is predicted.

[0012] In a second aspect, an embodiment of the present application provides a device for predicting passenger volume of urban rail transit, comprising:

[0013] The data acquisition module is used to obtain the target city's rail transit historical daily passenger volume, historical daily maximum temperature, historical daily minimum temperature, historical daily wind level, historical daily weather conditions, as well as the maximum temperature of a future date, the minimum temperature of a future date, the wind level of a future date, and the weather conditions of a future date.

[0014] The data conversion module is used to convert the historical daily wind level into numerical data to obtain the first data; and convert the historical daily weather conditions into numerical data to obtain the second data.

[0015] The first operation module is used to obtain a historical daily weather comfort index based on the historical daily maximum temperature, the historical daily minimum temperature, the first data and the second data.

[0016] The second operation module is used to obtain a historical daily decoupling evaluation index based on the historical daily weather comfort index and the historical daily passenger volume of rail transit.

[0017] The result output module is used to predict the passenger volume of the target city rail transit on a future date based on the historical daily decoupling evaluation index, the maximum temperature on a future date, the minimum temperature on a future date, the wind level on a future date, and the weather conditions on a future date.

[0018] In a third aspect, an embodiment of the present application provides an electronic device, comprising: a processor and a memory, the memory being used to store a computer program, and when the processor executes the computer program, the method for predicting the passenger volume of urban rail transit as described in any one of the first aspects is implemented.

[0019] It can be understood that the beneficial effects of the second to third aspects mentioned above can be found in the relevant description of the first aspect mentioned above, and will not be repeated here.

[0020] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0021] The present application establishes a weather comfort index through the historical daily maximum temperature, the historical daily minimum temperature, the historical daily wind level and the historical daily weather conditions, and links the weather comfort index with the passenger volume to obtain a decoupling evaluation index. The application uses the local historical daily decoupling evaluation index, the maximum temperature, the minimum temperature, the wind level and the weather conditions of future dates to predict the passenger volume of future dates. It comprehensively considers factors such as temperature, wind level and weather conditions, avoids the traditional method of only considering weather conditions, and can more accurately predict the passenger volume. In addition, it abandons the traditional method of using time series models, artificial neural network models and machine learning models to predict passenger volume, and instead considers the decoupling relationship between the local historical daily weather comfort index and passenger volume. Using the decoupling relationship for prediction can better adapt to local conditions and obtain passenger volume prediction results with more local characteristics.

[0027] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0029] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0030] As used in the specification and appended claims of this application, the term "if" can be interpreted as "when" or "uponce" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0031] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0032] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment.

The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0033] At present, regional factors are not taken into account when considering the prediction of rail transit travel volume; when analyzing historical weather data for prediction, only a certain meteorological analysis is relied upon. For example, when considering rainy days, the impact of rain itself on passenger volume is considered, but the impact of meteorological level on passenger volume is not considered. At that time, the predicted results will be biased, which will affect the rail transit operation department's reasonable scheduling and allocation of public resources.

[0034] Based on the above problems, the embodiment of the present application provides a method for predicting urban rail transit passenger volume. In addition to considering the influence of temperature, wind level and weather conditions, it also takes into account the impact of the latitude of the target city (climate changes in different regions) on passenger volume, thereby improving the accuracy of passenger volume prediction and obtaining more accurate passenger volume prediction results, thereby providing a certain data basis for local rail transit departments, facilitating staff to make real-time adjustments to rail transit operations based on different predicted passenger volumes, thereby reducing waste of resources and saving resources.

[0035] Figure 1 is a schematic diagram of the process of predicting the passenger volume of urban rail transit provided by an embodiment of the present application, with reference to Figure 1 , the detailed description of the urban rail transit passenger volume prediction method is as follows:

[0036] Step 101, obtaining the target city's rail transit daily passenger volume, daily maximum temperature, daily minimum temperature, daily wind level, daily weather conditions, as well as the maximum temperature of a future date, the minimum temperature of a future date, the wind level of a future date, and the weather conditions of a future date.

[0037] Specifically, weather conditions refer to sunny days, light rain, showers, light snow, heavy snow, etc. Wind level means no wind, soft wind, light wind, breeze, etc.

[0038] Step 102, converting the historical daily wind level into numerical data to obtain first data; converting the historical daily weather conditions into numerical data to obtain second data.

[0039] Specifically, the wind level can be converted into numerical data through Table 1. The specific process includes: determining the corresponding wind speed range through the wind level, and randomly selecting a number in the wind speed range as the first data.

[0040] The historical daily wind level corresponds to a wind speed range, so there is a corresponding first data for each day in history.

[0041] Table 1

[0042]

[0043] Specifically, the weather conditions can be converted into numerical data through Table 2 and Table 3. The specific process includes: determining the corresponding precipitation level through the weather conditions; and randomly selecting a number in the precipitation range in the precipitation level as the second data.

[0044] The historical daily weather conditions all correspond to a precipitation range, so there is a corresponding second data for the historical daily weather conditions.

[0045] Table 2

[0046]

[0047]

[0048] Table 3

[0049]

[0050] Specifically, for example, when the wind level on A day in A month in A year is a breeze and the weather condition is a blizzard, the corresponding first data is any one between 3.4 and 5.4, and the corresponding second data is any one between 10.0 and 19.9.

