During the 2019 NADO Annual Training Conference (October 19 - 22 in Reno, NV), Seth Daniels shared the Nevada Department of Transportation's efforts to upgrade communications to meet current and future intelligent transportation systems needs.

NDOT has chosen to deploy what we call an “enterprise-class” roadside network to meet these challenges. This “enterprise-class” network inherits many of the standard features found in an IT network. First of all, it’s fully managed centrally from our operations center. We can see every switch, every port and perform diagnostic tests with a few clicks rather than a truck roll. In the event of an issue we can quickly figure out what’s gone wrong and perform the appropriate action and get the service back on line ASAP. We have adopted the idea of reducing service outage time, and reducing Mean Time to Recovery. This enterprise-class network also includes tools built into the management platform that allow us to see usage trends throughout the network so we can make adjustments or plan for enhancements well before they become an issue. What’s especially useful is the ability to leverage predictive analytics so we can project network usage 6 months or a year from now. It goes without saying that any network you deploy must be based on open standards so that you have the flexibility of choosing different vendors to meet your needs. One standard NDOT is particularly happy about is Shortest Path Bridging, which we use all the way to our cabinets. SPB allows us to get rid of the convergence issues that are typical of legacy networks that are based on spanning tree. We’ve completely eliminated spanning tree from our network, and the reliability of the network has improved significantly as a result.
During the 2017 Legislative Session, the passage of SB53 provided NDOT with greater latitude in regard to entering into public/private partnerships involving telecommunication transport facilities. We feel that it will ultimately allow us to expand our reach for the purpose of providing public service, especially in regard to rural areas and associated public facilities such as schools and hospitals, while reducing costs to the taxpayer. SB53 has been modeled after the very successful program currently deployed in the state of Utah. SB53 enables NDOT to enter into agreements with the private telecom industry, and grant access to our utility-designated conduits and related facilities, in return for reciprocal compensation from the provider. This will provide attractive options from an expense perspective to both the State and those partner-providers, through a mutually beneficial agreement.
MY511NV allows users to create a profile allowing them to quickly access their favorite cameras and route information as well as to set up personalized automated alerts via text and/or email.
Waycare provides a cross-jurisdictional browser based interface that NDOT ROC/FSP, RTC-FAST, and NHP personnel are collaboratively using to improve incident detection and response performance. The system integrates publicly available datasets to provide predictive insights and more connectivity amongst first responders so that proactive measures can be taken to mitigate the emergency situation.
TIM consists of a planned and coordinated multi-disciplinary process to detect, respond to, and clear traffic incidents so that traffic flow may be restored as safely and quickly as possible.

ITS NETWORK UPGRADE
Roadside Networks need to evolve and become “enterprise-class”
Better management tools to facilitate
troubleshooting, decrease MTTR
Analytics to better understand usage
Open, standards-based protocols
like shortest-path bridging…
… allows for the elimination of spanning
tree, increasing reliability
