DETAILED DESCRIPTION

[0010] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0011] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0012] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0013] See also Figure 1 , the embodiment of the present application provides a method for processing highway travel data, comprising: Obtain toll data for the target section of the expressway, including toll data from toll booths and toll gantries; The toll collection data with complete entry and exit time is recorded as valid data. The entry and exit time is the time of entering the toll station and the time of leaving the toll station; At least one of the entrance and exit times of the toll data is missing. If the exit node and / or the entry node can be determined based on the toll data of the toll gantry, the toll data is recorded as valid data. The exit node and the entry node are the nodes for entering or exiting the target section outside the toll station in the target section. Valid data is retained, and other charging data outside the valid data is deleted as abnormal data.

[0014] The basis of the highway travel data in this application can be the toll data obtained from the toll collection system of the highway operation management department. The toll data generally includes the time when the vehicle enters and exits the highway, the name of the toll station, the vehicle model and other related information. The starting and ending points of the vehicle travel are important parameters based on the research of toll data. In order to eliminate the influence of noise data, the data needs to be cleaned to delete invalid data and retain only valid data. General data cleaning is to retain valid data by deleting incomplete data of the starting and ending points. However, there are many factors that lead to the lack of information on entering and exiting toll stations in the toll data. Using the lack of information on entering and exiting toll stations as the criterion for judging invalid data may mistakenly delete valid data, resulting in a large deviation in subsequent research. For example, the highway runs through multiple provinces and is interconnected with other highways. Therefore, when studying the data of the highway in a certain province, the vehicle may leave or enter the target highway section through the highway interchange, resulting in the lack of entry and / or departure information. If such toll data is deleted, the data of such travel will be missing.

[0015] In the method of the present application, valid data is determined by toll station information and gantry information in the target section of the expressway, valid data is extracted from the original data, and abnormal data is discarded to achieve the purpose of data cleaning. This avoids the problem of accidental deletion of valid data, and can fully retain the travel information of the vehicle and achieve data cleaning.

[0016] For toll data with complete entry and exit times, since it contains the information of entering the toll station and exiting the toll station, it can be judged as valid data and recorded, so as to extract valid data from the original data and discard invalid data. For toll data with at least one entry and exit time missing, for example, the information of entering the toll station is missing, or the information of exiting the toll station is missing, or the information of entering the toll station and exiting the toll station are both missing, the exit node and / or the entry node can be determined based on the toll data of the toll gantry. If the missing exit node and / or entry node can be determined, the toll data can be judged as valid data and recorded as valid data, so as to extract valid data from the original data and discard invalid data.

[0017] In the present application, the exit node and the entry node are nodes for entering or exiting the target road section outside the toll station in the target road section.

[0018] In some embodiments, the nodes for entering or exiting the target road section outside the toll station include the highway interconnection node and the provincial boundary node in the target road section. For example, a vehicle may enter or exit the target road section from the highway interconnection node, so that the toll station of the target road section fails to record the corresponding information. Alternatively, a vehicle may enter or exit the target road section from the provincial boundary node, so that the toll station of the target road section fails to record the corresponding information.

[0019] Take the highway connecting Beijing and Tianjin as an example. If a vehicle enters the Beijing section of the highway from Tianjin, the toll data of the Beijing section of the highway will lack the information of the vehicle entering the toll station. If the vehicle enters the Beijing section and then leaves the highway from the highway interchange node, the toll data of the Beijing section of the highway will also lack the information of the vehicle leaving the toll station.

[0020] Alternatively, if a vehicle leaves the Beijing section of the expressway and enters Tianjin, the toll data for the Beijing section of the expressway will lack the information about the vehicle exiting the toll station. If the vehicle enters the expressway from an expressway interchange node, the toll data for the Beijing section of the expressway will also lack the information about the vehicle entering the toll station.

[0021] There are also toll gantries on the highway. In order to facilitate non-stop billing, toll gantries are set up near nodes such as highway interchanges and provincial boundaries. For valid data, the vehicle's entry node or exit node can be determined based on the toll information of the toll gantries. Therefore, if the exit node and / or entry node can be determined based on the toll data of the toll gantries, then the toll data is valid data.

