Spatial–Temporal Model to Identify the Deformation of Underlying High-Speed Railway Infrastructure
(ASCE, 8/1/2020 1)Railway track geometry is generally understood to be influenced by the deformation of the track infrastructure. This study developed a spatial–temporal identification model for the deformation of the underlying high-speed ... -
Integration of Microsimulation and Optimized Autonomous Intersection Management
(ASCE, 9/1/2020 1)Autonomous intersection management (AIM) is a type of intersection control for autonomous vehicles which eliminates the need for a traffic signal by using vehicle-to-infrastructure communication. Vehicles communicate ... -
Gap Detection of Switch Machines in Complex Environment Based on Object Detection and Image Processing
(ASCE, 8/1/2020 1)A turnout, a device to guide tracks, is critical to the safety of high-speed railways. Detecting gaps in switch machines can monitor a turnout’s working performance. Existing gap-detection systems, however, can barely ... -
Novel Crash Surrogate Measure for Freeways
(ASCE, 8/1/2020 1)In this paper, a disturbance-based methodology was proposed to represent the safety level of a car-following scenario. According to the probabilistic causal model, the following vehicles always take evasive actions to avoid ... -
Modeling for Left-Lane Line Extensions at Signalized Intersections with Permitted Left-Turning Phase
(ASCE, 8/1/2020 1)At a signalized intersection with a permitted left-turning phase, left-turning and opposing through vehicles always compete for priority according to actual traffic conditions instead of following strict priority rules. ... -
Potential for Moving Blocks and Train Fleets to Enable Faster Train Meets on Single-Track Rail Corridors
(ASCE, 8/1/2020 1)On single-track rail corridors, meets between trains are a significant source of train delay. From the stopping train’s perspective, a meet can be divided into three distinct phases: braking into a siding, waiting for ... -
Categorizing Car-Following Behaviors: Wavelet-Based Time Series Clustering Approach
(ASCE, 8/1/2020 1)The categorization analysis of car-following behaviors is beneficial to enrich the current car-following models and the applications of connected and automated vehicles (CAVs) in a mixed traffic environment. Previous studies ... -
Recursive Hybrid Heuristic Algorithm for Routing a Track-Geometry Car through a Large-Scale Urban Subway Network
(ASCE, 8/1/2020 1)Rail track inspection is essential to urban rail infrastructure management in terms of safety. The track geometry car is one of the important inspection vehicles for track condition measurement. Routing a track geometry ... -
Pedestrian Spatial Violation Analyses for Urban Roadways
(ASCE, 11/1/2020 )This study presents an investigation regarding the critical contributing factors in pedestrian spatial violations based on field observation of 15,090 samples at 14 roadway segments in Shanghai, China. A violation prediction ... -
Bicycle Ridership Using Crowdsourced Data: Ordered Probit Model Approach
(ASCE, 8/1/2020 1)Cycling is a healthier and greener travel mode that city planners and policymakers have encouraged for short-distance trips. Because cycling provides an efficient way to improve public health and reduce energy consumption, ... -
Characteristic Analysis and Prediction of Traffic Accidents in the Multiethnic Plateau Mountain Area
(ASCE, 8/1/2020 1)This paper analyzes the distribution characteristics and influencing factors of traffic accidents in the multiethnic-gathering plateau mountain area. Using data from an investigation of 56,651 accident records in Guiyang, ... -
Forecasting Truck Parking Using Fourier Transformations
(ASCE, 8/1/2020 1)Truck-based transportation is the predominant mode used to transport goods and raw materials within the United States. While trucks play a major role in local commerce, a significant portion of truck activity is also long ... -
Adaptive Real-Time Prediction Model for Short-Term Traffic Flow Uncertainty
(ASCE, 8/1/2020 1)In order to promote the accuracy of short-term traffic flow forecasting, an adaptive real-time model consisting of two important stages is proposed. The first stage encloses a novel online sequence extreme learning machine ... -
