Traffic Operations

Connected Vehicle Assessment Simulation Test Bed

A TTI researcher demonstrates a connected vehicle test application.

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 […]

Connected Work Zone

Semi-truck passing by bluetooth sensor on I-35

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.

Mobile Retroreflectometer Certification Course

Testing track at TTI's RELLIS Campus.

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 […]

National Geotechnical Experimentation Site

The National Geotechnical Experimentation Site on Texas A&M University's RELLIS Campus.

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.

Proving Grounds Research Facility

Crash test at TTI's Proving Grounds

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 […]

Smart Intersection

Smart intersection test facility at the RELLIS Campus

A state-of-the-art traffic signal has been installed at the Texas A&M University System RELLIS Campus. The Smart Intersection further advances research in traffic signal control, detection technology, and connected vehicle infrastructure. This Smart Intersection was developed with contributions from Econolite, the Texas Department of Transportation (TxDOT), and the Texas A&M Transportation Institute (TTI).  Econolite donated […]

Visibility Research Laboratory

Roadway sign reflecting light at night with car approaching.

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 […]
