Official title
Effects of Experience on the Driving Performance of Novice Teen Drivers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will evaluate the driving performance of new teenage drivers and determine to what extent independent driving experience improves driving performance of young drivers. Motor vehicle crash rates are highest among new teen drivers, especially during the first 6 months and 1,000 miles of independent licensed driving. Crash rates decline with experience, and this study will assess the effect of driving experience on performance. Newly licensed teenagers ranging from 16 years, 3 months to 17 years of age and experienced drivers 30 to 50 years of age may be eligible for this study. Candidates must be able to legally drive in the commonwealth of Virginia and have at least 20/40 correctable vision. Participants complete a questionnaire about their health and driving experience. They are then tested on a driving test track. Teens are tested within 3 weeks of obtaining their driver's license and before they have more than 100 miles of independent driving experience. They are tested a second time 6 to 12 months later and after they have more than 1,000 miles of driving experience. A group of experienced adult drivers are also tested to provide a comparison. The driving test is conducted on a smart road - a controlled, 2.2-mile two-lane research track at the Virginia Tech Transportation Institute. It is designed for safety, with restricted access, nothing for a vehicle to hit, carefully placed guardrails, and other safety features. The research vehicle is equipped with airbags, anti-lock brakes, and other safety equipment. It also has sensors and tiny video cameras to assess the behavior of the vehicle and the driver; this equipment does not interfere with the operation of the vehicle. An experimenter accompanies the driver and instructs him or her to perform routine driving skills, such as stopping, changing lanes and maintaining speed, as well as to other tasks such as inserting a CD into an entertainment console, having a conversation, and answering a cellular telephone call. The driver has an opportunity to practice the tasks before being tested. The driver's speed is limited to 35 mph or less during the experiment and the driver is required to wear seat belts and follow safe driving procedures. The experimenter is in the front passenger seat can stop the vehicle using a separate brake pedal.
