Simulation Study of Freeway Work Zone Scenes for Autonomous Driving Using Simulink and PreScan

To solve the problem of high traffic accident rates in freeway work zones, an in-depth analysis of freeway work zone scenes under an autonomous driving environment was conducted, and traffic conflicts … [Read more...] about Simulation Study of Freeway Work Zone Scenes for Autonomous Driving Using Simulink and PreScan

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

Estimating Safety Benefit of In-Vehicle Work Zone Safety Technology Alerts: A Counterfactual Monte-Carlo Simulation Approach

Work Zone Safety Technologies (WSTs) have exhibited great potential to improve road work zone safety by detecting safety risks and providing warnings to drivers and workers involved. Yet, it remains … [Read more...] about Estimating Safety Benefit of In-Vehicle Work Zone Safety Technology Alerts: A Counterfactual Monte-Carlo Simulation Approach

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

Evaluation of the Causes of Traffic Delays From the Road User’s Perspective Using Statistical Analysis

Traffic delay might be the output of a thriving economy where people and goods are traveling throughout the region at certain times during the day. However, it has a negative impact such as contribute … [Read more...] about Evaluation of the Causes of Traffic Delays From the Road User’s Perspective Using Statistical Analysis

Examining Driving Stability and Traffic Capacity: A Simulation Study on Appropriate Speed Limits in Expressway Work Zones

In order to obtain proper speed limits in expressway work zones, CarSim and TruckSim software were used to determine the critical car and truck safe speeds and then VISSIM software was used to … [Read more...] about Examining Driving Stability and Traffic Capacity: A Simulation Study on Appropriate Speed Limits in Expressway Work Zones
