Driving Forward with VDOT’s Integrated Directional Signing Program

While driving on the highway you likely find yourself looking at signs lining the road to determine your next meal, gas stop, or a place to stay. You probably do not consider that there is a directional signing program that manages the accuracy of these signs, but you trust the information and services they provide. 

In Virginia, Blue Raster partnered with Directional Signing Program (DSP) to put in place Esri workflows that help ensure you can trust these signs. Using ArcGIS Online, Field Maps, Survey123, Workforce, and Dashboards, the signing program at VDOT has never been more interactive and in real-time. The Integrated Directional Signing Program (IDSP) includes over 16,000 signs across the State and is comprised of:

  • Logo Guide Signs - Blue highway signs with gas, food and lodging company logos
  • Tourist-Oriented Directional Signs - Blue highways signs with directional information, no company logos
  • Supplemental Guide Signs - Cultural, recreational, education and historic guide signs
  • General Motorist Service Signs - Generic symbols representing Gas, Food, Lodging, Hospitals and Camping
  • Historic Markers - Signs depicting historic information about places, people or events

Blue Raster's workflows for field GIS allow DSP and other VDOT contractors to inventory and update the status of every sign in the IDSP. The initial inventory of all 16,000 signs was completed in just 5 weeks with the help of Field Maps and offline capabilities. Since then, routine inspections for condition and retroreflectivity, construction inspections, or maintenance work orders for signs has been managed in GIS with Esri's field applications. Data from the field crews feed a series of dashboards configured to show key metrics and status to VDOT in real-time.

Beyond just VDOT, the IDSP is made up of the customers on the signs and the public. Through hosted web maps and Survey123 forms, there is now the ability for both customers and the public to view an interactive map of all the signs in the IDSP (with current image), provide general feedback on the program, and report sign issues or knockdowns.

Integrating ArcGIS into the IDSP allows for significant improvements to data collection, understanding of assets, efficiency, reporting and tracking goals. Continued work with DSP and VDOT includes developing StoryMaps around the Historic Marker Program, leveraging Business Analyst to attract new customers and understand interchange saturation and vacancies, and better use of imagery including 360 degree capture. All of this work makes the IDSP better, and provides a better experience to drivers in Virginia.

Mekong Monitor – Providing Vital Insight for River-dependent Communities

The Mekong River runs through six countries: China, Myanmar, Laos, Thailand, and Cambodia, and Vietnam. It provides a livelihood and natural resources for over 60 million people. New upstream dams in China are changing the waterflow, creating a huge impact on the countries and people that depend on the river. Using the Mekong Dam Monitor as a tool, the Stimson Center’s Southeast Asia Program and Eyes on Earth, Inc committed to working with countries to gain more visibility into the flow of the river and better plan for water availability.

Mekong MonitorBlue Raster developed the Mekong Dam Monitor to provide unprecedented transparency of the flow of water and conditions of dams and reservoirs along the Mekong River. Using satellite data as well as weather and water gauge data, the monitor provides visibility into what is happening upstream, giving a comprehensive near-real time view of the current state of the Mekong basin along with historic conditions. This allows people all along the river and those advocating for more equitable and sustainable use of the river to understand and plan for changes in the levels of the river.

Mekong Monitor

In late 2021, Blue Raster integrated WordPress into the application, making it easier for the project administrators to make updates to the site themselves. The site also received an update to the UI, making it more mobile friendly to support growing field use. Finally, the team also coordinated making the site available in six local languages, increasing the access to this valuable data on water levels and projected water flow.

Blue Raster is proud to continue to support this project, providing real time visibility and reporting on impacts of up river decisions on the various communities that rely on the Mekong.
