Portland State University
Portland State University set out to examine how Covid-19 regulatory relaxations affected heavy vehicle driver behaviour, focusing on Electronic Logging Device (ELD) compliance and parking patterns. The goal was to quantify the behavioural impacts of the relaxations, providing evidence for evaluating future policy adjustments that balance safety with operational flexibility.
Approach
- Trip Analysis – Analysed GPS data for all trips entering or leaving Oregon, identifying stop locations and classifying them as inside or outside carrier facilities.
- ELD Break Behaviour Assessment – Measured driving time before mandated ELD breaks for both pre-Covid and post-Covid periods to detect behavioural changes.
- Data Integration and Comparative Analysis – Combined parking and ELD timing data into a single framework, enabling direct comparison between the two timeframes.
Key Findings
- Shift in Break Timing – Evidence of changes in the length of drive time before taking an ELD break under relaxed regulations.
- High-Use Parking Locations – Identified parking hotspots outside carrier facilities, providing insight into infrastructure demand.
- Policy-Relevant Behaviour Changes – Highlighted adjustments in compliance patterns that could influence future regulatory frameworks.
Impact
- Support for Policy Evaluation – Equipped Portland State University with empirical evidence to assess the real-world effects of regulatory changes.
- Parking Infrastructure Insight – Provided data on where improvements or additional capacity could alleviate parking shortages.
- Academic Contribution – Findings are being formalised into a research paper, expanding the academic and industry discourse on regulatory flexibility.
