A trusted and secure environment for connected vehicle messaging.

REQUEST A DEMO

 

The Situation Data Exchange (SDX) is a one-stop shop for critical, authenticated traveler information – a centralized data retention and distribution source for connected and autonomous vehicle (CAV) information such as Traveler Information Messages (TIMs). Originally developed under funding from the United State Department of Transportation (USDOT) for its Connected Vehicle Pilot Program, Trihydro took over system ownership in early 2019. SDX supports CAV messages covering roadways for all 50 states.
With SDX, Departments of Transportation (DOTs) can distribute important traveler and work zone information to drivers, helping increase safety and creating efficiencies in traffic flow and route planning. The SDX is available as a standalone CAV messaging solution or as a complement to existing CAV infrastructure.

Trihydro’s value to the WYDOT CVP project cannot be overstated. We were all dealing with a first-of-its-kind effort and the Trihydro team was a true partner – from digging into requirements and helping to integrate technology in our Transportation Management Center to ensuring smooth rollout to stakeholders. We continue to enjoy our working relationship with Trihydro and would highly recommend them to other DOTs.
