The Challenge
TxDOT has deployed a system to alert truck drivers when they exceed the safe, posted speed limit on freeway ramps. The goal is to reduce the number of semi-truck rollovers that occur when truck drivers attempt to negotiate the ramps at unsafe speeds. Magdy Kozman, transportation operations engineer at TxDOT, says there was considerable trouble on tight interchange connector ramps around Houston. “There were high instances of trucks rolling over due to excessive speed, unknown cargo loading factors, and freeway super elevation problems,” Kozman says. TxDOT needed a non-intrusive solution because their previous loop system required a traffic control plan to close the ramp for installation. It also needed to get creative with methods of alerting drivers. “The flashing system was a challenge because no other similar application existed to our knowledge,” Kozman says.

The Solution
The system TxDOT has implemented relies on the highly accurate per vehicle speeds provided by SmartSensor HD’s unique, dual-beam radar. HD identifies a vehicle’s speed and length and activates a flashing warning sign, as well as an LED speed sign, if the vehicle meets a predefined length and is traveling faster than a predefined speed limit. The goal is to reduce truck rollovers by warning drivers immediately to reduce their speed.
