Summary
This study evaluated the effectiveness of a behavioral intervention package—consisting of prompts, goal setting, and feedback—on increasing following headway and reducing hard braking among young drivers in a simulated environment. The research was motivated by the safety risks associated with short following headways, particularly when compounded by distractions like cell phone use. While previous literature offered mixed results regarding the impact of cell phones on driving performance, no studies had examined behavioral training procedures to increase following headway. The authors aimed to determine if such an intervention could improve safety metrics and whether cell phone use influenced these outcomes. The study employed a concurrent multiple baseline design across four university students with limited driving experience, using a reversal phase to test maintenance. Participants were selected based on a baseline mean following headway of less than 2 seconds while talking on a cell phone. The setting was a driving simulator where participants followed a lead vehicle at 45 mph. During baseline, participants drove for 10-minute sessions, alternating between 2.5-minute periods of talking on a cell phone and driving without one. The intervention involved prompting drivers to maintain a following headway of 3 seconds or more, providing a specific goal, and delivering vocal feedback on their mean headway at the end of each session. Hard braking was defined as deceleration of 9 ft/s² or more. Results indicated that the intervention significantly increased following headway for all participants to above 3 seconds, regardless of whether they were using a cell phone. Concurrently, mean braking deceleration decreased below the hard braking threshold for most participants during the intervention phase. However, these improvements were not maintained after the withdrawal of the intervention; following headway decreased and hard braking levels returned toward baseline values. Cell phone use did not significantly affect following headway or braking measures at any phase. One participant initially struggled with the cognitive workload of counting headway while conversing, but performance improved with practice, suggesting that initial decrements may be related to task novelty rather than the distraction itself. The findings suggest that prompting, goal setting, and feedback can effectively increase following headway and reduce hard braking in young drivers, potentially lowering crash risk. However, the lack of maintenance after intervention withdrawal highlights the need for strategies that promote long-term behavior change, such as self-monitoring or educational components explaining crash risks. The study also implies that drivers may adapt to cell phone conversations by adjusting their driving behavior, as cell phone use did not negatively impact the measured safety variables. Future research should explore interventions that sustain these improvements and validate simulator results with real-world driving data.
