市域快轨快慢车模式越行节省时间研究OA北大核心

Different from the metro system,urban rapid rail is a newly constructed system of urban rail transit to meet the needs of commuting,large capacity,and fast speed,and express and slow train operation mode is imperative.Therefore,based on the existing research,considering the operation mode,overtaking speed,overtaking station type,turnout type,and other factors,the calculation method of the time saving of urban rapid rail overtaking under the express and slow train mode was researched and formed.The simulation model was built based on a domestic urban rapid rail,and the theoretical calculation results were verified by OpenTrack.The results show that when the overtaking speed is between 60 to 120 km/h,under the tracking mode,every skipping of the express train which turns to skip station operation saves 37～55 s compared with the slow train stopping(stopping time is included);under the overtaking mode,every overtaking of the express which turns to overtaking operation saves 69～87 s compared with the slow train stopping(stopping time is included).Compared to the simulation results,the average error of the theoretical calculation is within 3%.The research results can provide a reference for analyzing the time benefit of the express and slow train operation of urban rapid rail.
