Summary
This study addresses the need for the Vermont Agency of Transportation (VTrans) to understand public perception of pavement conditions to better guide investment, timing, and location decisions for roadway paving projects. The research aimed to gather real-time feedback from the traveling public on performance measures and targets, specifically comparing driver perceptions with VTrans’ engineering-based condition ratings. The study was motivated by the desire to reduce recall error associated with traditional survey methods and to determine if VTrans’ current performance targets align with customer expectations. The methodology involved a proprietary smartphone application called "rPlace," programmed for iOS and Android devices, which passively tracked driving trips using GPS and other sensors. Participants were recruited via in-person intercepts at six Vermont Department of Motor Vehicles offices, resulting in 267 active participants who completed 799 post-trip surveys over a two-week period in September 2017. The study covered road segments across all 14 Vermont counties, focusing on state roads classified as Tier 1 through Tier 4. Respondents rated the condition and acceptability of specific road segments immediately after driving them, allowing for direct comparison with VTrans’ database classifications. Key findings indicate that respondents generally held positive views of Vermont’s roads, with approximately 70% rating segments as at least "acceptable" and only 10% as "unacceptable." A significant mismatch exists between public perception and agency classification: 80% of segments VTrans classified as "very poor" were rated as "good" or "fair" by drivers. Demographic analysis showed that older respondents, infrequent drivers, and those driving cars or SUVs provided higher acceptability ratings. Regarding repair urgency, 23% of respondents who rated segments as "poor" or "very poor" demanded immediate repair, while 60% expected repairs within one to two years. Furthermore, the majority of respondents believed VTrans should target no more than 5% to 15% of roads in "very poor" condition, a stricter standard than VTrans’ current 25% target. However, because respondents rated only 3% of segments as "very poor," VTrans is currently exceeding these customer expectations. Engineering indices used by VTrans were found to correlate with respondent acceptability ratings. The significance of this study lies in its demonstration that VTrans’ current management standards likely meet or exceed driver expectations for pavement quality, despite the discrepancy in terminology. The research highlights the effectiveness of real-time mobile data collection in capturing accurate public feedback, potentially serving as a model for other states. The findings suggest that while VTrans’ engineering metrics are valid, communication regarding condition classifications may need adjustment to align with public understanding, ensuring that performance targets remain responsive to customer service standards.
Key finding
Drivers rated only 3% of road segments as very poor, significantly lower than the 15% classified by the agency, indicating a mismatch in perception standards.
