2. INTRODUCTION
Kajang is a town in the eastern part of Selangor,
Malaysia. Kajang is the district capital of Hulu Langat. It
is located 21 kilometers (13 mi) from Malaysia's capital,
Kuala Lumpur.

3. PROBLEM STATEMENT:
The traffic at the intersection during peak hours is
regularly and very crowded as results to the huge
number of cars reaching the carrying capacity of the
road. Long queues at the intersections are another
problem facing traffic stream. Also the increasing in
growth population and number of condominiums that
inhabited by foreign students those came from different
countries, will also increase number of cars that will run
all streets of Kajang additional to the local people.

4. OBJECTIVES OF STUDY:
 An alternative solution will be presents to solve out the
traffic jam at the intersection during peak hours.
 The capacity of the will increase and the movement of
vehicles will become a streamline and more fluent.
 Deploy ITS technologies (VMS, CCTV,
Communication System, etc.) to ease traffic stream
and movement among the city-centers.
 Decrease travel time from residential area to the
commercial area for example from Pearl Avenue to
Kajang Town to the half at least.

5. AREA OF STUDY:
To study the traffic condition in Kajang we
propose three intersections as to represent Kajang
city, one intersection that located in residential area
(Taman Sepakat Indah), the other two are located in
the heart of Kajang city (Sungai Chua), represented
an offset successive intersections.

OF THE SYSTEM:

14. The ITS Architecture Is Comprised Of
Three Layers
 The Institutional Layer
 The Transportation Layer
 The Communications Layer

17. ADAPTIVE TRAFFIC CONTROL

18. (SCATS) ADAPTIVE TRAFFIC SYSTEM
SCATS® is a fully adaptive urban traffic control system that
optimizes traffic flow. Its self-calibrating software minimizes
manual intervention, which can result in substantial
operational cost savings.

19. HOW SCATS WORKS?
SCATS - Objectives and Installations:
 Minimize Stops (light traffic), delay (heavy traffic) and
travel time.
 SCATS is installed in many cities worldwide.
 There is approximately 5000 intersection under, SCATS
control around the world.
 Largest systems are: Sydney (2000 intersections),
Melbourne (2000), Hong Kong (600) and, in the US,
Oakland County MI (350).

20. CHOOSING SCATS FOR YOUR TOWN
 Reduced costs
 Proven performance
 A global traffic solution
 Highly configurable
 Flexible integration
 Ongoing software improvements
The benefits are:
 Reduced air pollution.
 Reduced fuel consumption.
 Reduced delays.
 Enhanced public transport time and reliability.

21. THE SMART SURVEILLANCE SYSTEM

22. PROPOSED (ITIS) IN KAJANG
Integrated Transport Information
System (ITIS) is a comprehensive
traffic information system for
Kajang City to monitor traffic
flow and analyze the data on road
conditions to provide useful
traffic information to road users.

23. PUBLIC TRANSPORT MANAGEMENT
SYSTEM
 Existing Systems
 Overview
 Management Software
 Time Management.
 What We Hope To Learn?

24. VARIABLE MESSAGE SYSTEM (VMS)

25. PORTABLE DYNAMIC MESSAGE SIGNS
Variable message signs are the safest
means for notifying motorists of
changes in traffic patterns and road
conditions.

26. COMMUNICATION SYSTEM
 Communications system configuration and update
management:
 Regulatory compliance, e.g. compliance with national
spectrum usage rules.
 Recording and forwarding of usage billing events.
 Communications system fault monitoring
 Maintenance utilities
