TxDOT unveils high tech workzone warning system

With more roadway construction underway than ever in the state, the 375 Texas Department of Transportation (TxDOT) is introducing its first highway safety feature that incorporates a queue warning system and temporary rumble strips to reduce work-zone collisions.

Making its debut along a central Texas stretch of I-35, the system uses sensors to measure the speeds of approaching vehicles and then warns drivers through portable, electronic signs about upcoming traffic backups due to night lane closures in work zones. The rumble strips are spaced between sensors to send mild vibrations through oncoming vehicles to get the attention of distracted or drowsy drivers.

“We’re proud to unveil this innovative, new safety technology and are hopeful we can expand the system in other areas of the state,” said Phil Wilson, TxDOT executive director. “This technology represents the future of roadway safety as it uses a comprehensive approach to warn drivers of traffic backups, thereby decreasing the likelihood they will enter a work zone at an unsafe speed. Any technology that has the potential to simultaneously protect motorists and roadside maintenance workers is well worth pursuing.”

    Communications redundancy increases VMS reliability
    Hybrid communications to variable message signs increase resilience to natural disasters and enable deployment in remote areas, as Alan Allegretto explains. Variable Message Signs (VMSs) are a common sight and a well-proven means to improve public safety on our roads and highways. ITS professionals rank the VMS as second only to interoperable radios as the most important technology to improve effectiveness during emergency incidents and evacuations. Ironically, however, current systems suffer from one criti

    Active traffic management - challenges and benefits
    Minnesota DoT has built one of the most intensive Active Traffic Management (ATM) systems on the road today. Like many ITS deployments, the state has gained benefits but also faces many challenges, as Pete Goldin reports. Smart Lanes is the brand name of Minnesota Department of Transportation’s (MnDoT) ATM system on I-35W in the Twin Cities Metro Area. The original system covered 16 miles of I-35W south of Minneapolis starting in 2009, and was extended by two miles in 2011. Additional ATM equipment was inst

    Sign language reduces human error says Clearview
    Wrong-way warning systems and advanced queue detection can help to reduce human error. They can also cut road accidents – and therefore road deaths, says Clearview Intelligence Where were nearly 1,800 deaths on the UK’s roads in 2018 – an average of five people dying each day. The largest single cause of serious injury is crashes at junctions (accounting for 33% of incidents), while the largest single cause of death was run-off road crashes (30%) “With vehicles increasingly being designed with saf

    High-speed WIM moves onto the main highway
    High-speed weigh-in-motion is starting to make its mark on both sides of the Atlantic. As a transit country the Czech Republic experiences a large number of overloaded vehicles, which greatly increase highway maintenance costs. This prompted its Transport Ministry to trial an extension of the capabilities of the existing truck tolling system to allow the dynamic high-speed weighing of cargo vehicles. In effect the tolling enforcement gantries become weigh-in-motion (WIM) locations.
