Analysis of Subway Station Distribution Capacity Based on Automatic Fare Collection Data of Nanjing Metro
Publisher: ASCE
Abstract: To realize an early warning system for crowded subway passenger flow, a new calculation method of subway station distribution capacity (SSDC) in real time is proposed. First, a new concept of SSDC is defined according to ...
Vehicle Trajectory Reconstruction Incorporating Probe and Fixed Sensor Data
Publisher: ASCE
Abstract: Trajectory estimation is essential for obtaining a complete picture of traffic flow with limited and continuously detected traffic data, which are helpful in evaluating transportation performance and developing precise ...
Real-Time Optimization of Urban Rail Transit Train Scheduling via Advantage Actor–Critic Deep Reinforcement Learning
Publisher: American Society of Civil Engineers
Abstract: Under the condition of urban rail transit uncertainty of passenger demand and the high frequency of departure intervals, this study presents an innovative real-time urban rail transit (URT) train service scheduling control ...
Queue Length Estimation on Urban Signalized Intersection Combining Automatic Vehicle Identification and Vehicle Trajectory Data
Publisher: American Society of Civil Engineers
Abstract: Queue length is one of the indicators of the state of traffic and is often used to measure the operational state of signalized intersections. Many studies have proposed estimating queue length from vehicle trajectory data ...
Vehicle Trajectory Reconstruction from Sparse Data Using a Hybrid Approach
Publisher: American Society of Civil Engineers
Abstract: Vehicle trajectories deliver precious information, supporting traffic state estimation and congested traffic mitigation. However, collecting fully sampled vehicle trajectories is difficult due to unaffordable data-collection ...
Clustering Analysis of Ridership Patterns at Subway Stations: A Case in Nanjing, China
Publisher: American Society of Civil Engineers
Abstract: Better understanding of urban mass transit trip mobility patterns will be helpful to increase public transit ridership and improve transit services of large cities. Therefore, a station-oriented clustering analysis on ...
