Desenvolvimento de dois dispositivos eletrônicos para contagem de tráfego e software para análise de dados

Abstract

This paper aims to explain the development of two electronic devices capable of performing the volumetric counting vehicles and software for data processing. One device consists of a hose sealed at one end and connected at the other end to a differential pressure sensor. This, in turn, is connected to an electronic circuit board responsible for making the processing data acquired through this sensor. This device will automatically perform the count, by detecting vehicles varying the pressure inside the pipe when they pass over it. The other device records the passage of vehicles through manual entries made by the operator. In this device, the operator must indicate the passage of the vehicle by pressing the corresponding button. The devices have battery power, LCD display and SD card for storage of data collected. Analysis of the data stored is made through a specific software, also developed in this work, which aims to treat the stored information and generate graphs and reports that allow the interpretation of collected data. The equipment and software are designed to assist those who perform vehicle counts as automate the process and reduce the number of people involved and can focus their efforts on analyzing the data in search of improvements in city traffic.
