Determination of Diversion Sensitivity at Urban Freeway Work Zones Using Bluetooth Devices
Planning agencies need to assess the change in travel times and diversion rates attributed to work zones to reduce the adverse effect on mobility of the roadways. To assess such changes, … [Read more...] about Determination of Diversion Sensitivity at Urban Freeway Work Zones Using Bluetooth Devices
Multi-Contextual Approach to Modeling Traffic Impact of Urban Highway Work Zones
Impact assessments of highway construction work zones (CWZ) are mandated for all federally-funded highway infrastructure improvement projects. However, most existing approaches are ad-hoc or … [Read more...] about Multi-Contextual Approach to Modeling Traffic Impact of Urban Highway Work Zones
A Guide to Urban Work Zone Temporary Traffic Control
This guide describes the characteristics that are specific to urban work zones and provides possible mitigation strategies to address site-specific safety issues. Urban work zones present unique … [Read more...] about A Guide to Urban Work Zone Temporary Traffic Control
Delay and User Cost Estimation for Work Zones on Urban Arterials
This is the final project report of NCDOT research project 2013-09: Delay and User Cost Estimation for Work Zones on Urban Arterials. The project seeked to develop a methodology for quantifying delay … [Read more...] about Delay and User Cost Estimation for Work Zones on Urban Arterials
Traffic Flow Forecasting for Urban Work Zones
None of numerous existing traffic flow forecasting models focus on work zones. Work zone events create conditions that are different from both normal operating conditions and incident conditions. In … [Read more...] about Traffic Flow Forecasting for Urban Work Zones
