Traffic Models

Traffic Performance of Successive Freeway Merge Segments

At freeway interchanges with high entering flows, implementing two successive merges can improve traffic flow and capacity by distributing the merging maneuvers. The German Guidelines for the Design … [Read more...] about Traffic Performance of Successive Freeway Merge Segments

Framework for Assessing Bridges Construction Impact on Work Zone Traffic Using BrIM

This research presents a framework for visualizing bridge construction impact on work zone traffic using Bridge Information Modelling (BrIM) and Google Maps API. The framework consists of four … [Read more...] about Framework for Assessing Bridges Construction Impact on Work Zone Traffic Using BrIM

Simulation of Roadside LiDAR Applications: A Smart Work Zone Case Study

Light detection and ranging (LiDAR) have the capability to detect 360-degree surrounding objects with high accuracy (centimeter level), high frequency (a tenth of a second), and long measuring … [Read more...] about Simulation of Roadside LiDAR Applications: A Smart Work Zone Case Study

Safety and Mobility Analysis of Rolling Slowdown for Work Zones: Comparison with Full Closure

There are times when the traffic lanes through a work zone must be kept clear for activities such as placing overhead beams, erecting overhead signs, and installing power lines, and other temporary … [Read more...] about Safety and Mobility Analysis of Rolling Slowdown for Work Zones: Comparison with Full Closure

Method for Estimating Capacity and Measures of Effectiveness of Two-Lane Highway Work Zones

The present study proposes a method for determining the capacity and measures of effectiveness of two-lane highway work zones. Therefore, a deterministic mathematical formulation was developed based … [Read more...] about Method for Estimating Capacity and Measures of Effectiveness of Two-Lane Highway Work Zones

Quantitatively Evaluate Work Zone Driver Behavior Using 2D Imaging, 3D LiDAR, and Artificial Intelligence in Support of Congestion Mitigation Model Calibration and Validation

This project addressed the following: 1) a lack of a system to process raw traffic footage obtained from work zones to extract traffic and driver behavior information, especially systems that leverage … [Read more...] about Quantitatively Evaluate Work Zone Driver Behavior Using 2D Imaging, 3D LiDAR, and Artificial Intelligence in Support of Congestion Mitigation Model Calibration and Validation
