The Hawaii Department of Transportation (HDOT) is responsible for the planning, design, construction, operation, and maintenance of State facilities for all modes of transportation. HDOT’s mission is to provide a safe, efficient, accessible, and sustainable inter-modal transport system that ensures the mobility of people and goods and enhances and/or preserves economic prosperity and quality of life.
CUSTOMER SINCE
2022
Overview
Back in 2021, HDOT partnered with Deighton to implement a Pavement Management System (PMS) using dTIMS Business Analytics (BA), addressing unique challenges such as tight deadlines, earthquake and lava risk factors, and complex budgeting requirements across functional asset classes. Within six months, Deighton configured the system, completed initial runs, and trained HDOT staff, enabling the agency to generate multi-year, budget-constrained work programs and long-term pavement condition forecasts for both project segments and HPMS tenth-mile segments.
A few years later in 2024, the agency wanted to expand the system to track Hawaii-specific measures in addition to existing FHWA (TAMP reporting) metrics, and to gain a more hands-on understanding of the methodology behind the system. They were looking to load multiple years of historical pavement distress survey data, update pavement metrics, and implement new calculations for these metrics.
Challenge
HDOT also wanted to enhance the PMS with new deterioration curves, update the treatment catalogue including treatment costs and decision trees, and refine their benefit priority model to align with HDOT funding categories.
Solution
Deighton’s implementation team worked closely with HDOT to expand the dTIMS BA PMS while addressing the following areas:
A priority system was implemented that delicately shifted the PMS towards HDOT priorities, while maintaining best practices.
New deterioration curves were developed using a regression technique that incorporated client input, allowing the models to account for potential errors in historical data.
A comprehensive User Acceptance Testing (UAT) process was conducted, with training delivered concurrently and handouts provided to ensure long-term usability.
HDOT’s funding categories were adopted to reflect district funding pools.
“The success of any PMS rests on its ability to provide reliable results to as many stakeholders as possible. With this project, HDOT is in a position to satisfy both FHWA and HDOT executive with the dTIMS PMS. ”
Results
As a result of these updates, HDOT now has a reliable system to forecast both FHWA and Hawaii-specific metrics using the updated deterioration curves. The agency can report federally while also tracking the measures and meeting the goals that matter most to them internally.
By developing deterioration curves quickly through a reusable process and involving the client throughout, the project reinforced a user-centered approach. The updated UAT process, along with hands-on training and lasting materials, ensures HDOT is well-positioned to use dTIMS BA effectively for years to come.
