Sistema eletrônico de estacionamento rotativo

Abstract

A tariff system was deployed in areas of high traffic in Curitiba in order to democratize the occupation of public parking places. These places are called EstaR (from portuguese "Estacionamento Regulamentado") areas. However, this system is not so practical or convenient for the users, since it consists on paper pads on which the driver marks the parked time, ensuring his stay is regularized over the next hour. This process involves some problems such as the wasting of card when marking the wrong time, the payment of an complete hour even if the driver parked for a few minutes, the difficulty of finding a seller of those paper pads and the illegal sale of EstaR cards. This paper describes the study and development of an alternative to the use of paper pads. This alternative consists on a system on which a electronic device contain credits. The user presses a button to activate the discount of credits whenever is parked on a EstaR area. These credits are purchased through a website and each credit is equivalent to a minute parked. They are passed to the device by an USB cable attached to a computer. This system also has encryption algorithms to protect the credit information. This alternative seeks a fairer system where the user pays the actual parked time instead of paying the price for an hour even when he doesn't stays for this long.
