The American Transportation Research Institute (ATRI) has released the first of two surveys dealing with GPS navigation systems. The survey compiles information gathered by interviewing 677 drivers and 169 motor carriers to gather information about the extent of navigation system use and how these systems are perceived. The second analysis will collect and compare quantitative data on navigation system-generated routes with known truck routes and restrictions.
The popularity of GPS navigation systems has increased dramatically. Global shipments of commercial navigation systems, such as those used in large trucks, will climb from 3 million in 2010 to 7.5 million by 2015. Over the past five years GPS usage has increased dramatically. Nearly all carriers allow their use, while only 1% have a policy prohibiting them.
As these devices become more commonplace the impact on safety is not fully understood. The New York State Department of Transportation (DOT) has stated that 81 percent of bridge strikes were a consequence of large trucks using non-commercial or outdated GPS systems for navigation. FMCSA has begun a campaign to inform drivers of the correct use of GPS devices and will most likely initiate a rulemaking aimed at enrty-level driver training.
A poll of 500 truck drivers in 2012 revealed the following:
- A standard truck road atlas was the most preferred routing option
- Followed by a GPS routing device
- GPS load technology
- Finally, route planning software
As you might expect, age plays a factor in these decisions. Older drivers prefer more traditional methods of route planning while younger and newer drivers easily adopt emerging electronic options.
The majority of drivers have sole responsibility for routing while nearly 1/3rd use routing provided by the carrier. The balance relied on a combination of carrier provided information and self routing. A small number (1%) use other means. The most popular method to obtain routing information was a stand-alone unit such as Rand McNally, Garmin and PC Miler. Other methods used are:
- In-cab systems such as those provided by Qualcomm, PC Miler, and PeopleNet
- Hard copy atlases or road maps
- Printed directions such as those from web-based applications (Google Maps or MapQuest)
- Directions from a dispatcher

Top 5 pluses:
- The navigation system helps with scheduling by keeping track of miles traveled and remaining
- The navigation system is less distracting than other methods of receiving directions
- Verbal directions are provided in real time
- The navigation system automatically re-routes when the driver makes an unplanned turn
- The navigation system automatically re-routes when the driver makes an unplanned stop

Top 5 problems:
- The navigation system was dated (i.e.-did not know changes due to road improvements)
- The navigation system route was incorrect or unsafe for trucks
- The navigation system could not find the destination
- The navigation system took a longer route and interfered with scheduling
- The verbal commands were hard to hear or annoying
