26
11/2/2015GANESH SJ

Inductive Loops
• Small slots are crated by copper wire in road
• Current is passed through this loops
• During movement of vehicle electromagnetic induction occur
• Difference is collected by single/dual loop detectors
• Used at highway segment and intersections
• It is help for counting vehicle number
27
11/2/2015GANESH SJ

Video Image Detectors
• Best method for data collection
• Help for calculating traffic volume
• It can focused to a point
• When a vehicle enter the target area camera ON ,
when it move out detectors will automatic OFF

Automatic Warning System ( AWS )
• AWS providing signal to train 185m before stopping point
• Controlling of train done by electromagnetic method
• Major parts – Control box, Connection valves, Indicators on cabin
and a locomotive part
• Need 12V – 40V for normal use
• AWS provide speed restriction signals also

Working of AWS
• A sound bell created at driver’s cabin when message received
• AWS provide sound bell until the driver applying break
• If the driver fail to apply break the train will stop within 6 seconds
• Electromagnetic method used for it

ATIS IN INDIA
Case study-ATIS in Chandigarh
( Dhanunjaya Reddi .et.al)
• Chandigarh is the only place in India where ATIS installed (2010)
• GIS is the platform for this
• Arc GIS10 software used for controlling all the operation
• It can store the data of 5000 major and minor roads
• 300 ATMs,150 Hospitals, 170 Schools and colleges
48

SUMMARY
• ATIS is very useful to overcome the traffic congestion problem
• Automatic working will save National Income
• Initial setting cost of ATIS is very high
• Traffic problem in India can easy to solve by this
• Lac of land consumption is the major problem
• I think Installing ATIS at Trivandrum and Vyttila Ernakulam
help to solve traffic problem
