Self-monitoring of driving speed

Area of Science:

• Traffic Safety
• Human-Computer Interaction
• Behavioral Economics

Background:

• In-vehicle data recorders (IVDRs) enhance driving safety and accident analysis but face driver privacy concerns.
• Adding a turn-off switch to IVDRs addresses privacy but may increase speed variability, potentially reducing safety.

Purpose of the Study:

• To investigate the impact of IVDRs with a turn-off option on driving behavior under different fine structures.
• To determine if a turn-off switch negates the safety benefits of IVDRs, particularly concerning speed variability.

Main Methods:

• A computerized speeding dilemma task involving 199 students simulating driving behavior.
• Two experimental conditions with IVDRs: one with small fines for speeding, the other with large fines.
• Participants could activate or deactivate the IVDR, with active use incurring a probability of fines.

Main Results:

• The option to use IVDRs significantly reduced both speeding and speed variance.
• The reduction in speed variability was most pronounced in the group subjected to small fines.
• No increase in speed variance was observed when IVDRs were used with a turn-off option and gentle fines.

Conclusions:

• IVDRs with a turn-off option can mitigate privacy concerns ('Big Brother' effect) while maintaining safety benefits.
• Gentle fines, in conjunction with a turn-off option, optimize IVDR effectiveness by reducing speed variance.
• This approach balances driver privacy with enhanced road safety, making IVDRs more acceptable to drivers.