[0022] In some embodiments, at least one of the entrance and exit times of the toll data is missing. If the exit node and / or the entrance node can be determined based on the toll data of the toll gantry, the toll data is recorded as valid data, including: the toll data has the time of entering the toll station. When the time of exiting the toll station is missing, if the last gantry in the toll data is the gantry closest to the highway interchange node or provincial boundary node in front, then the highway interchange node or provincial boundary node closest to the last gantry is the exit node of the toll data, and the toll data is valid data. The toll data with missing entrance and exit times includes at least one gantry information, that is, the vehicle passes through at least one gantry in the target section and is recorded by the gantry. After the vehicle enters the target section from the toll station, if it exits the target section from the highway interchange node or provincial boundary node, the highway interchange node or provincial boundary node that the vehicle exits will be recorded by the gantry, and the last gantry in the toll data of the vehicle is the gantry closest to the highway interchange node or provincial boundary node that it exits.

[0023] In some embodiments, when the toll data has the time of entering the toll station but lacks the time of exiting the toll station, if there are other gantries between the last gantry in the toll data and the nearest highway interchange node or provincial boundary node in front, the toll data is abnormal data.

[0024] In this application, the front refers to the direction of the front of the vehicle, and the rear refers to the direction of the rear of the vehicle.

[0025] In some embodiments, at least one of the entrance and exit times of the toll data is missing. If the exit node and / or the entry node can be determined based on the toll data of the toll gantry, the toll data is recorded as valid data, including: when the toll data has the time of exiting the toll station and the time of entering the toll station is missing, if the first gantry in the toll data is the gantry closest to the highway interchange node or provincial boundary node behind, then the highway interchange node or provincial boundary node closest to the first gantry is the entry node of the toll data, and the toll data is valid data. The toll data with missing entrance and exit times includes at least one gantry information, that is, the vehicle passes through at least one gantry in the target section and is recorded by the gantry. After the vehicle enters the target section from the highway interchange node or provincial boundary node, the vehicle will be recorded by the gantry, and the first gantry in the toll data of the vehicle is the gantry closest to the highway interchange node or provincial boundary node after entering the target section.

[0026] In some embodiments, when the toll data has the time of exiting the toll station but lacks the time of entering the toll station, if there are other gantries between the first gantry in the toll data and the nearest high-speed interchange node or provincial boundary node behind, the toll data is abnormal data. Alternatively, if there are other gantries between the last gantry in the toll data and the nearest high-speed interchange node or provincial boundary node in front, the toll data is abnormal data.

[0027] In some embodiments, if at least one of the entrance and exit times of the toll data is missing, if the exit node and / or the entry node can be determined based on the toll data of the toll gantry, the toll data is recorded as valid data, including: when the toll data is missing the time of exiting the toll station and the time of entering the toll station, if the toll data only includes one gantry, and the gantry is the only gantry between two adjacent nodes, and the nodes include high-speed interchange nodes and provincial boundary nodes, then the nodes adjacent to both sides of the gantry are the entry node and exit node of the toll data, and the toll data is valid data; otherwise, the toll data is abnormal data. The target road section is generally equipped with multiple gantries. When the toll data of the target road section only includes one gantry for the vehicle, and the gantry is the only gantry between two adjacent nodes, it can be considered that the vehicle enters from one of the two adjacent nodes and exits from the other. For example, there is only a first gantry between the provincial boundary node and the first expressway interchange node. If the charging data of the vehicle only includes the first gantry, that is, it is only recorded by the first gantry, and not recorded by other gantries on the target section, such as the second gantry, the third gantry, etc., then it can be considered that the vehicle enters the target section from one of the provincial boundary node and the first expressway interchange node, and exits the target section from the other. The vehicle's driving direction can be determined based on the charging data of the gantry, so the entry node and the exit node can be determined. For example, if the charging data of the first gantry determines that the vehicle enters the target section from the provincial boundary, then the vehicle enters from the provincial boundary node and exits from the first expressway interchange node. Conversely, the vehicle enters the target section from the provincial boundary node and exits the target section from the first expressway node.

