A Computational Vision Model-based Method to Address Work Zone Conspicuity
A computational means to assess the conspicuity of highway features was developed, verified, then applied to a sample construction work zone scene. This work was conceived as a balance between … [Read more...] about A Computational Vision Model-based Method to Address Work Zone Conspicuity
Feasibility of Real-Time Remote Speed Enforcement for Work Zones
Studies have shown that a large percentage of vehicles involved in work zone crashes are traveling at excessive speeds. While traditional speed enforcement has been shown to reduce speeds through the … [Read more...] about Feasibility of Real-Time Remote Speed Enforcement for Work Zones
Guidelines for Estimating Freeway Capacity at Long-Term Reconstruction Zones
This paper reports findings from recent investigations into freeway capacity at several long-term reconstruction zones in Ontario, Canada. The aim is to provide guidelines for estimating freeway … [Read more...] about Guidelines for Estimating Freeway Capacity at Long-Term Reconstruction Zones
A Methodology for Assessing the Impact of Radar Transmissions on a Work Zone
A new method of speed reduction in work zones is being investigated where an informational safety message is sent to drivers equipped with compatible receivers. The Safety Warning System, a currently … [Read more...] about A Methodology for Assessing the Impact of Radar Transmissions on a Work Zone
Evaluation of Speed Reduction Techniques at Work Zones
The goal of the Midwest States Smart Work Zone Deployment Initiative (MwSWZDI) is to develop better ways of controlling traffic through work zones, which improves traffic safety and traffic operating … [Read more...] about Evaluation of Speed Reduction Techniques at Work Zones
