This presentation describes a system for effective tolling on highway projects. Th epresentation briefly describes and explains the system and can be useful for people trying to figure out how the system works effectively and efficiently

1. Tolling Systems

4. BOOM BARRIER PRESENCE LOOP EXIT LOOP TOLL COLLECTOR WITH PRINTER & SYSTEM TRAFFIC LIGHT UFD BRIEF ON LANE EQUIPMENTS OHLS HEIGHT SENSOR CSC READER TAG ANTENNA TH

6. OHLS SHOWS WHETHER THE LANE IS OPEN OR CLOSED. GREEN = CASH BLUE = CSC ORANGE = TAG GREEN = OPEN LANE RED = CLOSED LANE

7. Vehicle enters the Toll lane VECHILE ENTERING IN LANE

8. Vehicle on Presence Loop

9. TRAFFIC LIGHT IS RED, UFD SHOWING THE MSG ASKING FOR PAYMENT DUE

10. Vehicle passing through AVC area

11. Vehicle departs from the Lane ** THE EXIT LOOP RETURNS TO NORMAL STATE AND SENDS MSG TO THE BOOM TO CLOSE. TC CAN PROCEED WITH THE NEW TRANSACTION.

12. The Collection Process TC has to do a physical verification of the vehicle and class it accordingly EG: Class 01 Method of payment is done by the TC according to the user EG: Cash Automatic Vehicle Classifier is the system check on the TC class EG: Class 01 Avc will send a message to TC and give clearance to process next vehicle.

13. Vehicle direction Entry Loop Exit Loop Treadles: Count and DWD Height Sensors Boom Barrier Loops generates magnetic field in the road to detect the presence of a vehicle. Treadles are used for counting axles and for double wheel detection. Height sensors at various heights will help identify height parameters between different class of vehicles. Boom barrier will open once MOP has been given and will close on clearance of Exit loop.

14. If there is an AVC discrepancy TC has to do a physical verification of the vehicle and class it accordingly EG: Class 01 Method of payment is done by the TC according to the user EG: Cash Automatic Vehicle Classifier is the system check on the TC class EG: Class 06 Avc will still send a message to TC and give clearance to process next vehicle, but an image will be taken of the vehicle and sent to Validation.

16. Routing and Storage of Transaction Files

17. Data Management of Transaction Files
