Car-Following Model Based on Deep Learning and Markov Theory
(ASCE, 9/1/2020 1)A car-following (CF) model can reproduce various micro traffic phenomena and plays a crucial role in traffic theory. In this study, we combine Markov theory and a gated recurrent unit (GRU) neural network (NN) to propose ... -
Estimating Sectional Volume of Travelers Based on Mobile Phone Data
(ASCE, 10/1/2020 )The sectional volume of travelers refers to the number of travelers crossing a section boundary (e.g., river, mountain, railway line, etc.) within a certain time period. Mobile phone data provides continuous and ... -
Modeling Two-Lane Highway Passing-Related Crashes Using Mixed Ordinal Probit Regression
(ASCE, 9/1/2020 1)One of the crucial areas in road safety is that of passing-related crashes on two-lane highways. Studies have shown that passing-related crashes that occurred due to inadequate passing sight distances were uncommon, ... -
Car-Following Characteristics of Adaptive Cruise Control from Empirical Data
(ASCE, 9/1/2020 1)Computer-driven vehicles will behave differently from human-driven vehicles due to changes in perception abilities, precision control, and reaction times. These changes are expected to have profound impacts on capacity, ... -
Modeling and Evaluating Public Transit Equity and Accessibility by Integrating General Transit Feed Specification Data: Case Study of the City of Charlotte
(ASCE, 10/1/2020 )This study models and evaluates the accessibility to public transit and public transit equity by integrating the general transit feed specification (GTFS) data. A transit gap index (TGI) and a geographic information system ... -
Analyzing Factors that Influence Expressway Traffic Crashes Based on Association Rules: Using the Shaoyang–Xinhuang Section of the Shanghai–Kunming Expressway as an Example
(ASCE, 9/1/2020 1)Analyzing the influencing factors in expressway traffic crashes is an important aspect of traffic safety analysis. This study examines detailed data from 217 crashes that took place from 2015 to 2016 on the Shaoyang–Xinhuang ... -
Probabilistic Methodology to Quantify User Delay Costs for Urban Arterial Work Zones
(ASCE, 9/1/2020 1)The total cost of road construction comprises direct costs paid by agencies and indirect costs paid by road users. In densely populated urban areas, work zone instigated user costs could outweigh direct costs and therefore ... -
Vehicle Delay Modeling at Signalized Intersections with Gene-Expression Programming
(ASCE, 9/1/2020 1)The accurate determination of vehicle delays is crucial for effective intersection management. Because the optimization of signal duration in a signalized intersection is based on the reduction of delays, the rapid and ... -
Reconfiguring Urban Undivided Four-Lane Highways to Five-Lane: A Nonideal but Very Effective Solution for Crash Reduction
(ASCE, 10/1/2020 )Although a reconfiguration to three-lane with a left turn lane remains the most prevalent cost-effective countermeasure, some four-lane undivided highway segments in Louisiana have been reconfigured to five-lane segments ... -
Deriving Pedestrian Risk Index by Vehicle Type and Road Geometry at Midblock Crosswalks under Heterogeneous Traffic Conditions
(ASCE, 10/1/2020 )Pedestrian crash data are not available in sufficiently large quantity and suffer from known problems such as a low-mean small sample, underreporting, and misclassification. Moreover, under heterogeneous traffic conditions, ... -
Image-Based Approach for Parking-Spot Detection with Occlusion Handling
(ASCE, 9/1/2020 1)With the aid of advanced information technology, car parking space management is evolving dramatically toward an automatic way. The most efficient approach for parking-spot detection is based on embedded sensors, which can ... -
Impacts of Directional Rumble Strips on Vehicle Speeds and Driver Behavior at Freeway Off-Ramps
(ASCE, 9/1/2020 1)Drivers have an increased crash or incident risk when driving on freeway interchange ramps compared with the other interchange-related segments. Directional rumble strips (DRS), a pattern similar to the traditional traversable ... -
Evaluating Spatial Justice in Rail Transit: Access to Terminals by Foot
(ASCE, 9/1/2020 1)There has been a growing interest to improve urban rail services for increasing a city’s economic competitiveness. While accessibility provided by rail services has been the focus of many studies, determining accessibility ... -
Edge-Based Traffic Flow Data Collection Method Using Onboard Monocular Camera
(ASCE, 9/1/2020 1)Traffic data collection is the fundamental step in most applications of intelligent transportation systems (ITS). Recently, traffic data collection methods have become more robust and diversified, yet still have some ... -
Reliability Measure-Based Data Analytics Approach to Identifying and Ranking Recurrent Bottlenecks in Urban Rail Transit Networks
(ASCE, 9/1/2020 1)Recurrent bottlenecks in the urban rail transit (URT) system during rush hours have become a significant concern for both passengers and URT operators. In order to alleviate the resulting peak-hour congestion in urban rail ... -
Optimizing a High-Speed Railway Operation Plan Based on Train Capacity and Service Frequency
(ASCE, 10/1/2020 )In this paper, a model to optimize a high-speed railway operation plan by dividing it into a train route plan and train stop schedule plan was developed based on the train capacity and service frequency. To capture the ... -
Field Implementation of Directional Rumble Strips to Deter Wrong-Way Driving on Freeways
