Lateral Stability of a Ballasted Curved Track
(ASCE, 11/1/2020 )This paper investigates the status of lateral stability of a ballasted curved track, which is carried out under four loading scenarios in terms of the factor of safety against displacement as the indicator. Then, the ... -
Spatial Transferability Testing of Dummy Variable Winter Weather Model Using Traffic Data Collected from Five Geographically Dispersed Weigh-in-Motion Sites in Alberta Highway Systems
(ASCE, 11/1/2020 )It has been an engineering practice that highway agencies collect traffic data using highway traffic monitoring techniques such as permanent traffic counts (PTCs) and weigh in motion (WIM). This research used the WIM traffic ... -
Flexible Route Optimization for Demand-Responsive Public Transit Service
(ASCE, 12/1/2020 )Traditional customized buses travel on fixed routes, which cannot satisfy passengers’ flexibility and convenience requirements. This paper studies a demand-responsive transit (DRT) service that can continuously adjust the ... -
Modeling Operating Speed Using Continuous Speed Profiles on Two-Lane Rural Highways in India
(ASCE, 11/1/2020 )The geometric elements of the road, such as tangents and curves, play a vital role in road safety because significant crashes are reported on the horizontal curves and tangent-to-curve transitions. Literature reveals that ... -
Joint Optimization of Road Classification and Road Capacity for Urban Freight Transportation Networks
(ASCE, 10/1/2020 )In previous studies, almost all urban network design models/methods made attempts to optimize transportation system performance, such as minimizing road traffic congestion, by determining optimal road capacity expansion ... -
Effects of Line-Capacity Reductions on Urban Rail Transit System Service Performance
(ASCE, 10/1/2020 )In the daily operations of urban rail transit (URT) systems, line capacity sometimes is reduced, which worsens service performance. To measure the effects of line capacity reductions on URT system service performance in a ... -
Train Operation Diagram–Based Equilibrium Model for an Urban Rail Transit Network with Transfer Constraints
(ASCE, 11/1/2020 )For urban rail transit (URT) operation and management, it is important to accurately estimate the spatial and temporal passenger flow distribution spreading all over the network. Unfortunately, a literature review shows ... -
Preference Information Incorporation for Decision Making in the Biobjective Alignment Optimization Problem of River-Crossing Tunnels
(ASCE, 10/1/2020 )For a specific multiobjective tunnel alignment design problem, engineers have difficulty finding a suitable solution to satisfy a set of preference criteria. This paper presents a biobjective optimization approach incorporating ... -
Bus-Car Mode Identification: Traffic Condition–Based Random-Forests Method
(ASCE, 10/1/2020 )Travel mode identification is one of the key issues in travel behavior analysis. A number of algorithms have been proposed to detect travel modes particularly by using global positioning system (GPS) data, whereas most ... -
Guidance for Design and Implementation of Queue Jump Lane with Presignal for a Heterogeneous Traffic Environment
(ASCE, 10/1/2020 )In mixed traffic streams, especially near intersections, bus priority treatments are necessary to prevent buses from significant travel time losses. This paper aims to assist practitioners and field engineers to identify ... -
Investigation of Influential Variables to Predict Passing Rate at Short Passing Zones on Two-Lane Rural Highways
(ASCE, 10/1/2020 )The passing zone (PZ) is that part of two-lane highways in which drivers can safely overtake slower vehicles. Several studies have presented passing rate models in the PZ. However, there is no model to predict the passing ... -
Estimating Total Demand and Benchmarking Base Price for Student Parking on University Campuses
(ASCE, 10/1/2020 )Most universities limit the number of student parking permits and use their prices to moderate the parking demand. Two critical inputs for implementing such a practice are: (1) the total demand (number of students who ... -
Adoption of Exclusive and Pooled TNC Services in Singapore and the US
(ASCE, 9/1/2020 1)On-demand mobility services provided by transport network companies (TNCs) have experienced significant growth in their adoption and diversification of services in major metropolitan cities around the world. This study ... -
Methodology to Estimate the Need for Direct-Current Fast-Charging Stations along Highways in Canada
(ASCE, 10/1/2020 )Many research works have focused on solving facility location problems to optimize the distribution of direct current fast charging (DCFC) stations along highways. However, before such optimization studies can be done, a ... -
Modeling and Prediction of Bus Operation States for Bunching Analysis
(ASCE, 9/1/2020 1)Bus bunching deteriorates transit service quality and passengers’ experience. The modeling and prediction of bus operation states are essential for improving the quality of transit service. Due to the nature of traffic ... -
Short-Term Speed Prediction for Expressway Considering Adaptive Selection of Spatiotemporal Dimensions and Similar Traffic Features
(ASCE, 10/1/2020 )Drivers on the expressway prefer to acquire more traffic information so they can select the best driving route and avoid a traffic jam. Therefore, it is necessary to conduct a study about real-time speed prediction and ... -
Impact of Adverse Weather on Freeway Bottleneck Performance
(ASCE, 10/1/2020 )Congestion on freeways occurs when demand exceeds the available capacity. Common causes of recurring congestion, also known as freeway bottlenecks, include lane drops, on-ramp merges, and weaving sections. Adverse weather ... -
Ballast Condition Monitoring for Turnouts Using Power Spectral Density
