BACKGROUND SITUATION OF PROMOTING ITS To Solve Social Problems caused by Road
To activate the Economy
To reach an Advanced Information and Tele communication Society
To Co-ordinate different Transport Modes

INTELLIGENT TRANSPORTATION TECHNOLOGIES
(1) Wireless Communications :
• Dedicated Short-Range Communications (DSRC) :
It offers communication between the vehicle and the roadside in specific locations (for example toll plazas) Applications such as Electronic Fee Collection(EFC) will operate over DSRC. It is a sub-set of the RFID - technology (Radio-Frequency Identification).
WWW.CIVILSCHOLAR.COM
Continuous Air interface Long and Medium range (CALM)provides continuous communications between a vehicle and the roadside using a variety of communication media, including cellular and infra-red links.
• Continuous Air interface Long and Medium range (CALM) :

(2) Floating Car Data/Floating Cellular Data :
• Non Real-time:– Manual surveys.– Video recording and manual search.– In-vehicle data recording.
• Real-time:– Automatic Number Plate Recognition (ANPR).– GPS trace + mobile comms e.g. GSM.– Radio Signal Triangulation.– Roadside beacon + dedicated short range tag.

(3) Inductive loop detection :
• One or more loops of wire are embedded under the road & connected to a control box.
• When a vehicle passes over or rests on the loop, inductance is reduced showing a vehicle is present.
• Benefits:
• Established Technology• Not impacted by
environmental conditions • Accurate in detecting vehicle
presence• Performs well in both high
and low volume traffic.WWW.CIVILSCHOLAR.COM
Radar and acoustic sensors are also used for detecting vehicles in the roadway.

(4) Video Vehicle Detection :Video vehicle detection (VVD) is the One of the most widely used method. Video detection is an image processor. It consists of a microprocessor-base CPU and software that analyzes video images.

INTELLIGENT TRANSPORTATION APPLICATIONS
(1) Electronic Toll Collection :• Today, most toll roads are
equipped with an electronic toll-collection system, like FASTag & E-Zpass, that detects and processes tolls electronically.
• FASTag is a device that employs Radio Frequency Identification (RFID) technology for making toll payments. Courtesy:HowStuffWorks

What are the benefits of using FASTag?
Environmental benefit Social benefit Economic benefit
• Reduced air pollution • Reduced use of paper
•Reduced toll payment hassles •Analytics for better highway management
• Reduced effort in management at toll plaza • Reduced effort in monitoring centrally
1.Ease of payment – No need to carry cash for the toll transactions, saves time 2.Near non-stop movement of vehicles leading to lower fuel cost. 3.Online Recharge – FASTag can be recharged online through Credit Card / Debit Card / NEFT/ RTGS or Net banking 4.SMS alerts for toll transactions, low balance, etc. 5.Online Portal for customers Other benefits are:

2) Variable Message Service:• Variable message signs (VMS) are traffic control devices used to provide
motorists en- route traveler information.
WWW.CIVILSCHOLAR.COM
• A traffic enforcement camera system, consisting of a Camera and a Vehicle-monitoring device, is used to detect and identify vehicles disobeying Speed Limit
(3) Automatic Road Enforcement :

Rollover Warning Road Departure Mitigation
Front-End collision warning WWW.CIVILSCHOLAR.COM
(5) Traveler Information Service :Information is Generated …
Traffic Sensor
Aerial surveillance
Weather Monitoring
Incident Detection
Transit Location
•Delay•Incident•Road Weather•Next Bus•Traveler Times•Emergency Alerts•Alternate Routes
