A Computational Vision Model-based Method to Address Work Zone Conspicuity
A computational means to assess the conspicuity of highway features was developed, verified, then applied to a sample construction work zone scene. This work was conceived as a balance between … [Read more...] about A Computational Vision Model-based Method to Address Work Zone Conspicuity
Crash Testing and Analysis of Work Zone Sign Supports
A wide variety of traffic controlling devices are used in work zones, some of which are not normally found on the roadside nor in the traveled way outside of the work zones. These devices are used to … [Read more...] about Crash Testing and Analysis of Work Zone Sign Supports
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
Distribution and Characteristics of Crashes at Different Locations Within Work Zones in Virginia
Work zones tend to cause hazardous conditions for vehicle drivers and construction workers since these work zones generate conflicts between construction activities and the traffic, and therefore … [Read more...] about Distribution and Characteristics of Crashes at Different Locations Within Work Zones in Virginia
Effect of Speed Monitoring Displays on Entry Ramp Speeds at Rural Freeway Interchanges
The effectiveness of speed monitoring displays (SMDs) in controlling the speed of on-ramp traffic at rural freeway interchanges was evaluated as part of the Midwest States Smart Work Zone Deployment … [Read more...] about Effect of Speed Monitoring Displays on Entry Ramp Speeds at Rural Freeway Interchanges
