Traffic Data

Vehicle Collision Risk Assessment Method in Highway Work Zone Based on Trajectory Data

This study aims to evaluate vehicle safety in highway work zones by analyzing collision risk using vehicle trajectory data collected from these zones. First, vehicle movement within the work zone is … [Read more...] about Vehicle Collision Risk Assessment Method in Highway Work Zone Based on Trajectory Data

Evaluating Traffic Conflicts and Crash Risk in Nighttime Maintenance Operation Areas of Highways Using Vehicles’ Trajectory Data

Highway pavement maintenance operations are increasingly conducted at night, when lane reduction combined with the complexity of nighttime conditions elevates driving risks within maintenance … [Read more...] about Evaluating Traffic Conflicts and Crash Risk in Nighttime Maintenance Operation Areas of Highways Using Vehicles’ Trajectory Data

Effect of Construction Work Zone on Rear-End Conflicts by Vehicle Type Under Heterogeneous Traffic Conditions

Road transportation is a critical mode of transportation because of its mobility characteristics. Road construction work zones (WZ) are widespread on roads because of increased travel demand. Thus, it … [Read more...] about Effect of Construction Work Zone on Rear-End Conflicts by Vehicle Type Under Heterogeneous Traffic Conditions

Queue Analysis at Work Zones From Field-Collected Data

Estimation of the capacity of work zones is vital to manage the possibility of traffic flows exceeding capacity and resulting in unbearable queues during work zone lane closures. A plethora of … [Read more...] about Queue Analysis at Work Zones From Field-Collected Data

Crash Prediction for Freeway Work Zones in Real Time: A Comparison Between Convolutional Neural Network and Binary Logistic Regression Model

Safety of drivers in freeway work zones has been a problem. Real-time crash prediction helps prevent crashes before they happen. This paper looks at real-time crash prediction in freeway work zones by … [Read more...] about Crash Prediction for Freeway Work Zones in Real Time: A Comparison Between Convolutional Neural Network and Binary Logistic Regression Model

Machine Learning Approach to Forecast Work Zone Mobility Using Probe Vehicle Data

The aim of deploying intelligent transportation systems (ITS) is often to help engineers and operators identify traffic congestion. The future of ITS-based traffic management is the prediction of … [Read more...] about Machine Learning Approach to Forecast Work Zone Mobility Using Probe Vehicle Data
