The Texas A&M Transportation Institute’s (TTI’s) instrumented vehicles allow researchers to conduct driver behavior research in test track and on-road environments. The vehicles are equipped with vehicle acquisition data systems and other portable systems that allow TTI research staff to evaluate driver response and performance to a variety of on-road devices and in-vehicle technologies.
TTI’s newest instrumented vehicles are a 2015 Toyota Sienna and a 2015 Ford Explorer. A 2006 Toyota Highlander serves as an additional instrumented vehicle. The vehicles can each be used alone or in tandem.
Vehicle Data Acquisition Systems
The principal system used within TTI’s 2015 instrumented vehicles is the Dewetron DEWE2-M4- ADAS vehicle data acquisition integration system. Essentially a large portable computer, the system serves as the data acquisition device for all the peripheral systems in the vehicles. The Dewetron ADAS consists of a 120 GB solid-state disk drive combined with an Intel Core i7 processor running on a standard Microsoft Windows platform. The instrumentation allows eight analog and up to four CANBUS inputs. Also supported are eight digital inputs and eight digital I/Os, with data collection rates up to 5,000 samples per second.
