Data can be collected using printed forms or on-board data logging equipment. We are experienced with numerous different data loggers and can recommend systems for your applications.


The ATDS Advantage

Low Cost

Durability programs have many hidden costs —

Driver recruitment, training, scheduling and daily management add cost to your programs and require specific experience in each location. By choosing ATDS, you only pay for what you need — without long term fixed costs, capital investments or additional personnel.

Flexibility and Location

We believe in going where you need us the most. ATDS routinely operates in locations around the United States and Canada to test vehicles under all extreme environmental conditions. If you have a unique environmental or demographic requirement, we can select and begin operation in a new location within three weeks.

Risk Management

Driving millions of miles on public roads annually involves risk of accident. We maintain multi-million USD liability insurance coverage and are experienced in minimizing accidents while maximizing safety. Fewer accidents mean less delay and lower costs for your program.


We can provide the exact driving environment needed to collect the data you require: urban, freeway, off-road, mountain, desert, cold or hot and humid. In our seasonal facilities, we can provide cold start drivability after an overnight soak at -40°F in Alaska. We can also test fuel system drivability after an extended idle and hot soak at 125°F in Death Valley, CA.
