Project Overview
For the past several years, our team has been pivotal in transforming the way road condition data is collected and analyzed for the Delaware Department of Transportation (DelDOT). Since 2021, our project scope has encompassed an annual collection of data across 6,000 lane miles, comprising 4,500 miles of state-maintained roads and 1,500 miles of suburban streets. Utilizing the advanced IrisPRO Pave data collection system equipped with state-of-the-art technologies like the LCMS-2 2D/3D imaging system and Ladybug 5+ 360° camera, our methods adhere to AASHTO and ASTM standards, ensuring high fidelity and compliance.

Client Background and Challenges
DelDOT previously contended with subpar data quality issues from another vendor, which diverted critical engineering resources towards error correction rather than optimization of pavement management. The primary challenges included inadequate crack detection and inaccurate distress ratings that impeded efficient pavement management and federal reporting.

Our Approach
To address these challenges, we introduced tailored detection settings via our Connect software for each pavement type, enhancing crack detection accuracy significantly over one-size-fits-all approaches. Additionally, our engineers developed an innovative year-to-year comparison process, which automatically identifies and analyzes any deviations in distress data, streamlining quality assurance and boosting client confidence in the data provided.

Solution Details
Our solutions included the deployment of the Inform™ web-based viewing software, which became a crucial tool for DelDOT and our project partner, Kimley-Horn. This platform facilitates an intuitive understanding of road network conditions and fosters collaborative data review, making it an indispensable part of the pavement management ecosystem.

Execution and Overcoming Challenges
The project was executed without significant deviations from the planned scope, timeline, or budget, showcasing our team’s expertise in managing complex data collection initiatives seamlessly and efficiently.

Results and Impact
The enhanced data collection strategy has allowed us to begin annual surveys earlier in the season, and more efficient data processing has resulted in earlier data deliveries. This shift has been greatly appreciated by our partners at Kimley-Horn and DelDOT, who now benefit from accessing high-quality data well ahead of their internal schedules, aiding in timely decision-making and reporting.

Client Feedback
Sarah McDougall of DelDOT has lauded our efforts, noting the exceptional quality and reliability of the data provided. Her feedback underscores the success of our collaborative approach and technological expertise in meeting and exceeding client expectations.

Key Takeaways
Overall, this case study exemplifies our dedication to innovation and client satisfaction, ensuring that every mile of pavement managed is a testament to our advanced capabilities and client-focused approach.
