Bus Arriving Time Prediction Based On Road Context

With the development of urban development,the increasing number of urban population and vehicles has aggravated the situation of traffic congestion and further aggravated environmental pollution.In order to solve these problems,the governme nt has vigorously built a public transportation system and recommended buses as its preferred mode of travel.However,in real life,factors such as real-time traffic conditions,weather conditions,changes in the traffic lights,and the location of bus stops can affect the normal driving of buses.These will lead to greater errors in the prediction of bus arrival time and affect people's normal travel.Therefore,the importance of real-time bus arrival forecasting has become increasingly apparent and has received widespread attention at home and abroad.In reality,the bus is not a single individual,and its driving will be constrained by other factors.Among various factors,the impact of road traffic on the bus is particular ly important.Considering the impact of road conditions on bus arrival time,it is of great significance to improve the bus-to-station time prediction model.Firstly,you need to obtain bus positioning data and preprocess the data.In order to ensure the reliability and accuracy of the data,the positioning data of the GPS device is used.Then filter out the wrong data,define the bus line information format,and build the basic characteristics of the bus line.Secondly,it explores the influence of different influencing factors on the accuracy of bus arrival time prediction.When buses travel along a specified route on the road,factors such as real-time traffic conditions,road congestion,the time at which the traffic lights are changing,and the location of bus stops can affect the normal driving of buses.This article classifies these factors as a whole and defines road context information.At the same time,the road context information is quantified and coded as a feature that influences the prediction of the bus arrival time and is combined with the basic features of the bus route to train and improve the forecast results.The bus arrival time forecast can provide important information for passengers' travel planning,and actively promotes the scientific development of urban public transport and the intelligent management of public transport,which not only has research significance but also has application significance.
