RSE Payment Support	'RSE Payment Support' manages vehicle payments for road use, parking, and other fee–based services like vehicle charging. Road use payments are based on fee structures and payment strategies based on vehicle–reported data including VMT, emissions, vehicle class or type. Fees may vary by time or location and may include incentives or credits to reward desirable driving behavior. To support payment, it receives vehicle data (e.g., time stamped roadways used by the vehicle since the last transmission) and forwards this to the Payment Administration Center. It also receives equipment status from the vehicle and vehicle characteristics sensed from the vehicle (number of axles, weight, vehicle tag image/ID). Faults are identified and forwarded to the Payment Administration Center. Finally, it requests, receives, processes, and reports vehicle payment information.	False
