ABSTRACT From past few years some new intelligent technologies have made excellent improvisation in transportation system’s performance. For better transportation, the concept Intelligent Transportation System (ITS) is used to increase safety and traveler’s convenience and reduce traffic congestion. ITS is not just getting from one place to another, but getting there by safer, greener and more convenient way. This paper presents enhanced ITS with road side unit (RSU) using the concept of internet of things (IoT). In this paper, RSU uses Raspberry Pi Board as a main component to collect the real time information using various sensors and on-board camera and conveys it to the driver for better travelling experience. The proposed system is flexible and helps to communicate through ITS entities like vehicle to infrastructure (V2I) and infrastructure to infrastructure (V2V) communication. ITS helps to grow and develop smart cities, urban areas with less accident rate and improve road safety. Keywords: Intelligent Transportation System (ITS), Internet of Things (IoT), Road Side Unit (RSU), Vehicle Unit (VU).

INTRODUCTION

The main issue in transportation is the traffic congestion and this traffic congestion effects environmental issues like carbon emission and air pollution. ITS is used to reduce traffic congestion, and improves road safety. The information related to the traffic congestion and environmental conditions is processed and proper decision is created to convey it to the traveler [1][2]. Various wireless communication technologies are implemented by ITS which enhances the communication between the RSU infrastructure and VU. In this paper, the designed system uses internet of things (IoT) wireless technology which has good communication and computing capabilities to collect the real time information from the RSU and gives updated information which makes transportation system a smart infrastructure [3]. IoT works in various fields specially in smart cities for smarter infrastructure, traffic management, parking and transit services. IoT allows people and various objects to be connected anytime and anywhere with anything and to any service with real time communication. Another wireless technology used in this system is Zigbee S2C module. Zigbee S2C module is a RF (Radio Frequency) module which sends the data serially from RSU to the VU. RSU collects the real time information like weather conditions, traffic congestion and conveys it in two ways which are: through Zigbee serial communication where it passes the information to nearby passing vehicles and other is through cloud where the web page will show the real time information of the RSU. RSU uses Raspberry Pi as the main unit where it collects the needed information from sensors and conveys it to the users. Raspberry Pi 3 Model B is used by the RSU which is a third-generation model with Broadcom BCM2837 ARM Cortex A53 Quad Core Processor which runs 50% faster than previous versions of Raspberry Pi. In the development of intelligent transportation system, various forms of wireless communications technologies were implemented. For short range and long-range communication within ITS radio modem communication UHF and VHF frequencies are widely used. Some of the major wireless technologies are wireless personal area networks (Bluetooth), wireless local area network (Wi-Fi), wireless metropolitan area network (WiMax), wireless wide area network (3G/4G mobile network) and satellite network (GPS) [4]. Some innovations show the design of RSU with Adaptive Speed Limits (ASL). Road accidents occurs because of excessive vehicles speed www.irjmets.com
