As traffic passes the toll area at highway speeds, technology is hard at work, generating a toll transaction for each vehicle.
當車潮以高速通過收費站時，科技奮力在運作，替每輛車做過路費的處理。
Laser detectors sense a vehicle approaching, triggering the pass reader equipment. The reader searches for a Good To Go pass radio frequency.
雷射探測器感應到車輛駛近，觸發通行證讀取儀器。讀取儀器搜尋Good To Go通行證(類似ETC)的無線電頻率。
If the reader gets no radio frequency feedback, the system activates the license plate camera. The camera snaps a photo of the front license plate. A video camera records the whole tolling area for checks and balances. Treadles under the roadway count vehicle axles. A photo is also taken of the rear plate as a backup. The automatic system tracks four elements: time and date, Good To Go pass or license plate, and the number of axles, recording them in one transaction.
如果讀取儀器沒有接到無線電頻率反射，系統會啟動車牌相機。相機拍下前車牌的照片。一台錄影機拍下整個收費區域以供檢查及比對。在路面下的踏板計算車軸。也有一張後車牌的照片被拍下作為備用。自動化系統追蹤四樣要素：時間、日期、Good To Go通行證或車牌、車軸數，將它們記錄在一次的處理過程中。
Each transaction is transmitted instantaneously to the customer service center via fiber optics. For Good To Go transactions, the system double-checks the crossing time and number of axles to determine the toll rate, and automatically deducts the toll from the customer's account.
每次處理都立即透過光纖傳送到客服中心。就Good To Go的處理方面，系統複查通過的時間及車軸量來決定過路費，並自動從客戶帳戶中扣掉費用。
For pay by plate transactions, the system processes the license plate pictures to determine if the number is linked to a pre-paid account. If that plate number is already on an account, the system double-checks the crossing time and axle information to determine the toll rate,
and automatically deducts the toll from the pre-paid account.
就透過車牌繳費的處理方面，系統處理車牌照片來測定那車號是否有連結預付帳戶。如果那車號已經有帳戶，系統複查通過時間及車軸資訊來決定過路費，並從預付帳戶內自動扣掉過路費。
If not, after the system double-checks the crossing time and axle information to determine the toll rate, a bill is sent in a mail to the registered vehicle owner. That owner will have up to 80 days to pay the toll bill before a notice of civil penalty is issued.
如果沒有，在系統複查通過時間及車軸資訊以決定過路費後，帳單會以信件寄出到註冊車主。在民事罰鍰通知發出前，那車主會有最多80天的時間繳交過路費帳單。
