Using iNode for Work Zone Monitoring

Work Zones Travel Time Monitoring

In today’s world, the majority of infrastructure needs to be updated and maintained regularly. Unfortunately, construction has an effect on the flow of traffic, negatively impacting travelers and the ability of companies to move goods efficiently. With the inevitable negative aspects of construction, it is difficult to make construction plans that don’t create a slow moving work zone and annoyed travelers. On top of minimizing delay, there is also a responsibility for improving driver and worker safety within these zones.

Having accurate and current information on work zone delays and expected wait times is the key to minimizing citizen impact, whether it’s infrastructure creations or improvements. By displaying real time information to travelers so they can effectively plan their routes, the cons of work zones are minimized, making happy municipalities and citizens. Luckily, real time traffic data is exactly what SMATS delivers.

How Does it Work?

With SMATS sensors placed at the beginning and end of construction zones as well as at several midpoints within it and iNode™ data analytics platform, cities and traffic managers are able to measure travel times in construction zones. By knowing the expected delays caused by work zones, this information can be broadcast to travelers so they can plan their trip accordingly, minimizing overall delay. Real-time data collections are used to send out automatic messages to variable message signs (VMS) to possibly divert drivers to alternative routes, resulting in active and autonomous management over the flow of traffic. Additionally, construction managers can use the information to match their service rate to the level of demand, creating safer work zones, and further reducing delay as well as departmental costs for over or understaffing.

“The accuracy and live data availability provided by SMATS sensors were exactly what we needed. They delivered the tools and support we needed to create an efficient, accurate ITS for our work zone.”

Sensor Installation & Power Source


TrafficXHub can be installed on existing poles and infrastructures and powered by solar panels and batteries (SMATS provides the solar unit). 

Trailer Mounting:

The sensor can be installed on a trailer and connected to the trailer’s solar unit. 



TrafficXHub is equipped with an onboard LTE modem compatible with carriers around the world. 

Trailer Model: 

TrafficXHub can connect with the trailer’s exiting modem through the sensors’ Ethernet port. 


Integration with Work Zone Management Applications

The iNode application can share the travel time data on the configured links and routes through the RESTful API.

The API documentation is available for the partners.
