Though traffic management centers (TMCs) are essential to the operation of the current transportation environment, the introduction of connected and automated vehicles and smart sensors increases the amount of data that TMCs need to process. AI presents an opportunity to address some of the challenges that large influxes of data could bring.

Spotlight Project: AI Applications for TMCs

Through the SBIR program, FHWA worked with a private vendor and Delaware DOT to develop innovative traffic management systems using AI. One such system relies on real-time data from thousands of sensors along Interstate 95 and surrounding arterials to make operational recommendations to staff. The system tracks the incoming data and resulting operational outcomes to improve the system’s operational recommendations.

Mini-roundabouts are the small-scale versions of the modern roundabout traffic control system that directs vehicles circularly through an intersection. Mini-roundabouts eliminate the need to widen roads or relocate utilities, but, to compensate for their small size, the central islands and splitters are made traversable for trucks and large vehicles unable to complete the tight turns.

Spotlight Project: Recycled Plastic Mini-Roundabouts as a Traffic Control Solution

Through the SBIR program, FHWA worked with a private vendor to develop a mini-roundabout design that provides low-cost, easily installed, mini-roundabouts made from recycled plastic. While conventional methods require cutting the pavement and filling it with reinforced concrete, this new technology can be directly installed onto existing pavement in good condition.
