f. I-405 RTB — Toll rates are calculated as part of TMS where the traffic data is collected. WSDOT has developed and controls the calculation algorithm, to produce rates so that they are reflective of traffic conditions and distance traveled. The rates are posted to toll rate signs along the facility by the TMC and sent to the toll vendor FMAS to be matched with customer transactions and trips.

g. SR 167 ETL— Toll rates are calculated as part of TMS where the traffic data is collected. WSDOT has developed and controls the calculation algorithm, to produce rates so that they are reflective of traffic conditions and distance traveled.

h. Toll rate calculation and distribution for future lane toll systems

(1) Bridge, tunnel, and single-point toll facilities — Time of day toll rates are posted to toll rate signs by the TMS. Time of day toll rates are also held by the CSC, who matches scheduled toll rates
