Introduction Kajang is well connected with many major highway and

expressway like Kajang Dispersal Link Expressway as a ring road of Kajang,Cheras-Kajang Expressway (CKE, E7),North-South Expressway (NSE) (Malay: Lebuhraya Utara-Selatan) with Kajang exit and Kajang-Seremban Expressway (LEKAS, E7) at the south of Kajang near Semenyih. Because the position of Kajang between three major city (Kuala Lumpur, Seremban and Putrajaya), this city is included in Klang Valley or Greater Kuala Lumpur. Public transport available in Kajang are bus, taxi, and train; Therefore, Kajang is in quick development and must to be installed a new full equipment ITS to fulfill the needs of the city.

The Architecture View of ITS

The architecture view is an interconnected presentation of all of the components of the ITS Architecture. A variety of entry points allow you to start with any of these components. Once in, you can easily navigate from component to component to find what you need. This view of the architecture is possible because of the traceability that is maintained between each of the architecture components.

The Architecture View

The Architecture View

The ITS Architecture is comprised of three Layers. The Institutional Layer includes the institutions, policies,

funding mechanisms, and processes that are required for effective implementation, operation, and maintenance of an intelligent transportation system.

The Transportation Layer is where the transportation services are defined in terms of the subsystems and interfaces and the underlying functionality and data definitions that are required for each transportation service. This is the heart of the ITS Architecture.

The ITS Architecture focuses on system integration and system integration requires effective communications. A general description of the communications services and technologies that support ITS is defined in the Communications Layer.

the Communications Layer

The ITS Architecture provides the framework that ties the transportation and telecommunication worlds together to enable the development and effective implementation of the broad range of ITS User Services.

The CommunicationsLayer of the Physical Architecture identifies fourmajor types of communication to support the communications requirements

Field - Vehicle Communications

A wireless communications channel used for broadcast and interactive close-proximity communications between vehicles and the immediate infrastructure.

Fixed Point - Fixed Point Communications

A communications link that provides communications among stationary entities.

Vehicle - Vehicle Communications

A short range wireless communications link among vehicles (e.g. mobile system to mobile systems).

Wide Area Wireless (Mobile) Communications

A wireless communications system that offers broad coverage, enabling communications with vehicles and traveler mobile devices at any location on or off the road network.

The Transportation Layer

The Transportation Layer defines the functions that are performed, the subsystems that provide these functions, and the interfaces that are required to support the ITS User Services.

This layer, the heart of the ITS Architecture, provides a framework for applying technology in a consistent, progressive, and effective fashion to improve the surface transportation system.

The Transportation Layer

the Transportation Layer also defines terminators that represent all of the other systems, people, and physical conditions that the surface transportation system must interface with

These two types of architectural components (subsystems and terminators) are called entities:-- Center- Field- Vehicle- Traveller(will explained later)

The Institutional Layer

The Institutional Layer considers the policies, funding incentives, working arrangements, and jurisdictional structure that support the technical layers of the architecture.

The Institutional Layer provides the basis for understanding who the implementers will be and the roles these implementers could take in implementing architecture-based ITS systems.

The Logical Architecture

The Logical Architecture defines the Processes (the activities and functions) that are required to provide the required User Services.

Data Flow Diagrams (DFDs)

The Logical Architecture is presented to the reader via Data Flow Diagrams (DFDs) or bubble charts and Process Specifications.

The physical architecture

The physical architecture is a physical representation (though not a detailed design) of important ITS interfaces and major system components. The physical architecture identifies the transportation systems and the information exchanges that support ITS.

The physical architecture forms a high-level structure around the processes and data flows in the Logical Architecture. The Transportation Layer defines the Physical Entities (Subsystems and Terminators) that make up an intelligent transportation system.

Smart traffic lights A new system that combines existing

technology with artificial intelligence to create lights that truly think for themselves’.

 Smart Surveillance System

Smart surveillance, is the use of automatic video analysis technologies in video surveillance applications.

Active Smart Surveillance Architecture (ASSA):

Active Smart Surveillance Demonstration

Variable Message System (VMS)

Variable message signs can be placed in a wide range of places like highways, major road junctions, and urban arteries. Typically installed at the side or above the roadway, the VMS uses text and graphics in monochrome or color.

Traffic management systems are composed of multiple control and monitoring entities coupled by different communication facilities and protocols.
