IoT for intelligent traffic system

This paper suggests a new schema for applying the IoT (Internet of Things) to intelligent traffic systems. The intelligent traffic system is implemented using road side units (RSU) with friction monitoring, vehicles with environmental sensors and a database for data transfer through different platforms. The system is able to collect sensor data from stationary RSU stations or moving vehicles and store it to the database. The test results indicate that the developed IcOR friction monitoring unit is able to distinguish the different road weather categories (ice, snow, wet and dry asphalt) with sufficient accuracy. Communication is implemented using a V2I/I2V IEEE 802.11p communication between RSUs and vehicles or 3G/4G mobile connections. In this article, we describe an implemented IoT ITS concept with current real-life implementation and future plans.

I. Introduction

Vehicles, road side sensor systems and supporting road infrastructure systems gather everyday information about the traffic environment. Installed road side systems are usually designed to work independently and provide measurements to only a restricted number of end-users; usually supporting road maintenance.
