2. Introduction
 The term Intelligent Information Systems(ITS) refers to the information and
communication technology applied to transport infrastructure so as to
improve the overall efficacy of:
a) Transport Safety
b) Transport Productivity
c) Travel Reliability
d) Informed travel choices
e) Network Optimization
f) Environmental Performance
 While implementing ITS the basic guidelines to be kept in mind are:
a) Where and Why is the system required
b) Use the principles of efficiency to optimize performance

3. Need for ITS

4. Applications
TRAFFIC REGULATION
 Triangulate the position of traffic units and suitably determine the
requirement(according to the business problem) in a particular area.
 Incident Detection
 Variable Speed Limits
 Ramp Control

5. TRAFFIC REGULATION
 Demand Responsive Traffic Management
 Parking Management
 Dynamic Freight and Fleet Management
 Traffic signal control

6.  Vulnerable Road User Systems
Eg. Puffin-Crossings
 Multimodal Trip Planning
 Passenger Information Systems
 Route Guidance and Navigation

7.  Variable Message Boards
and route guidance
 Road user charging
tolling and access control
 Smart public transport payment
 Speed detection and
E-challan

8. Decisions that affect
Implementation
 What are the transport policy objectives??
 How much can be spent??
 Is the existing technology compatible with ITS??
 Is the technology tried or tested
or are we the pioneers??

9. OysterCard
LONDON, UK
 Ticketing done through value stored in Cards for buses, metro rail.
 Contactless- Speeds up the boarding process by making it simpler.
Infrared billing, automatic deduction of fare from the
card
 5mil cards, 3 mil trips per day.
(32% of the daily traffic)
 Has the addd advantage of offering big discounts over the usual
‘pay per trip’ model and huge discounts offered.

10. PARK-Assist
Aalborg, DK
 9 Car Parks, 17000 Parking spaces,
108 VMS signs for assistance.
 Real time assistance on car occupancy
- Guidance to the vacant parking spot.
 Saves 12000 hrs/year
simultaneously making the parking
and exiting process much smoother
 24% increase in the no. of car-owners using these facilities
3% decrease in emissions due to lesser waste time wasted.

11. Rome Access Control
Colosseum, ROME
 Intelligent entry and exit system
 Charges levied based on:
- Previous visits and frequency
- Variable Charges based on traffic
 TELEPASS technology used
- Infra-red cameras used.
- Microwave transponders to comunicate
- In vehicle micro cards used
 15-18 % reduction in the traffic delays
- 6% decrease emission, 31% decrease noise

12. Continuous Air Interface Long and
Medium Range
 It provides continuous communication between the roadside and the vehicle to
provide constant upstream and downstream transfer of necessary information.
 For the same it uses myriad media such as
- Cellular Network
- Internet
- Infra Red Networks
 Some of the applications include:
- Smart data transfer for better maneuver, control, navigation and route location
- Entertainment
- Data for future analysis

13. Floating Cellular Data
 These are the available Car Data Detection Techniques
 NON-REAL TIME
- Manual Surveys
- Video Recording and Manual Search
- In-Vehicle Data Recording
 REAL TIME
- Not Induction Loop(without transponder)
- Automatic Number Plate Recognition (ANPR)
- Radio Signal Triangulation
- Roadside Beacon + Dedicated Short Range Tag

14. Emergency Vehicle Notificaton
Systems
 Floating Car Data
- Used to provide advance notifications to motorists
in case there is any distraction in the path and using this
the impending traffic block and the mayhem can be
avoided.
- Alternative Routes
- Dynamic Directions based on traffic density
- Advise in case of an accident so that a
problematic route can be avoided

15. Sensing Technologies
 PAVEMENT LOOPS
- Used to sense the presence of cars
at busy intersections and also parking
lot entrances.
- Strategically used they can easily be
used so as to improve efficiency.
 PRESSURE PADS
- Used to sense the presence of
pedestrians that are used to detect
pedestrian density and according
signals can be manipulated.
