By accurately predicting the short-term road traffic information in the future, it can effectively improve the traffic efficiency of vehicles in a specific period. In this paper, data training is carried out according to the collected relevant indicators, and a decision tree classification model is established. The model can be used to predict the traffic flow on the road in a short period of time based on the time of the road, weather, average speed, and other indicators, and then the relevant regulatory authorities can use the advanced new media today to push, so that the citizens can plan their trips reasonably.</li></ul>/MT/paperinfo/56625.shtmlModern Transportation/MT/paperinfo/56625.shtml2021-0<p class="abstract">Issues on Application of Portable Pilot Units</p><ul><li>Pages 7-13</li><li>Author Shengqin Zhan</li><li>Abstract Portable Pilot Units (PPU) play an important role in modern pilotage. With more than 20 years’ PPU development and practice, a comprehensive data analysis is conducted in this paper. The reliabilities and accuracy of different sensors are compared. Finally, the risk of PPU piloting and the corresponding countermeasures is discussed.</li></ul>/MT/paperinfo/56669.shtmlModern Transportation/MT/paperinfo/56669.shtml
