OVERVIEW OF THE PROJECT
Purpose

The goal of this project was to take a parking lot control system from requirement generation, through model generation and validation. This document describes the process taken a presents the resulting data.

Roles and Responsibilities The project team is formed by the following students: Atul Mehta and Felipe Leite. Since all team members have the same experience and expertise designing systems, the work was divided equally and assigned arbitrarily. Introduction For our project, we have decided to design a system that can be deployed in existing parking structures which would provide information about available parking spaces to drivers trying to access the facility. The system will include software, sensors and the networking components. The installation of permanent sensors in each parking space will provide lot owners with constant and accurate information on parking lot occupancy. This allows them to keep the lot at full capacity and serve customers better. Figure 1 shows the building parking lot that we will be designing for. It has 72 parking spaces where 8 are handicap, 4 are for the building staff and the remaining 60 are available for regular lot users. In addition, a list of members provided to the system by the...
