View from Traffic Management Centre
In line with one of the objectives of the Structural Plan Kuala Lumpur 2020 to improve the management of the Klang Valley's transport infrastructure system, City Hall Kuala Lumpur (CHKL) has selected Integrated Transport Information System (ITIS) to improve the planning and traffic flow in the city.
CHKL also expects ITIS to fulfill the need to gather, share and make available accurate and up-to-date traffic information to road users to help them ease their traffic woes in the Klang Valley.
Brief traffic information of what to expect along the way, such as road congestion, will offer both motorists and commuters some peace of mind as they can decide which road to take or to avoid and the best time to travel to get to their destinations easier, faster and safer.
A comprehensive traffic management system, ITIS will integrate the present road transport network as well as provide a communications interface for sprawling road systems in the Klang Valley and Multimedia Super Corridor (MSC) area.
How ITIS works?
At the heart of ITIS is the Transport Management Centre (TMC), which serves as the hub or nerve centre of the entire ITIS system as it receives, processes and disseminates traffic information around the clock. System operators will then use this information to monitor the transportation system operations and formulate strategies to enhance transport management.
TMC houses two core support systems of ITIS, namely the Advanced Traffic Management System (ATMS) and the Advanced Traveller Information System (ATIS).
A fully automated system, ATMS binds primary traffic data collected from Automatic Incident Detection (AID) system and Automatic Vehicle Location System (AVLS). The AID system detects traffic congestion on the roads while the AVLS provides real time travel database.
The system also manages the Closed Circuit Television (CCTV) surveillance cameras to monitor traffic situation and congestions. In addition, ATMS updates real-time road condition messages on Variable Message Signs (VMS) boards along major roads.

Information gathered on traffic situations and congestion will be sent to TMC for analysis and evaluation before being transformed into useful traffic information. TMC operators will use this information to formulate traffic management strategies such as maximising roadway capacity usage, reducing travel times and improving traffic safety.
At the same time, ATIS will deliver this real-time traffic information to road users and commuters in the form of a congestion map, travel speed map and incident map via the Internet (with support for wireless services) and Call Centre.
Road users will get updated information on road conditions and congestion via Variable Message Signs (VMS) units located strategically along major roads.
Intelligent Transport systems such as ITIS have been widely and successfully implemented in major cities around the world, bringing significant benefits to motorists and commuters.
Some of the benefits of ITIS:
- Allows informed decisions to be made on travel (i.e. choice of routes, modes and schedules)
- Enables real-time capture of traffic information for incident management and long-term transport planning
- Alleviates traffic congestion and delays during rush hour periods and emergency situations
- Reduces accidents, their severity and impact on the highway
- Improves emergency assistance for motorists and commuters
- Reduces travel times and promotes more uniform traffic flow
- Reduces pollution as a result of less time idling in traffic
- Provides comfort, safety and security in highway travel particularly around construction zones
- Improves utilisation of available road capacity
- Improves quality of life in the Klang Valley
