Mixed Traffic Flow Signal Timing Optimization Method Considering E-Bike Expansion Influence
(ASCE, 2/1/2021)The increase in e-bikes has aggravated traffic conflicts and casualties at intersections. However, existing signal control methods focus on motor vehicles, ignoring the influence of expansion behavior of e-bikes on motor ... -
Calibrating Microscopic Car-Following Models for Adaptive Cruise Control Vehicles: Multiobjective Approach
(ASCE, 1/1/2021)Adaptive cruise control (ACC) vehicles are the first step toward comprehensive vehicle automation. However, the impacts of such vehicles on the underlying traffic flow are not yet clear. Therefore, it is of interest to ... -
Evacuation Traffic Management under Low Visibility and Toxic-Gas Leakage Disasters
(ASCE, 1/1/2021)The majority of existing evacuation models neglect the fact that leaking toxic gas usually degrades atmospheric visibility under chemical disasters. This paper takes the impact of leaking toxic gas on atmospheric visibility ... -
Exploring the Spatially Heterogeneous Effects of Urban Built Environment on Road Travel Time Variability
(ASCE, 1/1/2021)Most studies of road travel time estimation have been based on traffic-flow theory or data-driven methods and generally neglect the influence of urban built environment on road travel time. A global regression model and a ... -
From Driving Simulator Experiments to Field-Traffic Application: Improving the Transferability of Car-Following Models
(ASCE, 1/1/2021)Over the last few decades, there have been two main streams of data used for driving behavior research: trajectory data collected from the field [such as using video recordings and global positioning systems (GPS)] and ... -
Innovative Methods for Delivering Fresh Food to Underserved Populations
(ASCE, 1/1/2021)This study analyzed a last-mile fresh food delivery system for individuals in underserved communities. Five alternative delivery networks with various modes were considered: conventional trucks, electric cargo bikes, ... -
Sensitivity Analysis of Maximum Weaving Length for One-Sided Weaving Section Based on <i>HCM</i> <i>2016</i>
(ASCE, 1/1/2021)As explained in the Highway Capacity Manual (HCM), if the segment length is greater than the maximum weaving length (Lwmax), it is considered to be separate segments of merging and diverging; otherwise, it is a weaving ... -
Methodology for Risk Ranking of At-Grade Intersections on Existing Rural Two-Lane Highways
(ASCE, 2/1/2021)The objective of this paper is the creation of a suitable methodology capable of deploying elements that characterize the existing infrastructure on rural two-lane highways regarding the location and geometric features of ... -
Evaluating the Wheelset Health Status of Rail Transit Vehicles: Synthesis of Wear Mechanism and Data-Driven Analysis
(ASCE, 12/1/2020 )The security and reliability of rail transit vehicles in service are greatly affected by their wheel–rail contact. Thus, modeling the wear of wheelsets and monitoring their status is important for improving safety and ... -
Safety Performance Evaluation of the New Mega Elliptical Roundabout Interchanges Using the Surrogate Safety Assessment Model
(ASCE, 12/1/2020 )Mega elliptical roundabouts are considered a new kind of intersection and can be found on rural multilane highways. Their form is that of an elongated ellipse. They combine the best advantages of an unconventional median ... -
Influence of Priority Violations on Entry Capacity at Roundabouts
(ASCE, 12/1/2020 )The gap acceptance theory, which is widely used for capacity analysis of roundabouts, assumes absolute priority to circulating vehicles over entry vehicles. Priority violations such as priority reversal and limited priority ... -
New Headway-Based Analytical Capacity Model Considering Heterogeneous Train Traffic
(ASCE, 12/1/2020 )Assessing the railway capacity of a rail network wherein a few types of trains operate with various halting patterns is very difficult, because the headway greatly varies depending on the order in which trains of different ... -
Investigating the Impact of Rain on Crash-Clearance Duration
(ASCE, 11/1/2020 )Crashes are one of the major causes of traffic delays. It is therefore essential to clear crashes as quickly as possible. However, adverse weather conditions, especially rainy conditions, could potentially influence crash ... -
Toll Plaza Lane Choice and Lane Configuration Strategy for Autonomous Vehicles in Mixed Traffic
(ASCE, 12/1/2020 )Toll plazas are one kind of highway node that pose a challenge to the flow of autonomous vehicles (AVs). Some toll roads have open road tolling (ORT), which makes it easier and more efficient for AVs, but most toll plazas ... -
Modeling Travelers’ Acceptance of Variable Message Signs: A Hierarchical Hybrid Choice Model
(ASCE, 12/1/2020 )This study aims to develop a framework that integrates the technology acceptance model (TAM) into a route-switching model of travelers’ response to variable message signs (VMS). In addition to the parsimonious TAM constructs ... -
Freeway Traffic Speed Estimation by Regression Machine-Learning Techniques Using Probe Vehicle and Sensor Detector Data
(ASCE, 12/1/2020 )In the literature, machine-learning techniques have been extensively implemented to capture the stochastic characteristics of freeway traffic speed. The deployment of intelligent transportation systems (ITSs) in recent ... -
Underground Metro Interstation Horizontal-Alignment Optimization with an Augmented Rapidly Exploring Random-Tree Connect Algorithm
(ASCE, 11/1/2020 )The design of an underground metro alignment in an urban area is complex and challenging. The metro alignment constantly invades districts with high-density buildings and specially planned districts, which results in large ... -
