Traffic Operations

TTI has developed an augmented-reality environment where real entities (vehicles and traffic signal operation) are combined with simulated traffic and displayed on a screen. The first-of-its-kind approach — called CONnected Vehicle Assessment Simulation (CONVAS) — marries the cost-effectiveness of computer simulation with actual roadway operations to produce an efficient yet dependable evaluation mechanism for the […]

TTI is deploying CV technology along the I-35 corridor to improve safety and mobility through work zones by providing in-vehicle devices to freight companies to receive work zone infrastructure data on lane closure location, capacity reduction, queue lengths and delay to assist in pre-trip and en-route planning for logistics.

The operation of a mobile retroreflectometer is significantly more complicated than the operation of a portable retroreflectometer. There are many different factors — such as mechanical equipment, operator, and software — that can affect the accuracy of mobile retroreflectivity measurements. Furthermore, it can be challenging to assess the accuracy of mobile measurements. To increase confidence […]

The National Geotechnical Experimentation Site on Texas A&M University’s RELLIS Campus is available for large-scale experiments. At these unique sites, full-scale walls, shallow and deep foundations, culverts, anchors, pipes, and other structures have been instrumented, calibrated, built, and monitored over a period of 20 years.

More than… 50 years of safety research. 4,000 full-scale crash tests. 40 tons of truck brought to a screeching halt. Research performed at the Texas A&M Transportation Institute’s Proving Ground has saved lives for more than 50 years. The TTI Proving Grounds has long been a place where TTI has conducted world-class research, technology development […]

TTI’s Visibility Research Laboratory, located on the first floor of TTI’s State Headquarters Building, is the first of its kind in a university setting. The lab features a 140-foot-long by 15-foot-wide corridor for testing retroreflective materials as well as coatings, lights and other technologies designed to provide nighttime visibility. The lab also has ventilation systems […]
