Problems solved by technology

However, the method cannot establish a suitable model for the estimation of driving time under the influence of various factors. At the same time, although the driving time of multiple road sections is considered, the correlation of auxiliary information such as road sections is ignored.
Therefore, the obtained travel time estimation data may not have high accuracy

Abstract

The present invention provides a driving time estimation system based on traffic flow grading, which includes: traffic flow data hardware perception layer, including terminal nodes and data collection and transmission modules; cloud service layer, including cloud database and cloud server deployed in the cloud, cloud database It is used to save the data generated by the vehicle during driving, and the cloud server includes: road condition zoning system; road condition sub-area grading system; road condition sub-area section travel time evaluation system and travel time acquisition system. The present invention can collect traffic flow influence data from multiple angles, partition traffic conditions based on multi-source data, and then estimate travel time based on partition results, considering the coupling relationship of travel time of each partition path, and is especially suitable for driving during peak hours time judgment.

Description

Technical field [0001] The present invention relates to the field of intelligent transportation technology, in particular, to a travel time estimation system based on traffic flow classification. Background [0002] In recent years, travel time estimation has been widely used in issues such as driving scheduling, user taxi and path navigation. By making a reasonable estimate of the driver's driving time, it can be very convenient for the vehicle to drive and improve the user experience. There are many factors that affect the driver's driving time, including driving distance, road type, driving habits, traffic conditions, etc.; driving time estimation is to study the role of the above factors to make a reasonable driving time estimation. However, the method is not very good at establishing a suitable model for the estimation of driving time under the influence of multiple factors, and although the driving time of multiple road sections is considered, the correlation of auxiliary ...
