I-29 SMART Corridor

Crowd-Sourced Information: Through the ND Roads app, NDDOT will collect information to identify and anticipate incidents on North Dakota roads. This approach can reduce the time it takes to identify an incident and dispatch first responders by one third to one half.

Truck Parking Information Management Systems provide real-time parking availability information to drivers. Vehicle detection at rest areas and/or truck stops can be relayed through dynamic message signs, the ND Roads Map, and navigation systems to long-haul drivers.

Variable Speed Limits from south of Fargo across Grand Forks factor in real-time travel speeds, weather, incidents, special events, and work zone information to continuously maintain a safe speed limit. This approach to traffic management has the potential to avoid or lessen the severity of over 135 crashes per year.

Ramp Metering during peak traffic periods is included on I-29 and I-94 in Fargo. By moderating the rate that vehicles enter the interstate system, this system has the rate to reduce 75% of peak hour delays (which is consistent with applications in the Minneapolis-St. Paul metro area and other locations). Ramp metering may reduce crashes around the I-29/I-94 interchange by as much as 50%.

Alternative Routing Systems at locations prone to flooding or other temporary closures can automatically update dynamic signage to give drivers a backup route when I-29 must be closed.

Virtual Weigh Station will include various commercial vehicle safety and pavement protection tools such as weigh-in-motion, tire anomaly, and infrared brake sensors.

Bridge De-Icing Systems use sensors to identify conditions conducive to bridge ice. Using nozzles embedded in the bridge, de-icing substances are sprayed on the road to improve friction and reduce crashes.

Electronic Road Closure Gates allow field staff to remotely close gates at safe locations. When gates need to be closed, roads are typically at their most treacherous. Remote operations will keep field staff out of harm’s way.

Wrong-Way Running Systems at targeted wrong-way running crash locations will use video detection and active warning signs to try to prevent drivers from entering off ramps.
