Simulation-Based Estimates of Delays at Freeway Work Zones
Work zone related traffic delay is an important cost component on freeways with maintenance activities. This study demonstrates that delays are always underestimated by using the deterministic queuing … [Read more...] about Simulation-Based Estimates of Delays at Freeway Work Zones
Development of a Low Profile Work Zone Barrier Using Impact Finite Element Simulation
A new low profile portable concrete barrier system developed for use in roadside work zone environments is presented. It is shown that by making extensive use of nonlinear dynamic finite element … [Read more...] about Development of a Low Profile Work Zone Barrier Using Impact Finite Element Simulation
Evaluation of Rural Interstate Work Zone Traffic Management Plans in Iowa Using Simulation
Traffic levels on Interstate Highway 80 in eastern Iowa increased percent between 1988 and 1997, with summer traffic volumes approaching 40,000 vehicles per day. These traffic levels and the expected … [Read more...] about Evaluation of Rural Interstate Work Zone Traffic Management Plans in Iowa Using Simulation
Modeling and Optimization of the Indiana Lane Merge Control System on Approaches to Freeway Work Zones
Severe traffic turbulence on entry sections of freeway work zones increases the delays and risk of crash. A new Indiana Department of Transportation system called Indiana Merge Lane System (IMLS) … [Read more...] about Modeling and Optimization of the Indiana Lane Merge Control System on Approaches to Freeway Work Zones
Driving Simulator Validation for Nighttime Construction Work Zone Devices
Research was conducted to ascertain the validity of a driving simulator in determining the effectiveness of temporary traffic control devices in a work zone during nighttime hours. The research was … [Read more...] about Driving Simulator Validation for Nighttime Construction Work Zone Devices
