Intelligent Transportation System ITS Intelligent Transportation System
INTRODUCTION Traffic congestion-insufficient road development- growing number of vehicles. Low speed, increased accident rates, increased fuel consumption, and increased pollution These explore the concepts that treat highway systems and the vehicles that use them as integrated system. Among them is the concept of Intelligent Transportation Systems.
What is ITS ? International program aimed at using advanced technology for improving the efficiency , safety and environmental impact of land transportation. It is the Incorporation of information technologies and advances in electronics into all parts of the transportation network. It help drivers to navigate, avoid traffic holdups and avoid collisions

1.Vehicle Information And Communication System(VICS) ITS SYSTEMS 1.Vehicle Information And Communication System(VICS) It is a digital communication system. It provide real time road traffic information to the drivers via car navigation system Information is transmitted in the direction of traffic flow from beacons Steps in the operation of VICS 1.Collecting information 2.Processes and edits the collected information 3.Providing information
VICS provides three kinds of displays Map Display Simple Graphic Display Text Display
ADVANCED CRUISE-ASSIST HIGHWAY SYSTEMS(AHS) It provide information, warning and operational support for accident prevention by using use radio communication between road and vehicle Smart way enables a wide range of information exchange among all of ITS users It require functions capable of sensing road-environment data functions for generating guidance from road-environment data and road-to-vehicle communication

AHS ROADSIDE PROCESSING EQUIPMENT Image-processing subsystem: Use image processing to detect road obstacles and other vehicles, and to observe traffic Road-to-Vehicle Communications Roadside Equipment Networks
Advanced Traveler Information System: (ATIS) It provide drivers with real-time travel and traffic information Information about delays Help for optimal route selection There are three key steps to the provision of real- time traffic information: collection processing dissemination
Advanced Traffic Management System: (ATMS) Focus on traffic control devices Adaptive traffic signal control: to avoid bad signaling Ramp metering :to avoid vehicles entering into highway Three ATMS elements Collection data team Support system Real time traffic control system
Advanced Public Transportation Systems(APTS) APTS include applications such as automatic vehicle location (AVL) Each vehicle report their current location This system report the arrival and departure status of buses and trains
DEVELOPMENT AREAS ADVANCES IN NAVIGATION SYSTEMS: Portable GPS car navigation systems have become must have today for most drivers today It helps the driver to locate his position, while guiding him to his destination. The map provides a graphical picture of area It also provide turn-by-turn directions, visually as well as in form of spoken instructions
ELECTRONIC TOLL COLLECTION SYSTEM: An application of electronic signature detection to passenger and commercial vehicle traffic for the purpose of collecting tolls Allowing motorists to pass through the system at highway speeds Transponder: radio frequency identification unit that transmits radio signals
ASSISTANCE FOR SAFE DRIVING The three user services offered by this system are: Provision of Driving and Road Condition Information Danger Warning Assistance for driving
EMERGENCY VEHICLE NOTIFICATION SYSTEMS
AUTOMATIC ROAD ENFORCEMENT Consisting of a camera and a vehicle-monitoring device Used to detect and identify vehicles disobeying a speed limit or some other road legal requirement Speed cameras Red light cameras Bus lane cameras Level crossing cameras Double white line cameras Turn cameras at intersections
IN-VEHICLE TRANSIT INFORMATION SYSTEM
OBJECTIVES OF ITS Reducing traffic congestion; Smoothening the traffic flow; Reducing traffic accidents; Improving safety; Enhancing the mobility of travelers, especially the elderly and disabled; Reducing the use of energy; Reducing fuel consumption; Reducing pollution; Reducing capital and operating costs; Increasing the viability of public transportation; Responding more effectively to incidents; Increasing the ease and convenience of travel
ADVANTAGES OF ITS Improved safety. Better traffic flow. Lower travel cost. Better environmental quality. Increased business activity. Greater user acceptance. Better travel information.
DISADVANTAGES OF ITS Difficult to use in mixed traffic. Preliminary difficulties in understanding. ITS equipments costly. The control system software could be hacked by hackers.
CONCLUSION ITS represent the next step in the evolution of a nation's entire transportation system Traffic congestions, rate of road accidents, wastage of fuels are decreased to a large extend Transportation has become a safer and efficient mode Hence with much more interest and advanced research in the field of I T S, it can be implemented in our country and can prove to be the solution of the traffic problems including traffic congestion, air pollution and traffic accidents. This system will give a high progress in the devolvement of our country
