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
Traffic Incident Management on Rural Roads
This program applies traffic incident management (TIM) principles directly to the rural roads context using a two lane road as the example. The program highlights how fundamental TIM principles can be … [Read more...] about Traffic Incident Management on Rural Roads
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
Model Development for Use of Portable Traffic Signals in Conjunction with Pilot Car Operations at Two-Lane, Two-Way Rural Highway Work Zones
A portable traffic signal (PTS) system is a traffic control device designed to facilitate the movement of one-way traffic at work zones where there is a temporary lane closure. The 2009 edition of the … [Read more...] about Model Development for Use of Portable Traffic Signals in Conjunction with Pilot Car Operations at Two-Lane, Two-Way Rural Highway Work Zones
