Problems solved by technology

At present, relevant research and applications are mostly based on relational databases (such as oracle, SqlServer) using the relationship between data to actively discover the relationship and organize the data. In this way, some hidden and imperceptible relationships are easy to be ignored.
In addition, some scholars and applications organize and analyze data based on machine learning algorithms, but they require a large amount of labeled data and complex feature engineering.

Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0053] Aiming at the problems existing in the prior art, the present invention utilizes the widely existing bayonet data (the vehicle is detected when passing the vehicle, and the detection content includes the license plate number, the time of passing the vehicle, and the location of the vehicle passing). Then, the entity relationship of the traffic travel knowledge map is transformed into a Markov logic network, and the bottom-up structural learning method is adopted to mine the temporal and spatial association rules of traffic travel, and then the information that needs ...

Abstract

The invention discloses a travel map-based vehicle destination prediction method, a device, equipment and a medium. The method comprises the steps of obtaining a gate; constructing a traffic map according to the checkpoint data; converting an entity relationship in the traffic travel map into a Markov logic network; mining the traffic travel map to obtain a traffic travel time-space association rule; converting the Markov logic network into an instantiated Markov network; and determining a destination prediction result of the individual vehicle according to the traffic travel time-space association rule and the Markov network. The method can improve the accuracy of individual vehicle travel destination speculation, improves the speculation efficiency, and can be widely applied to the technical field of traffic data processing.

Description

technical field [0001] The invention relates to the technical field of traffic data processing, in particular to a vehicle destination prediction method, device, equipment and medium based on a travel map. Background technique [0002] Destination estimation of individual vehicles is one of the core parts of the current intelligent transportation system, which plays an important role in supporting and guiding the management and decision-making of the overall transportation system. Based on the accurate and effective prediction results of individual vehicle travel destinations, through the interaction of traffic decision-making, traffic guidance and the overall urban road network and closely cooperating with the actual conditions of people, vehicles, and roads, the efficiency of transportation can be effectively improved and traffic congestion can be alleviated. Improving the traffic capacity of the road network, the driving speed of the road section and the traffic experienc...
