Abstract
With the rapid increase of vehicles in use worldwide, the need for efficient traffic monitoring systems has arisen. This work proposes a low-cost vehicular traffic monitoring system using IoT devices and fog computing. The system is based on a three-tiered architecture which is composed of (i) the mobile tracking system that records the positions of the vehicles using GPS technologies; (ii) the information gathering system which gathers all the data collected by the mobile tracking system; and (iii) the fog devices that process the data collected and extract the information needed. The system is tested in the town of Corfu during a period of increased tourism when the traffic is considered to be relatively dense. The mobile tracking system devices are placed on taxis and with the help of professional taxi drivers the accuracy of the data collected is evaluated. The system is able to record the movement of the vehicles accurately using its own independent data. The results can be remotely accessed by utilizing fog and cloud computing infrastructure established to process the data and upload it on a server. The system is used to give a better understanding of the speed variance in the center of the town during different dates and hours. In conclusion the system presented in this study can be utilized to monitor the traffic and provide vital information about its behavior in relation to time.
Highlights
The issue of traffic congestion is a major concern to most road users for the last decades
It is observed that the average speed of the vehicles between 10:00 and 13:00 shows a major reduction, which can be explained by the fact that during these hours the traffic on the roads is significantly more dense compared to the aforementioned hours
The present paper proposes a low-cost vehicular traffic monitoring system using Internet of Things (IoT) devices and fog computing
Summary
The issue of traffic congestion is a major concern to most road users for the last decades. Based on the research carried out by INRIX Industries [2], which analyze global road traffic data, during the year of 2018 the annual cost of traffic congestion (per driver) ranges between 350 to 2500 euros. It is common knowledge that this issue can be responsible for bringing the urban road users to stressful situations, by stalling them from reaching their destination. This in result leads them to alternative routes through narrow and unfamiliar streets, increasing the likelihood of a road accident
