4. INTRODUCTION
Kajang,is a town in the eastern part
of Selangor, Malaysia.Kajang is the district capital
of Hululangat . It is located 21 kilometers (13 mi) from
Malaysia's capital, Kulalumper . Kajang town has grown
rapidly in the past several decades. New strategies for
traffic control must be developed in order to manage
the increase in traffic volume.

5. Traffic congestion and long queues at intersections
during peak hours is the major problems in Kajang
.Growing numbers of road users and limited resources
provided by current infrastructures lead to increasing
of travelling times. Inability of existing method in
determining traffic demand and provide suitable time
split when the traffic volume exceeds its capacity is
another main factor which lead to traffic congestion

20. PROPOSED TRAFFIC CONTROL CENTER
 The Traffic Control Center (TCC) is
the hub where all of the Kajang
City traffic control systems are
monitored. The TCC is proposed to
be located at the Kajang Town
Municipal Council Building and
allows the various components of
traffic management (signals,
control boxes, real time video and
simulations) to be effectively
managed by a team of traffic
engineers who monitor and
maintain signals throughout the
city

computer .The integration of these advanced
image sensors with high-performance
processors such as smart cameras .The basic
component of the image processing system
for the smart surveillance system comprises of
the smart surveillance camera, multiplexer,
image grabber and a Windows based
computer.

23. Traficon is one of the video detection systems
available , Traficon's continuous research has
resulted in solutions for traffic applications and
make the perfect traffic measurement system for
traffic applications, including ramp metering,
travel time calculation, dynamic speed indication,
queue tail monitoring, congestion monitoring,
tunnel access control, ventilation control,
rerouting, VMS-control

24. Traficon Principles
A video camera is installed at a certain
height for monitoring the traffic.
Its video signal is used as input for the
detection unit.
Application specific algorithms
provide different types of traffic
information
Traffic data for statistical processing
Incident related data
Presence data
The Traficon PC Software

25. Traficon Applications
Vehicle presence detection
Incident detection
Certain circumstances detection
Vehicles classifications
Vehicles speed measurement
Traffic counting

34. Internet Access
In Kajang Municipal area, Municipal Council and
JKR need to extend the webpage facilities to enable
the traffic information updated hourly or more
frequent to their existing webpage. The webpage also
can provides information on incidents, reports of
road closures, road works in the Kajang City.
Existing Webpage for Kajang Municipal Council31/5/2013 34

35. Car Navigation System
This approach was implemented
widely in develop country. But in
Malaysia recently the Navigation
system become popular to the
car user, nevertheless the system
is not interacting with the life
traffic at the road

36. Call Centre Radio / TV Station
 Kajang Municipal Council
and JKR suggested to set-
up one medium size call
centre or control centre to
provide information and
control the traffic in
Kajang area especially at
Kajang City Centre.
many radio and TV station
concern about their listener
and viewer demand (the
traffic condition at the
morning and evening peak
hours). So, the radio and TV
can collaborate with Traffic
Control Centre for the Kajang
City as example below:-
31/5/2013 36

37. SMS/MMS System or Personal Digital Assistant
By cooperating with the
telecommunication service
provider, the traffic condition
can be attained by the
communication tools which
are hand phone and personal
digital assistant (PDA)

38. OUTCOME
 The outcomes of this study are outline as below.
1-LOW COST SOLUTION:
Low cost solutions are the outcome of this study, ranging
from setting the optimum timing manually to an
intelligent system with communication system. The
intelligent system is based on distributed control system
using microprocessors whereas the communication system
is based on wireless system or system using power cable as
the communication medium to minimize cost.

39. PROPOSED COST OF INSTALLATION
In this section, we will list out the typical costing for installation of all the four
intersection with ITS.
31/5/2013 39

40. Calculating Congestion Costs and Reduction Benefits
 the cost of congestion is RM6.72 million/year compare to
setting up of ITS which is RM 2.07 million So we strongly
advise this KUTMS need to implement very soon to avoid the
price increasing and avoid the stress and waste of time for the
user and people in Kajang area.
31/5/2013 40

41. 4-SITE INSTALLATION
we propose to use wireless communication system. It was
considered the most cost effective and technologically
advantageous option considering existing needs, future
expansion needs and incorporation of other Intelligent
Transportation Systems (ITS).traffic management
components such as variable message signs, real time street
conditions based on street sensor feedback
31/5/2013 41

42. CONCLUSION
Multi-plan timing system could be set based on computed
timing that gives optimum traffic flows. The optimization
procedure includes individual controller setting and offset
timing to minimize stopping and maximize flows that give
progressive flows with maximum bandwidth. Optimizing
existing traffic controllers . It is undeniable that setting up
a ITS system in this Kajang town area would be a very wise
decision as it will help to lessen the congestion in Kajang
and also will benefits the town here as has smoother traffic
flow.

43. RECOMMENDATIONS
Upgrade the existing controllers to controllers with microprocessors
Install advanced sensors
Install communication system to facilitate data exchanges between traffic
controllers which are necessary in optimizing traffic flows.
Other recommendation if the congestion still cannot be manage by this
system are stated below:
Introduce road pricing within peak hour in the City centre
Road pricing for the operation and maintenance for the ITS system to reduce
the burden from the government. But the public transport system and
service must be upgrades prior to this road pricing implementation.31/5/2013

44. Introduce Response team during peak hour by
Municipal Council or JKR to control the traffic
during accident and incident happen at site
To introduce of prohibition for heavy vehicles
through the highway at peak times
