Crashes continue to be a problem in work zones. Analyses have indicated that rear-end and sideswipe crashes are the most frequent. Investigators have hypothesized that distractions are often the cause … [Read more...] about Driving Simulator Evaluation of Driver Performance During Hands-Free Cell Phone Operation in a Work Zone: Driving Without a Clue.

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
The Use of Operational Models to Evaluate Construction Staging Plans, A Case Study
Construction staging has traditionally been a process of identifying the critical "measured" demand and designing staging plans to ensure that sufficient capacity exists within the construction zone … [Read more...] about The Use of Operational Models to Evaluate Construction Staging Plans, A Case Study
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
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
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”
