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
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
