2. INTRODUCTION
Intelligent Transport Systems are advanced applications
which without embodying intelligence as such ,aim to
provide innovative services relating to different modes
of transport and traffic management
It enable various users to be better informed and make
safer , more co-ordinated and smarter use of transport
networks
ITS refers to all modes of transport
It is the system in which information and communication
technologies are applied in the field of road transports
and traffic management
3. Intelligent Transport Technologies
Computational Technologies
floating car data is collected by 3 methods
they are: 1.Triangulation method
2. Vehicle re-identification method
3. GPS based method
Sensing technologies
1. Inductive loop detection
2. video vehicle detection
3. Bluetooth detection
4. Triangulation Method
In this method,cars containing mobile phones
transmit the presence information to mobile
phone network.
5. Vehicle Re-identification
In this method a set of detectors are mounted
along the road
A unique serial number for a device in the vehicle
is detected at one location and then detected
again further down the road
6. GPS Based method
In this method an increased number of vehicles
are equipped with GPS systems that have two
way communication with traffic data provider
Position readings from these vehicles are used to
compute vehicle speeds
7. Inductive loop detection
In this method
inductive loops are
placed in a road bed to
detect vehicles that
pass through loops
magnetic field
These detectors count
the no of vehicles
during unit time
8. Video vehicle detection
In this method cameras
are mounted on poles
adjacent to road way
This video detection
processor detect traffic
speed from 1 to 8
cameras
9. Bluetooth detection method
Bluetooth road sensors
are able to detect
bluetooth adresses
from the bluetooth
devices in passing
vehicles & inter
connected and provide
data for origin and
destination analysis
