—

Backhaul security refers to the processes used to ensure that someone doesn’t hack into the traffic control system through the Roadside Equipment (RSE).

Vehicles and aftermarket safety devices (ASDs) communicate wirelessly with the RSE.  The RSE communicates with the signal controller which in turn communicates with the operations center.  The RSE also communicates with the certificate authority.  All pose concerns for backhaul security, which we are actively working to address in concert with our stakeholders.
