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, measuring 15 feet by 125 feet, is the first of its kind in a university setting. Located on the first floor of TTI’s State Headquarters and Research Building, the laboratory can be used to perform photometric and color measurements of sign sheeting, pavement markings, retroreflective raised pavement markings and other retroreflective […]
