Length of Need and Minimum System Length for F-Shape Portable Concrete Barrier
Portable concrete barrier (PCB) systems are often used to redirect errant vehicles through a combination of inertial resistance, lateral friction loads, and tensile loads developed from the mass and … [Read more...] about Length of Need and Minimum System Length for F-Shape Portable Concrete Barrier
Development of a MASH TL-3 Transition Between Guardrail and Portable Concrete Barriers
Often, road construction causes the need to create a work zone. In these scenarios, portable concrete barriers (PCBs) are typically installed to shield workers and equipment from errant vehicles as … [Read more...] about Development of a MASH TL-3 Transition Between Guardrail and Portable Concrete Barriers
MASH Evaluation of TxDOT High-Mounting-Height Temporary Work Zone Sign Support System
The objective of this research was to develop a nonproprietary, lightweight, crashworthy, temporary work-zone single sign support for use with an aluminum sign substrate. The device is intended to … [Read more...] about MASH Evaluation of TxDOT High-Mounting-Height Temporary Work Zone Sign Support System
More Robust DOT Oversight of Guardrails and Other Roadside Hardware Could Further Enhance Safety
In 2014, 54 percent of traffic fatalities in the United States occurred as a result of a vehicle's leaving the roadway, according to U.S. Department of Transportation's (DOT) data. Roadside safety … [Read more...] about More Robust DOT Oversight of Guardrails and Other Roadside Hardware Could Further Enhance Safety
Testing of Alternative Supporting Materials for Portable Roll-Up Signs Used for Maintenance Work Zones
Portable roll-up signs are currently used by the Texas Department of Transportation (TxDOT) for identification of short-term maintenance/work zones and emergency operations. These signs have … [Read more...] about Testing of Alternative Supporting Materials for Portable Roll-Up Signs Used for Maintenance Work Zones
