Smart mobility, a sustainable alternative for a developing city. Case study: Azogues, Ecuador

Abstract

Context:  Main streets of Azogues city, developing and sustainable cities in the improvement and development in electric vehicles applications.

Problem: High percentages of congestion due to lack of control in vehicular traffic in the city main streets, environment pollution and noise.

Aim: Telecommunications network planning allows the smart traffic lights im-plementation, with the analysis of the necessary elements for its correct operation and the vehicular congestion reduction in the main streets of the Azogues city cen-ter. Besides, the implementation of improvements on a basic electric vehicle al-lows, by means of sensors and actuators, to improve its performance and security.

Methodological proposal: Scientific and experimental methodology, used ob-servation techniques, simulations and operation tests, with test and error analysis until getting an efficient system. Experiment: Creation of a Web application inte-grated with a MySQL database, which contains all the users who can access the application to be able to manipulate it. Followed by the development of user con-trol tables, the control and monitoring of the smart traffic lights was carried out, developed on PHP, with the purpose of  graphically visualizing the system; that is, this screen must be capable of indicating the traffic lights that are being monitored, the state they are in, and buttons with which the traffic lights can be controlled. It was found that the most appropriate way to configure the speed of a WiFi module is through AT commands, which are compatible with Arduino and with which said configuration allows the module to operate at 99.9% of its performance. In the electric vehicle, the programming and activation of the different sensors were de-veloped, which use libraries already developed to activate each of them. Arduino was used because it is self-contained. The libraries needed for this project were hosted on GitHub. The electrical connection was made using cables and relays, for the automatic activation of the sensors, and the signal was obtained directly from the control card.
