Dynamic Modeling of Wheeled Mobile Robots for High Load Applications
This paper examines dynamic modeling of differentially and conventionally steered Wheeled Mobile Robots (WMRs) for high load applications such as highway maintenance and construction. Dynamic models … [Read more...] about Dynamic Modeling of Wheeled Mobile Robots for High Load Applications
Work Zone Simulation Model: Companion Report for “Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones”
To support the analysis of driver behavior at rural freeway work zone lane closure merge points, CTRE staff collected traffic data at merge areas using video image processing technologies. The … [Read more...] about Work Zone Simulation Model: Companion Report for “Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones”
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
