Cobb County DOT’s readiness efforts for winter weather include five staging areas for salt and pre-defined treatment routes, as well as equipment for de-icing and snow removal. However, knowing the challenges associated with a major snow event, Cobb also required a traffic management solution that would help it efficiently plan road maintenance and allocate resources during inclement weather. The organization’s need proved threefold:
The powerful combination of Cartegraph and the ArcGIS platform answered Cobb County’s need. During the snow events of 2014, the County used the systems in perfect tandem. By combining Cartegraph’s road asset management system software with the road segments feature class in the Esri ArcGIS platform and traffic counts event layer, the DOT created an effective and efficient response that:
The Cobb County DOT GIS team has also created a proof-of-concept ArcGIS Dashboard that pulls AVL tracking information in through ArcGIS GeoEvent Server, updating the status of routes that were cleared as tasks are opened and closed in Cartegraph. The map shows the status of the snow route, with the color-changing based on when the surface was last treated.
The winter weather dashboard also includes gadgets with surface temperatures from Georgia DOT, links to live camera feeds of road conditions, and real-time weather reports from Waze.
The Cobb County DOT crew appreciates having their mission-critical data sources in one place. During snow events, they intend to display this ArcGIS Dashboard on the big screen in their ‘war room’, so they can closely monitor the situation.
Meanwhile, residents can access Cobb Commute, a public-facing map with real-time road conditions. This keeps everyone informed and safe.
“This is truly an example of using technology to work smarter,” said Lynn Biggs, Cobb DOT GIS Manager. “Leveraging these technologies helped Cobb DOT streamline our response to winter weather. It’s a game-changer.”
