Embodiment 1

[0119] Such as figure 2 As shown, a historical trajectory data processing method provided in Embodiment 1 of the present application includes:

[0120] S201: Obtain historical driving status information and historical order information uploaded by at least one terminal, where the historical order information includes an order identifier.

[0121] Specifically, the terminal may be a terminal used by a driver, or a terminal used by a passenger. Through the terminal used by the driver, the terminal uploads the driver's order information and the driving status information generated by the driver driving the vehicle. It is also possible to obtain the passenger's order information and the driving status information generated by the passenger's ride in the vehicle through the terminal used by the passenger.

[0122] The above driving status information and order information can be stored in the storage device of the terminal to form historical driving status information and histor...

Embodiment 2

[0147] Such as image 3 As shown, a historical trajectory data processing method provided in Embodiment 2 of the present application includes:

[0148] S301: Obtain historical driving status information that matches at least one target order identifier respectively, wherein the historical driving status information includes at least one of the following information: the position coordinates of each track point, the time passed by each track point, the time passed by each The velocity of the track point.

[0149] In the specific implementation process, the query request can be determined according to the analysis requirements, and the query request can be sent to the server, so as to receive the historical driving state information sent by the server. Specifically, it can be implemented through any of the following possible implementation modes:

[0150] A: Sending a first query request carrying at least one target order identifier to the server; receiving historical driving ...

Embodiment 3

[0223] Such as Figure 4 As shown, a historical trajectory data processing device 400 provided in the embodiment of the present application includes:

[0224] An acquisition module 401, configured to acquire historical driving status information and historical order information uploaded by at least one terminal, where the historical order information includes an order identifier;

[0225] The matching module 402 is used to match the historical driving state information corresponding to each terminal with the historical order information, and obtain the historical driving state information matched with each historical order executed by each terminal;

[0226] The first building module 403 is used to build a first database storing the mapping relationship between the order identifier of each historical order and the matching historical driving state information;

[0227] The query module 404 is configured to obtain, from the first database, historical travel status information ...

Abstract

The invention discloses a historical trajectory data processing method and device, and aims to analyze historical trajectory data more accurately by means of accurately, quickly and flexibly acquiringthe historical trajectory data. The historical trajectory data processing method comprises the steps of obtaining historical driving state information and historical order information uploaded by atleast one terminal, wherein the historical order information comprises an order identifier; matching the historical driving state information corresponding to each terminal with the historical order information, and constructing a first database storing a mapping relationship between the order identifier of each historical order and the matched historical driving state information; and when a query request carrying the first target order identifier sent by the request end is received, obtaining historical driving state information matched with the first target order identifier from the first database, and sending the obtained historical driving state information to the request end.

Description

technical field [0001] The present application relates to the technical field of data analysis, in particular, to a method and device for processing historical trajectory data. Background technique [0002] In order to optimize urban traffic and analyze urban traffic data such as traffic operation trends, locations of congestion, and traffic flow in different regions, it is necessary to obtain historical vehicle trajectory data of a specified time range and spatial range. Due to the large amount of historical vehicle trajectory data, there is a lack of means to combine vehicle historical trajectory information with travel conditions in the prior art, so it is impossible to accurately, quickly and flexibly obtain vehicle historical trajectory data, and thus cannot analyze vehicle historical trajectory data. data for accurate analysis. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present application is to provide a historical tra...
