Modeling Merging Acceleration and Deceleration Behavior Based on Gradient-Boosting Decision Tree
(ASCE, 7/1/2020 1)This paper aims to model the behavior of merging acceleration/deceleration when cars are running in a congested weaving section on a freeway during the merging implementation period by using a data-driven method called ... -
Real-Time Movement-Based Traffic Volume Prediction at Signalized Intersections
(ASCE, 8/1/2020 1)The traffic volume of each movement at signalized intersections can provide valuable information on real-time traffic conditions that enable traffic control systems to dynamically respond to the fluctuated traffic demands. ... -
Utilizing Low-Ping Frequency Vehicle Trajectory Data to Characterize Delay at Traffic Signals
(ASCE, 8/1/2020 1)Probe vehicle data is changing the landscape of transportation engineering. The availability of vehicle trajectory data, or GPS waypoint data, has expanded the utility of probe data. However, the low penetration rate of ... -
Case Study: Economic Analysis of Statewide Roadway 3D Mapping Using Mobile LiDAR
(ASCE, 7/1/2020 1)The Oregon Department of Transportation (ODOT) has been using survey-grade mobile Light Detection and Ranging (LiDAR) technology to scan and create three-dimensional (3D) representations of its more than 12,880 km of ... -
Crash Severity Analysis for Low-Speed Roads Using Structural Equation Modeling Considering Shoulder- and Pavement-Distress Conditions
(ASCE, 7/1/2020 1)Crash severity outcomes are random and are influenced by the interactions of vehicle, driver, crash, road, and environmental factors. Limited research has attempted to assess the direct and latent influence of road factors ... -
Leveraging Connected Vehicles to Provide Enhanced Roadway Condition Information
(ASCE, 8/1/2020 1)Real-time performance measures are important for agencies to maintain their roadways during the winter season. However, infrastructure can be expensive to deploy and maintain and may be sparse in rural areas, while speed ... -
Impact of Fog Conditions on Lane-Level Speeds on Freeways
(ASCE, 9/1/2020 1)Few studies have focused on the impacts of fog conditions on lane-based speeds on freeways. To explore speed differences and to predict speeds under fog conditions, this paper analyzed the historical traffic data and ... -
Travel-Time Variability Analysis of Bus Rapid Transit System Using GPS Data
(ASCE, 6/1/2020 1)In prior studies, the transit service reliability has been looked at from the passenger’s perspective in terms of time spent by the passengers in waiting for their bus to arrive at a stop. The operators’/agencies’ perspective ... -
Effect of Construction Work Zone on Traffic Stream Parameters Using Vehicular Trajectory Data under Mixed Traffic Conditions
(ASCE, 6/1/2020 1)The research work presented is originated with the intent of studying driving behavior, especially in a lateral direction under the influence of construction work activities under prevailing heterogeneous traffic conditions. ... -
Applying Finite Mixture Models to New York City Travel Times
(ASCE, 5/1/2020 1)The distribution of travel times in high density urban environments is observed to be multimodal as a result of random demand fluctuations, nonrecurrent incidents, and other interruptions. Conventional travel time measures ... -
Micro- and Macroapproach to Modeling Relationship between Control and Stopped Delays at Signalized Intersections
(ASCE, 1/1/2020 1)Control delay, the most important measure of effectiveness at signalized intersections, is commonly estimated using analytical models due to the difficulty of field measurements. In analytical models, the uniform component ... -
Speed, Fatigue Test, and P2 Load Limit: Fatigue Strength of Railroad Rail
(ASCE, 1/1/2020 1)The allowable bending fatigue stress in a rail will determine the maximum allowable speed, which is then checked against the current operating speed. Therefore, some sensible value of allowable bending fatigue stress must ... -
Data Fusion Approach for Evaluating Route Choice Models in Large-Scale Complex Urban Rail Transit Networks
(ASCE, 1/1/2020 1)With the increases in both the urban rail transit (URT) network scale and complexity, a route choice model that was previously developed may not function properly anymore and therefore must be constantly evaluated if ... -
