Introduction : Automatic vehicle location (AVL) is a computer
-based vehicle tracking system by using the satellite and land communication.
This system use GPS technology in tracking vehicles and protect the precious goods
This system send the information regarding actual location, heading and status of vehicle is determined and relayed to control center
OBJECTIVES Evaluate the effectiveness of the AVL
system Demonstrate the capability of AVL
technology to:- Improve dispatch process- Optimize traffic signal timing- Collect traffic engineering data
Technologies employed for AVL GPS (global positioning system) dead reckoning Odometer system Radio navigation
AVL system architecture
Working of a GPS based AV L:
1.GPS satellites: GPS satellites calculate The information
regarding the location of the transit vehicle is by TRILATERATION method.
The GPS unit in the vehicle absorbs the signals from GPS satellites And send those signals to the RADIO system.
2.Radio system: The RADIO systems receive the vehicle GEO -LOCATION
coordinates and transmits this radio signals to Communication center
3.Communication center: The communication center receives the information from
radio system. uses it to determine the location of transit vehicle and sends this to customer assistance unit through wire line or wireless networks.
4. Customer assistance unit: This section use vehicle location map to help and provide
traffic information for other road way driver.
working of AVL technology using GPS:
Working of a GPS based AVL
TRACKING SYSTEMS The AVL tracking system consists of a GPS
receiver inside the vehicle
.
There are two types of tracking systems are there 1.Passive tracking system 2.Real time tracking system
o 1.Passive systems are refers to stand alone GPS receivers
o Passive systems are typically limited to vehicle tracking only.
o When a passive systems are installed in the vehicle the location, time status and heading of the vehicle data are usually transferred to their base station
Real time tracking systems:
o Real time tracking systems are based on mobile terminals which combine GPS and GSM technology
to determinate and transmit their vehicles position.
In this two-way wireless communication link connects the GPS unit with the control center at all times.
APPLICATIONS IN OTHER FIELDS:
In cargo Child Tracking
1.IN CARGO :A small GPS receiver inside the cargo can know exactlywhere it is, how far it is from the destination, and where tofind even it if it is stolen.
Child Tracking: ‘child tracking', giving the possibility for children
to wear or carry some sort of GPS/GSM tracker. Such a device could provide valuable information if a child is abducted or lost.
Signals could be sent from the tracker to a central site when a ‘panic button’ was pressed by the child.
BENEFITS: 1. Vehicle location display in real-time. 2. Recording of arrival and departure times
vehicles 3. to the know position of cargo where it is 4. Alerts if vehicle leaves or enters a defined area 5.Child Tracking
conclusion If we are using this AVL technology we can
protect our vehicles ,cargo sand child's. we know about the vehicle actual location ,status
and speed.