[0028] In some embodiments, when the toll data lacks the time of exiting the toll station and the time of entering the toll station, if the toll data includes at least two gantries, and the first gantry in the toll data is the gantry closest to the high-speed interchange node or provincial boundary node behind, and the last gantry in the toll data is the gantry closest to the high-speed interchange node or provincial boundary node in front, then the high-speed interchange node or provincial boundary node closest to the first gantry is the entry node of the toll data, and the high-speed interchange node or provincial boundary node closest to the last gantry is the exit node of the toll data, and the toll data is valid data; otherwise, the toll data is abnormal data. The target road section is generally provided with multiple gantries. When the toll data of the target road section includes at least two gantries, if the first gantry in the toll data is the gantry closest to the high-speed interchange node or provincial boundary node behind, it can be considered that the vehicle enters from the high-speed interchange node or provincial boundary node behind the first gantry, and the node can be used as the starting point of the vehicle in the target road section. After the vehicle enters from the node, it is recorded by the first gantry. If the last gantry in the toll data is the gantry closest to the highway interchange node or provincial boundary node ahead, it can be considered that the vehicle exited from the highway interchange node or provincial boundary node in front of the last gantry, and this node can be used as the end point of the vehicle on the target section.

[0029] For example, there are a first gantry and a second gantry between the provincial boundary node and the first expressway interchange node, the first gantry is close to the provincial boundary node, and the second gantry is close to the first expressway interchange node. If the first gantry in the vehicle's charging data is the first gantry and the last gantry is the second gantry, it can be considered that the vehicle enters the target section from the provincial boundary node and exits the target section from the first expressway interchange node. If the first gantry in the vehicle's charging data is the second gantry and the last gantry is the first gantry, it can be considered that the vehicle enters the target section from the first expressway interchange node and exits the target section from the provincial boundary node.

[0030] In some embodiments, the method of the embodiment of the present application further includes: determining the starting and ending points of each valid data. The valid data can determine the nodes where the vehicle enters or exits the target section, thereby determining the starting and ending points of the vehicle on the target section.

[0031] The starting and ending points of the toll data with complete entry and exit times are the toll station for entering the target road section and the toll station for exiting the target road section. If the toll data includes the toll stations for entering and exiting the target road section, the starting point is the toll station for entering the target road section, and the end point is the toll station for exiting the target road section.

[0032] The starting point of valid data with the time of entering the toll station but missing the time of exiting the toll station is the toll station entering the target section, and the end point is the nearest exit node in front of the last gantry in the valid data. For valid data missing from the toll station, the node where the vehicle exits the target section can be determined based on the gantry, and this node is the end point of the vehicle's journey on the target section. The node where the vehicle exits can be a highway interchange node or a provincial boundary node.

[0033] The starting point of valid data with the time of exiting the toll station but missing the time of entering the toll station is the nearest entry node behind the first gantry in the valid data, and the end point is the toll station exiting the target section. For valid data missing the entry toll station, the node where the vehicle enters the target section can be determined based on the gantry, and this node is the starting point of the vehicle's journey on the target section. The node entered by the vehicle can be a highway interchange node or a provincial boundary node.

[0034] In valid data with missing entrance and exit times, if the valid data includes at least two gantries, the starting point is the nearest entry node behind the first gantry, and the end point is the nearest exit node in front of the last gantry. For valid data missing for both entry and exit toll stations, the node where the vehicle enters the target section can be determined based on the first gantry in the valid data, and this node is the starting point of the vehicle's journey on the target section. The node where the vehicle exits the target section can be determined based on the last gantry in the valid data, and this node is the end point of the vehicle's journey on the target section. The nodes where the vehicle enters and exits can be high-speed interchange nodes or provincial boundary nodes.

[0035] For valid data with missing entry and exit times, if the valid data only includes one gantry, the starting point is the nearest entry node behind the gantry, and the end point is the nearest exit node in front of the gantry. For valid data with missing entry and exit toll stations, the nodes where the vehicle enters and exits the target section can be determined based on the unique gantry, which are used as the starting point and end point of the vehicle's journey on the target section. The node entered by the vehicle can be a high-speed interchange node or a provincial boundary node.

[0036] In some embodiments, the method of the embodiment of the present application further includes: analyzing the travel characteristics of the target road section based on the valid data, the travel characteristics include travel type, travel time, travel duration and travel space. The charging data includes the start and end time, and the travel time and travel duration of each vehicle on the target road section can be determined, and the travel type and travel space can be analyzed based on the start and end points.

[0037] For valid data missing from the entrance and exit time, the time when the vehicle enters and / or leaves the target section can be determined based on the time information in the toll data recorded by the corresponding gantry. For example, the time recorded by the corresponding gantry can be directly used as the time when the vehicle enters and / or leaves the target section. Alternatively, the time from the gantry to the entry node or exit node can be calculated based on the distance from the gantry to the entry node or exit node and the speed of the vehicle, and the calculated time can be subtracted or added to the time recorded by the corresponding gantry as the entry time or exit time.
