INTELLIGENT TRANSPORT SYSTEM

ABSTRACT:
Intelligent transport systems (ITS) are advanced application in which information and communication technologies are applied in the field of road transport, including infrastructure, vehicles and users, and in traffic management and mobility management, as well as for interfaces with other modes of transport. Intelligent transport systems technologies applied in car navigation, traffic signal automatic number plate recognition or speed cameras to monitor applications, such as security CCTV systems parking guidance & information systems, weather information, bridge deicing systems. In this technology, wireless communications are explained as short range & long range communication. Recent advances in vehicle electronics have led to a move toward fewer, more capable computer processors on a vehicle. "Floating car" or "probe" data collection is a set of relatively low-cost methods for obtaining travel time and speed data for vehicles. We explained this floating car in three methods to obtain the raw data- Triangulation method, Vehicle Re-identification, GPS based methods and inexpensive intelligent beacon sensing technologies, have enhanced the technical capabilities that will facilitate motorist safety benefits for intelligent transportation systems globally. Sensing systems for ITS are vehicle- and infrastructure-based networked systems, i.e. intelligent vehicle technologies. Bluetooth road sensors are able to detect Bluetooth MAC addresses from Bluetooth devices in passing vehicles. Emergency vehicle notification systems is the most important application of ITS.

INTRODUCTION:
Intelligent transport systems (ITS) are advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management and enable various users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks. Although ITS may refer to all modes of transport on the framework for the deployment of intelligent transport systems in the field of road transport and for interfaces with other modes of transport defines ITS as systems in which information and communication technologies are applied in the field of road transport, including infrastructure, vehicles and users, and in traffic management and mobility management, as well as for interfaces with other modes of transport. INTELLIGENT TRANSPORT TECHNOLOGIES

Intelligent transport systems vary in technologies applied, from basic management systems such as car navigation, traffic signal, control systems, container management systems, variable message signs, automatic number plate recognition or speed cameras to monitor applications, such as security CCTV systems and to more advanced applications that integrate live data and feedback from a number of other sources, such as parking guidance and information systems, weather information, bridge deicing systems. 1.WIRELESS COMMUNICATIONS

Various forms of wireless communications technologies have been proposed for intelligent transportation systems. Radio modem communication on UHF and VHF frequencies are widely used for short and long range communication within ITS. Short-range communications (less than 500 yards), specifically WAVE or the Dedicated Short Range Communications standard being promoted by the Intelligent Transportation Society of America and the United States Department of Transportation. Longer range communications have been proposed using infrastructure networks such as WiMAX (IEEE 802.16) Global System for Mobile Communication (GSM), or 3G. Long-range communications using these methods are well established, but, unlike the short-range protocols, these methods require extensive and very expensive infrastructure deployment. There is lack of consensus as to what business model should support this infrastructure. 2. COMPUTATIONAL...
