It is understood by capacity or vehicular count, to the determination of the volumes that pass in a sense and for a certain place within a defined period of time, procedures used to find these volumes are varied, some more effectively than others, which is why it is important to optimize the procedure in terms of reliability, use of resources and times. Fort he above, and with the continuous increase in the country's automotive fleet and the consequent road expansion, it is necessary establish efficient and practical vehicle capacity or counting methods in a way that impacts the environment as little as possible and at the same time, accurate data are delivered to less time, that is why we see the need to create a computer tool that allows you to develop these counts on mobile devices and determine exact quantities and categories, in this document, you will find the description of said tool, how to use it and benefits that brings with it the elimination of paper use, shorter processing times, greater accuracy and reliability of information and others.
