INTELLIGENT TRANSPORTATION SYSTEMS ARCHITECTURE

1. INTRODUCTION

The most challenging task at present is to obtain information about the roads in the network of city that is growing gradually. In order to overcome this issue, the ITS (Intelligent Transportation System) was originated so that the unique features will be benefited by the general public and information about the road can be obtained (Jin and Lin, 2011). The ITS is based on the technology of Bluetooth and (WSN) wireless sensor network. This device, sense the surroundings by the tiny and small device. The protocol used in the Bluetooth can be used to communicate with the vehicles that have Bluetooth device attach in it. ITS comprises of two major parts one is the infrastructure of transportation and the other one is the information technology in computer (Szpytko, 2009). The combination of both the features forms the ITS. The worst traffic situations and the major accidents or any emergency conditions can be resolved by using the facility of ITS (Ślęzak et al, 2010). The efficient architecture that will increase the road safety for the commuters is presented in this paper with the latest technology concepts of Bluetooth and wireless sensor networks. Additionally, the network formation of ad-hoc that senses between the vehicles and the exchanged data are explained. The results obtained from the simulation states that the sensor networks and Bluetooth technology can be used to increase the road safety.

2. IDENTIFICATION OF CHALLENGES

The WSN and wireless communications has developed the advanced technology of MEMS (Micro Electro Mechanical System). According to Katiyar et al, (2011), the wireless devices comprises of devices that are of very less cost have more facilities like storing, sensing and processing. The communication in the wireless mostly organized after the deployment of ad hoc fashion. The users are provided with the various facilities such as instrument, react to events and observe (Szpytko, 2009). The provided infrastructure comprises of sensing, elements of communication and computing. Mostly the places that are accelerated are being used to deploy WSN at present. Within 5-10 years the entire world will be using the internet to access the networks by using the WSN facility. At present internet is considered as the physical network. The development in the field of sensor networks is encouraged by the applications in military and surveillance. Controlling, monitoring and tracking are the major applications of WSN. The wireless sensor networks are spread in the specific area so that the sensor nodes can collect data. Many applications and industries such as civilian and industrial areas use the wireless sensor networks where the process of control monitoring, machine health monitoring, environment monitoring and applications in the healthcare and traffic control (Ezell, 2010).

The major challenge faced by the management authorities in traffic are the vehicle speed and the network position of the road. The main goal of WSN is to provide a solution for this issue faced by the traffic management. The ITS development and its infrastructure also get assists from the technology of wireless sensor network.

3. SOLUTION ARCHITECTURE

ITS will not match with the standards that have very less power like ZigBee as the vehicles will run in high speed. The vehicles with the sensors attached do not face any issue as the battery in the vehicle gets charged every time. The base stations that receive the information about the vehicles that are running on the road are deployed only in the important places. The received information is optimized and is served only to the needed vehicle. The ITS formation is done by combining the ad-hoc network, wireless sensor network, and by attaching the vehicles with Bluetooth devices.
