Impact of Road Sign on Traffic Congestion During Road Repair: A Cellular Automaton Model Study

This study investigates the impact of road signs on traffic congestion during road repairs using a cellular automaton (CA) model. The model simulates an urban dual-lane one-way road, incorporating a … [Read more...] about Impact of Road Sign on Traffic Congestion During Road Repair: A Cellular Automaton Model Study

Impact of Road Work Zones on Traffic Flow and Safety: A VISSIM-Based Analysis of Driving Behavior and Risk Factors

To achieve Vision Zero and eliminate all fatalities and severe injuries in road traffic, it is necessary to improve road safety for both road users and road workers. Accidents and incidents that occur … [Read more...] about Impact of Road Work Zones on Traffic Flow and Safety: A VISSIM-Based Analysis of Driving Behavior and Risk Factors

Safety and Mobility Impacts of Work Zone Lane and Shoulder Widths

The goal of this research was to quantify the mobility and safety impacts of different combinations of lane width and shy distance to the barrier for a given paved width in work zones. The research … [Read more...] about Safety and Mobility Impacts of Work Zone Lane and Shoulder Widths

From Chaos to Order: Evaluating Behavior-Driven Road Sign Strategies in Work Zone Management

Road construction significantly impacts traffic dynamics, often causing severe congestion, reduced speeds, and elevated accident risks due to lane closures and merging bottlenecks. This study employs … [Read more...] about From Chaos to Order: Evaluating Behavior-Driven Road Sign Strategies in Work Zone Management

Modeling and Simulation of Mixed Traffic Flow in Maintenance Operation Zone Considering the Impact of Trucks in an Intelligent Connected Environment

With the rapid development of intelligent connected technologies, the introduction of connected and autonomous vehicles (CAVs) into mixed traffic flows of passenger and freight vehicles complicates … [Read more...] about Modeling and Simulation of Mixed Traffic Flow in Maintenance Operation Zone Considering the Impact of Trucks in an Intelligent Connected Environment

Forecasting Traffic Flow by Vehicle Category on a Major Highway Impacted by Road Maintenance Works

In this paper the authors look at the forecasting of traffic flow on a major highway in the Netherlands impacted by road maintenance works, examining the effects of lane closures on intensities per … [Read more...] about Forecasting Traffic Flow by Vehicle Category on a Major Highway Impacted by Road Maintenance Works
