PrePass is an intelligent transportation system (ITS) that electronically verifies the safety, credentials, and weight of commercial vehicles as they approach participating state highway weigh stations. Because they comply electronically, commercial carriers enrolled in PrePass are authorized to bypass these facilities rather than pull in for ...
Approximately one-half to one full mile after passing under the "reader", the truck will pass under another boom which has an electronic unit to send the transponder a signal. If the safety information is acceptable, the truck may receive a green light and can continue without entering the weigh station at all.
Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site. . Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a st
Many ETC systems use transponders like this one to electronically debit the accounts of registered cars without their stopping.

It simply means how many transponders would be used if the same total bandwidths used only 36 MHz transponders. [3] [4] [5] So, for example, the ARSAT-1 has 24 IEEE K u band transponders: 12 with a bandwidth of 36 MHz, 8 with 54 MHz, and 4 with 72 MHz, which totals to 1152 MHz, or 32 TPE (i.e., 1152 MHz divided by 36 MHz).
