Aesthetics and savings from gantry-free system

摘要

Current free-flow toll systems employ either 5.8GHz DSRC or 860-960MHz RFID technologies. Such systems are deployed on motorways or at city entries and more often than not require heavy-duty overhead gantries or infrastructure at each point of payment to accommodate tag detection cameras, and vehicle identification and classification equipment. However, these imposing and unaesthetic structures ruin landscapes and urban environments, not to mention the very high investment for civil engineering and maintenance. Furthermore, there are a great number of complaints relating to the technical limitations of such existing facilities.
