Method and device for obtaining bus station location

Abstract

Embodiments of the present invention provide a bus stop location acquisition method and device. The method includes: performing feature extraction on the state parameters of the ridge segment of the target bus line and the vehicle status data in the ridge segment to obtain the feature data of the ridge segment; The feature data is input into the preset machine learning network model, and based on the output results of the machine learning network model, it is determined whether the target bus line has a bus stop on the ridge segment; among them, the machine learning network model is based on the result label of the known bus stop The ridge segment samples are obtained after training. The ridge segment is the target bus line divided according to the preset distance. The vehicles in the vehicle status data include public transportation vehicles and / or social vehicles. This method can be implemented through the positioning data of bus vehicles and relatively small road network data, and by selecting characteristic data that conforms to the business knowledge field. It effectively reduces the cost of machine learning algorithm training, and the model performance is reliable and the engineering implementation is simple.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to a method and device for acquiring the location of a bus station. Background technique [0002] With the acceleration of urbanization in our country, the problem of urban traffic congestion has been aggravated. The development of public transportation is of great significance to the development of the city's transportation system. At present, the number of daily bus trips nationwide has reached 250 million. Under this background, real-time bus products for the public have emerged. Such data-driven products require data maintenance staff to maintain and update the basic data of the large-scale bus network in multiple cities, so as to provide users with reliable real-time bus information. [0003] Because the bus service department will adjust and set up bus midway stations according to municipal construction, passenger flow demand, urban planning and ot...

AI Technical Summary

Problems solved by technology

[0003] Because the bus service department will adjust and set up bus midway stations according to reasons such as municipal construction, passenger flow demand, and urban planning, this situation will cause data maintenance personnel to receive a large number of user feedback every day

Faced with this situation, data maintenance personnel need to screen and check the stations of a large number of lines every day, and then deduce the location of possible bus stops. This kind of work method is inefficient and expensive
