Abstract:UDOT is developing a dashboard that can display information for winter storm events. This project is focused on creating a one-stop shop for decision-making tools and will serve to inform operations managers, who will be making decisions based on feedback from the dashboards. The recommendations this report makes will help the Maintenance Operations management team understand their options for snowplow data management. Literature support and data collection methods had already been established in previous efforts, so this project focused on extending current knowledge into better and more integrated analysis tools. Challenges remain for parsing large-scale data, such as big data collection issues and platform instability. Currently, the snowplow dashboard offers a simple view of the cost of operations. Other tools (such as letter grade, duration, and maximum intensity) will be integrated when the platform is adequately stable and as other data enhancements are made. One of the biggest challenges UDOT is facing is the large volume of snowplow locations, which makes it difficult to prepare and visually display all the data points. The ArcGIS GeoEvent Server being used for the dashboard crashes often, and the entire workflow is complex and somewhat fragile. The web map also becomes slow and cluttered if it tries to display all the snowplow locations for a given snowstorm, which detracts from the user’s experience and ability to use the dashboard. Before the dashboard can be fully implemented, these challenges will need to be addressed. UDOT is currently investigating a possible alternative for processing the location points in a way that will avoid the current technical challenges, at least until a stable installation is achieved.
