Electronic toll collection system is an automated system, eliminating manual operations by toll payers and receivers. The global ETC market is expected to steer towards a strong double-digit growth rate in the coming five years (2015-2020). The primary drivers of the upcoming growth comprise the need to save travel time, cashless travel facility, the need to stop/minimize the traffic congestion and fast toll transaction. However, factors like high installation cost and a high dependence on government are hindering the growth of this market to some extent. The ETC market is expected to continue its rapid expansion to meet the surging demand for an improved, safe and secure infrastructure. The ETC system provides fast, efficient and cost-effective services. They have easy to operate buttons with a user-friendly design. They are also beneficial for traffic agencies and companies as these systems eliminate the need for multiple toll plazas, acting as a cost-saving factor for road operator agencies. Electronic toll collection systems have a positive impact on the environment as it reduces the amount of exhaust emitted from vehicles during start-up and stop at manual toll booths.
The ETC market can be categorised into products, technologies, applications and geographies. Transponders, antennae, communication systems, treadles, inductive loops, scanning devices, weigh-in-motion devices, cameras and film storage devices are some of the major products of the system. An electronic toll collection system consists of various subsystems, such as automatic vehicle identification (AVI), automatic vehicle classification (AVC), back-office &integration and violation enforcement system (VES). These subsystems are useful for specific functions -AVI for vehicle identification, AVC for vehicle classification, toll collection transaction by integrating the back-office and payment system and VES to reduce unpaid tolls, by vehicle imaging.
