Highlights
- Chronoceptive ramp metering designs significantly improve user acceptance and perceived fairness compared with standard ramp metering, despite providing the same underlying traffic-control benefits.
- Shorter signal cycles, countdown timers, and three-phase signals reduce perceived waiting times and increase preference for ramp metering, with the 45 s cycle design achieving the highest acceptance rates.
- Intelligent transportation systems should be designed not only for objective efficiency but also for users’ subjective perception of time, as perceived benefits strongly influence acceptance and compliance.
- Chronoceptive design offers a practical human-centred framework for reducing public resistance to traffic-control measures and improving the real-world effectiveness of ITS deployment
Abstract
Intelligent transportation systems (ITSs) and traffic control promise substantial efficiency and safety improvements but frequently face public resistance and driver compliance issues. Many drivers perceive such control measures as unfair or unnecessary, despite measurable system-wide benefits. This study investigates how chronoception—the subjective perception of time—affects user acceptance of ITS control strategies and how signal design can be adapted to reduce perceived delays. We introduce a chronoceptive design framework that integrates insights from cognitive psychology into traffic-control design. Using ramp metering as a case study, we conduct virtual experience stated preference experiments with 101 participants, comparing standard and chronoceptive ramp metering designs featuring shorter signal cycles, three-phase lights, and countdown timers. The results show that chronoceptive signal designs significantly improve user acceptance (by up to 12%) and reduce perceived waiting times, despite identical or slightly longer objective travel times. These findings reveal a systematic bias between factual and perceived benefits and highlight the potential of chronoceptive design to enhance compliance and fairness perception. This study contributes a new human-centred design paradigm for traffic control that aligns objective performance with user perception and outlines how chronoception and perceived fairness can be operationalised in traffic control.
