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
ITS ARCHITECTURE
ITS
INTELLIGENT TRANSPORTATION TECHNOLOGIES
5.Inductive loop detection
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
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
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:
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
