The California Department of Transportation (Caltrans) wanted to implement a visualization tool within its deployment of AgileAssets Pavement Analyst, an advanced pavement management system (PMS) known internally at Caltrans as PaveM. The value of the visualization tool would be to facilitate the pavement project review process.
A typical PMS provides a tabular list of recommended projects, without displaying the relationships between the recommended projects and the currently programmed, under-construction, and as-built projects. A visualization tool would enable engineers to clearly identify these relationships, including gaps and overlaps, and to adjust projects effectively before committing funds to them.
Caltrans’ goals were to develop the tool, integrate it with its existing PMS, and use the integrated system to accelerate and improve project selection through advanced data analysis and visualization.
In partnership with the University of California Pavement Research Center (UCPRC), Caltrans moved to develop an automated visualization tool called H-Chart, short for Highway Chart.
