Description

Technical Field

[0001] The present invention belongs to the field of intelligent traffic big data, and in particular to a method and system for setting up expressway passenger transfer points and routes based on multi-source big data. Background Art

[0002] Since the 1990s, the rapid development of expressways has brought about the rapid development of inter-city road passenger transport based on expressways. Expressways are closed and can only be entered and exited from the expressway entrance and exit toll stations set up along the line. In addition, previous policy documents prohibit passengers from getting on and off outside the stations. In this way, cities along the expressways can only operate point-to-point road passenger routes from one city’s highway passenger station to another city’s highway passenger station. A separate road passenger route is required between every two cities, and multiple road passenger routes need to be opened between multiple cities. With the rapid construction and network operation of high-speed railways and the rapid popularization of private cars, especially affected by the epidemic, the passenger flow on road passenger routes has dropped sharply. The actual load rate of many routes is less than 30%, and the routes are difficult to continue to operate due to declined efficiency. Moreover, this mode of operating point-to-point road passenger routes between cities has also caused a lot of waste of resources.

[0003] In recent years, national policies have adjusted the relevant regulations on prohibiting passengers from getting on and off outside the station. The latest proposal is that stops can be set up outside the passenger station, and node transportation is encouraged. There are few related studies on highway passenger transfer stations at home and abroad, and some studies are relatively scattered. In terms of academic papers, "Service Model of "Highway Passenger Transfer Station"" introduces the background and necessity of setting up the Diaozhen Passenger Transfer Station on the Jiqing Expressway, the site selection and service form, safety and service management, etc. "Research on the Development of Road Passenger Node Transportation" analyzes the connotation, characteristics and significance of node transportation, and proposes a development model for node transportation. "Research on the Setting Conditions and Transfer Mode of Passenger Transfer Stations in Highway Service Areas" proposes five conditions that need to be met for the setting up of passenger transfer stations in service areas based on the investigation and analysis of seven typical practical cases in China, from the aspects of travel demand, geographical location, surrounding traffic, route resources, and service scope, and analyzes the characteristics and applicability of two typical transfer modes: the bus passenger station mode and the simple waiting point mode. "Layout and Traffic Organization Design of Passenger Transfer Stations in Highway Service Areas" divides the layout of passenger transfer stations into two categories: independent settings and integration with the main functional area, based on the location of the passenger transfer stations relative to the main functional area of ​​the service area. It studies the characteristics and selection points of different layout plans, and proposes traffic organization principles and evaluation indicators for passenger transfer stations in service areas as the main basis for selecting layout plans. In terms of patents, "Highway Service Area Passenger Transfer Station Site Selection Evaluation Method Based on Set Pair Analysis" (CN113052384A) constructs evaluation indicators and uses set pair analysis to select the site of passenger transfer stations in service areas. "A Method for Evaluating the Energy Saving and Emission Reduction Effects of Passenger Transfer Stations in Highway Service Areas" (CN113011732A) constructs a fuel consumption and carbon emission model based on the analysis of the operation mode of passenger stations in service areas, and quantitatively evaluates the energy saving and emission reduction effects of passenger transfer stations in service areas. In general, the research on highway passenger transfer points mainly focuses on the setting conditions, service models, and case analysis. Only a small number of studies have discussed the location of passenger transfer points from a theoretical perspective, without considering the actual passenger flow demand for transfers, and there is a lack of engineering and technical methods that can be used for specific implementation. In the current situation where there is an urgent need to develop node transportation, it is urgent to set up appropriate transfer points based on the actual passenger flow demand along the highway.

[0088] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0089] Highway passenger transfer stations refer to transfer stations set up at highway service areas, toll stations and other places. They have the functions of boarding, transferring, changing, and connecting. Passengers can stop to pick up and drop off passengers. Passengers who get on the bus gather here to board the bus, and passengers who get off transfer and change here. In the prior art, the research on highway passenger transfer stations mainly focuses on the setting conditions, service models, and case analysis. Only a small number of studies have been conducted on the location of passenger transfer stations from a theoretical perspective, without considering the actual demand for connecting passenger flow, and there is a lack of engineering and technical methods that can be used for specific implementation. In the current situation where node transportation is urgently needed to be developed, it is urgent to set up appropriate transfer points according to the actual demand for connecting passenger flow along the highway. The inventor has found through long-term research that the rapid development of big data provides a powerful technical means to solve this problem. If we can use road passenger ticket data to analyze the distribution of starting and ending points of inter-city road passenger bus lines, use mobile phone signaling data to analyze inter-city people's travel activities, use ticket data, mobile phone signaling data and other multi-source big data fusion analysis to extract the travel chain of inter-city road passenger bus lines that can be used, and establish a road passenger connection point setting method and bus line arrangement method, then we can accurately grasp the use of road passenger bus lines based on multi-source big data. Based on the passenger flow demand for scheduled bus travel, passenger transfer points with passenger boarding, transfer, interchange and connection functions are set up in highway service areas, entrance and exit toll stations and other places according to actual passenger flow demand, forming an operation mode of "highway main line + city transfer branch line". The city transfer branch line is used to load the highway main line, optimize the transportation supply between regions, and realize the reasonable layout of transportation routes between cities. It can not only increase the actual load rate and economic benefits of scheduled bus lines, but also promote the intensive use of resources and improve the level of energy conservation and emission reduction in road passenger transport.

[0090] This embodiment proposes a method and system for setting up highway passenger transfer points and routes based on multi-source big data. It uses the fusion analysis of multi-source big data such as ticket data and mobile phone signaling data to accurately grasp the travel chain of passenger flow that can be used for road passenger transport routes, and arranges highway passenger transfer points based on actual passenger flow demand to achieve the purpose of improving the operating efficiency of the routes.
