“This is the first study to use vehicle and roadway GPS and video technology on farm vehicles to develop a safety campaign to improve rural roadway driving behavior at the community-level.” – PI Cara Hamann
Why is this research important?
Farm equipment crashes, which often involve a vehicle rear-ending or passing the farm equipment, are frequent causes of injury.
Occupants in the non-farm vehicle are the most likely to be injured in these frequently severe crashes.
In order to better understand risk factors for rural roadway crashes–especially those involving farm equipment–we have developed a video/GPS system to record vehicle interactions with farm equipment.

What is SaferTrek?
SaferTrek is a rear-facing GPS data acquisition system designed to capture the frequency and types of driving behaviors of rear-approaching vehicles. We are examining behaviors such as speed, deceleration while approaching farm equipment, following distance, number of passing attempts, and passing.
What are we doing now?
- Phase 1: We are using our SaferTrek data collection system to objectively observe vehicles as they approach farm equipment. The aims are to a) measure farm equipment exposure to the roadyway (miles traveled, location) and the frequency with which cars approach the farm equipment; and b) identify behavior of vehicle drivers as they approach farm equipment from behind.
- Phase 2: We are currently developing a community-level safety campaign that emphasizes increased driver awareness and error reduction when sharing the road with farm equipment. Once development is complete we will implement and evalutate the campaign. The aims in this phase are to a) estimate the effectiveness of a community campaign by measuring change in attitude and perceptions of threat, efficacy, and norms about safe driving around farm equipment via surveys and interviews; and b) measure efectiveness of a community campaign to improve driver behavior when approaching farm equipment on the roadway, using objective data from SaferTrek. The community intervention will use a two-community design with one intervention and one control community. The intervention will deliver tailored messages through local small media (e.g., newspapers, businesses, and farm operators).
Over the next year we will continue to collect roadway data of farm vehicle and passenger car interactions. We will also finish development of our community campaign and implement it into our intervention community. Following campaign implementation, we will collect additional data to evaluate its effectiveness on driving behavior, attitudes, and perceptions.
