Building Internet Of Things, (Iot) Based Smart Parking System For Addis Ababa City

Abstract

Getting free parking area in Addis Ababa city in the whole day especially in the morning and in the afternoon, is difficult. In the city drivers were searching parking stations without any aid; this led to wastage of fuel and time, traffic congestion, air pollution, accident and driver frustration. So, Building IoT based smart parking system architecture for real time application has significant roles to solve the above problems because IoT technology uses set of devices that have identities and virtual personalities operating in smart spaces using smart interfaces to connect and communicate with the physical environments. Interconnected devices to communicate with each other or to another machine on the network have increased the number of applications. To investigate the existing parking problems observation and interview was conducted in different areas and in different organizations in the city. After analyzing the problems smart parking system in this study was developed using ultrasonic sensor, Arduino Uno, 16?? 2 LCD, GPS and EPS8266 Wi-Fi module and the hardware was simulated by proteus professional software simulator with Arduino IDE using C++programming language. The architecture of the smart parking system was developed using reference based architecture by considering hardware device and software tools. The smart parking system was implemented on Apache Cordova framework for hybrid mobile application. The web application of smart parking system was implemented and connected with mobile applications and local server implementation of hardware in each parking stations. To get the smart parking system services each local server and the central server communicated continuously about the status of parking, location of parking and users or drivers request. The driver can access parking services by installing mobile applications on their mobile phon. The smart parking system architecture, the free slot availability, the location and the speed of the system was evaluated and analyzed. The smart parking system was evaluated to check the working functionality of the system using different test cases especially in free slot identification and location identification in different parking stations and also the speed of the system was evaluated by software professionals. Based on evaluation test cases results was analyzed to achieve the goal and the objective of the smart parking system.
