What is a key benefit of using Electronic Toll Collection (ETC)?

The key benefit of using Electronic Toll Collection (ETC) is that it eliminates the need for toll booths. This technology allows vehicles to pass through toll points without stopping, as tolls are automatically collected through electronic transponders or license plate recognition systems. By removing the physical toll booths, ETC greatly reduces congestion at toll plazas, leading to smoother traffic flow and shorter delays for motorists. This advancement not only enhances the driver's experience but also expedites overall vehicle movement on the road network, supporting efficient transportation systems.

While other options may have some truth—such as potential reductions in emissions from decreased idling or benefits for future traffic measurement technologies—the primary and most direct advantage of ETC is its ability to streamline the toll collection process and remove the physical barriers associated with traditional toll booths.
