The Function of ETC Roadside System for Smart Interchange of Service/Parking Area Connection Type as a Social Experiment

Smart Interchange, a staff-less and cashless toll collection with dedicated Electronic Toll Collection system (ETC), will reduce the costs of operating tollgates and solve security problem of the gates. Smart Interchange requires only small structures and surface, reducing the construction cost. As well, function of interchange can be added to service / parking areas by connecting such areas with ordinary roads and installing ETC gates at the entrances and exits. It is greatly expected that the Smart Interchange will not only improve the convenience of using expressways and spread ETC further, but also revitalize the economy of regional communities that have currently no interchange, by providing access to expressways. This paper describes the function of the ETC roadside system for Smart Interchange of service / parking area connection type as a social experiment, and reports evaluation results of the system.
