The State of the Work Zone ITS Industry – 2018

We just enjoyed the 4th of July holiday. As we sat on the deck consuming bar-b-que and adult beverages we considered the state of the work zone ITS industry. We really have come a long way in the past year and that deserves recognition and a quick look back.

One of the most important and most overlooked recent changes is the blurring of the lines between the permanent ITS infrastructure world and the work zone ITS world. At last month’s ITS America show in Detroit, HERE demonstrated their new ability to incorporate live data feeds from work zones along with their partners including software provider GEWI and work zone ITS supplier iCone.

Waze is also incorporating real-time work zone data feeds in their traffic reporting. Both traffic data providers understand the importance of immediate and accurate work zone reporting and are working internally to make better use of our data.

This blurring is going the other direction as well, as Work Area Protection (formerly ASTI Transportation) now offers the option of including Iteris probe data in work zone travel and delay time calculations.

This blurring of the lines may be more important than we realize. Because it becomes less about us versus them for funding and more about an ITS system that works all of the time – especially in work zones. Work zones have always been an afterthought with ITS practitioners. But that is changing. They now understand that the single largest cause of nonrecurring congestion is work zones. And they are working to address that with their permanent systems.

In a recent article in Better Roads Magazine Frank Zucco of Wanco explained that work zone ITS is now much less expensive. Large, elaborate systems are still available and make sense for multi-year projects with major traffic impacts. But more and more simple systems are now being used for queue detection, trucks entering and dynamic merge applications. And, as Frank points out, those are now very dependable and inexpensive, making them a cost-effective solution for most projects.

Research now validates what we all knew intuitively. Queue detection, in particular, has shown major benefits according to the Texas Transportation Institute and AASHTO. We touched on this milestone two years ago in our post “The State of the Work Zone ITS Industry” published on 4/28/16.

And, lastly, work zone ITS helps facilitate the proliferation of automated and autonomous vehicles. Without real time reporting of work zones, AVs are left to navigate them on their own. And the AV world now understands that. We have become a part of the conversation. At the Automated Vehicle Symposium later this month in San Francisco sessions about work zones will be included for the third year in a row. See #33: “OEM/DOT Dialog on Dedicated Lanes, Work Zones and Shared Data” on July 11th. Autonomous vehicles are a big story that will only get bigger. Funding and research will flow to our industry as a result of these conversations.

As an industry, we aren’t yet to the point where our systems are used everywhere they could help. But we can finally see that light at the end of the tunnel.