[0051] Step 103, obtaining a historical daily weather comfort index based on the historical daily maximum temperature, the historical daily minimum temperature, the first data and the second data.

[0052] Exemplarily, step 103 may include:

[0053] Based on the historical daily maximum temperature, the historical daily minimum temperature and the first data, combined with the second formula, the historical daily clothing index is obtained.

[0054] The historical daily maximum temperature, historical daily minimum temperature, first data, second data and historical daily clothing index are standardized by the range standardization method.

[0055] The entropy method is used to calculate the proportion and weight of the standardized historical daily maximum temperature, the proportion and weight of the standardized historical daily minimum temperature, the proportion and weight of the standardized first data, the proportion and weight of the standardized second data, and the proportion and weight of the historical daily clothing index.

[0056] Based on the standardized proportion and weight of the historical daily maximum temperature, the standardized proportion and weight of the historical daily minimum temperature, the standardized proportion and weight of the first data, the standardized proportion and weight of the second data, and the standardized proportion and weight of the historical daily clothing index, combined with the third formula, the historical daily weather comfort index is obtained.

[0057] The second formula can be:

[0058]

[0059] Among them, P i5 represents the clothing index of the i-th day, T max Indicates the maximum value of the historical daily maximum temperature, T i ave represents the average temperature of the i-th day, which is equal to the average of the highest and lowest temperatures of the i-th day. H represents 75% of the human metabolic rate, R represents the solar constant, and α i represents the solar altitude angle on the i-th day, v i represents the first data of the i-th day;

[0060] Specifically, the calculation of the clothing index incorporates the latitude of the target city and comprehensively considers climate change in different regions, which can ensure the accuracy of the subsequent calculation of the weather comfort index, and then ensure the accuracy of the decoupling relationship between the weather comfort index and passenger volume, and finally ensure the accuracy of the predicted passenger volume.

[0061] Specifically, the value of H can be 87W / m 2 , the value of R can be 1357W / m 2 , assuming that the latitude of the research area is β, the solar altitude angle α in spring and autumn is 90°-β, the solar altitude angle α in summer is 90°-β+23°26′, and the solar altitude angle α in winter is 90°-β-23°26′.

[0062] The third formula can be:

[0063] C i =W1P i1 +W2P i2 +W3P i3 +W4P i4 +W5P i5

[0064] Among them, C i represents the weather comfort index of the i-th day, P i1 represents the weight of the highest temperature on the ith day after standardization, W1 represents the weight of the highest daily temperature after standardization, P i2 represents the weight of the lowest temperature on the ith day after standardization, W2 represents the weight of the lowest daily temperature after standardization, and P i3 represents the proportion of the first data of the i-th day after the standardization process, W3 represents the weight of the first data after the standardization process, and P i4 represents the proportion of the second data of the i-th day after the standardization process, W4 represents the weight of the second data after the standardization process, and P i5W5 represents the weight of the clothing index of the i-th day after standardization, and W6 represents the weight of the historical daily clothing index after standardization.

[0065] Specifically, the weather comfort index calculation formula of this solution also incorporates the clothing index, so that the calculated weather comfort index is more accurate and can more accurately reflect the decoupling state between weather comfort and passenger volume.

[0066] Specifically, standardizing the historical daily maximum temperature, the historical daily minimum temperature, the first data, and the second data by using the range standardization method may include:

[0067] The historical daily maximum temperature, historical daily minimum temperature, first data, second data and historical clothing index are all used as an indicator, and the historical date is used as the sample number to establish a matrix There are a total of m samples in the matrix X, and each sample contains 5 indicators.

[0068]

[0069] Among them, X i1 represents the maximum temperature on the i-th day after standardization, x m1 Represents the maximum temperature on the mth day.

[0070]

[0071] Among them, X i2 represents the minimum temperature of the i-th day after standardization, x m2 Indicates the minimum temperature on the mth day.

[0072]

[0073] Among them, X i3 represents the first data of the i-th day after standardization, x m3 Indicates the first data of the mth day.

[0074]

[0076]

[0077] Among them, X i5 represents the clothing index of the i-th day after standardization, x m5 Represents the clothing index on the mth day.

[0078] Specifically, in order to make the weights and proportions of subsequent calculations more accurate in calculating the weather comfort index, it is necessary to eliminate the dimensional differences of the acquired data to avoid the influence of the value of the data itself on its proportion in the calculation process of the weather comfort index, resulting in inaccurate calculation of the final data and failure to achieve the purpose of accurately predicting passenger volume.

[0079] Exemplarily, calculating the proportion and weight of the standardized historical daily maximum temperature, the proportion and weight of the standardized historical daily minimum temperature, the proportion and weight of the standardized first data, the proportion and weight of the standardized second data, and the proportion and weight of the standardized historical daily clothing index respectively by the entropy method may include:

[0172] Assuming that the future date is a Monday among working days, then it is necessary to obtain the decoupling status of Mondays on each working day in history. Assuming that there are a total of 20 Mondays on working days, the number of occurrences of the decoupling states of expansion negative decoupling, expansion connection, weak decoupling, strong decoupling, recession decoupling, recession connection, weak negative decoupling and strong negative decoupling are 1, 1, 4, 1, 3, 1, 2 and 7 respectively.
