Evaluation of Mobility Impact on Urban Work Zones Using Statistical Models
This work correlated the detailed work zone location and time data from the WisLCS system with the five-min inductive loop detector data. One-sample percentile value test and two-sample … [Read more...] about Evaluation of Mobility Impact on Urban Work Zones Using Statistical Models
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
