  2. 2. ((ITS)) ITS is the system defined as the electronics, advanced technology,communications or information processing used singly or integrated toenhance safety, mobility, and the economic vitality of the surfacetransportation system. The Intelligent Transport Systems (ITS) makesautomobiles and the road traffic infrastructure intellectual and information-oriented in an integrated way to provide a safe and comfortable trafficsystem. Intelligent Transport Systems (ITS) include telematics and all types ofcommunications in vehicles, between vehicles (e.g. car-to-car), andbetween vehicles and fixed locations (e.g. car-to-infrastructure). However,ITS are not restricted to Road Transport - they also include the use ofinformation and communication technologies (ICT) for rail, water and airtransport, including navigation systems. In general, the various types of ITS rely on radio services forcommunication and use specialized technologies.
  3. 3. ITS Goals and ObjectivesThis section addresses the goals and objectives for ITS inkajang. The goals refer to ultimate outcomes that arecoordinated with state wide goals of the transportationsystems. The objectives represent specific deliverables fromthe ITS planning process.Setting goals for ITS follows the general areas outlined inthe national ITS program. Those goal areas include:1. Traveller safety2. Traveller mobility3. Transportation system efficiency4. Productivity of transportation providers5.Conservation of energy and protection of the environment.
  4. 4. ITS Plan ObjectivesThe main objectives of the plan include the following:1. Develop an ITS vision and strategic direction for kajang.2.

  8. 8. PROBLEM STATEMENTTraffic congestion is a road condition characterizedby slower speeds, longer trip times, and increasedqueuing. It occurs when roadway demand isgreater than its capacity. A period of extremetraffic congestion is colloquially known as a trafficjam.
  9. 9. PROPOSE AND OPTIMIZE TRAFFIC CONTROLAT JALAN RekoThe proposed ITS bid for Jalan Reko comprises a KajangIntelligent TransportSystem Control Centre.A new transport control centre would be the focus for trafficsignals, network management and passenger transport operationsin the pilot area facilitating the following improvements:• Integration of systems• Expansion of existing systems• Development of new systems and services
  10. 10. The development of the proposal is still at an early stage, but specific areasthat are being considered for inclusion include improved the coordination ofall network management areas will help to carry out the highway authorityby the Traffic Management, for example, enabling a quicker response toincidents on the network, thereby reducing delays to both car travellers andpublic transport users alike.This will include improving the way the following systems work together:• Traffic signals• Improved coordination of road works, special events• New car park information signs• New traffic information message signs• CCTV cameras• Travel information (including real time bus passenger information,incidentson the network, etc)• Out of hours cover and emergency response to highways incidents
  11. 11. ITS ARCHITECTUREThe National ITS Architecture provides a commonframework for planning, defining and integrating intelligenttransportation systems. It was developed through broadparticipation fromtransportation practitioners, systems engineers, systemdevelopers, technology specialists, consultants, etc. over thelast ten years. The architecture defines:I. The functions that are required for ITS (i.e., collection oftraffic information)II.The physical entities or subsystems where these functionsreside (i.e., the roadside or the vehicle)III.The information flows and data flows that connect thesefunctions and physical subsystems together into an integratedsystem.
  12. 12. Linking ITS to the Transport Planning ProcessITS needs to be integrated into the local or regionaltransportation plan. An ITS architecture supports thisintegration by forcing all involved to identify theintended relationship between ITS and conventionaltransportation plans and solutions. It can also addsubstance to those plans through the definition of what isrequired to provide which services and the priority fortheir implementation.
  13. 13. Traffic Control systemDesigning, implementing, optimizing and adjusting urbantraffic control systems involves quite some effort andknowledge. Due to several reasons, changing environments notalways lead to changes in the traffic control units. Adjusting atraffic control unit is a costly and timely affair. Suffolk County Accessible Transportation (SCAT)Split, Cycle and Offset Optimization Technique (SCOOT)Intelligent Traffic Adaptive Control Area (ITACA)Blind Spot System (BLISS)Signal Operations Analysis Package (SOAP)Max bandRondo
  14. 14. Smart Surveillance systemArchitectures:there are three different types of smart surveillancearchitectures .The outputs of video cameras are recorded digitally andsimultaneously analyzed by the smart surveillance server,which produces real time alerts and a rich video index.The types and parameters of the alerts are user configurable.
  15. 15. Architectures of smart surveillancesystem
  16. 16. Active Smart Surveillance Architecture (ASSA): The uses:1.Face Cataloguer: This is a system which aims to non-intrusivelyacquire a high-resolution face images of all people passing througha space, Here ASSA detects and tracks people and uses the activecameras to zoom in and acquire high resolution face pictures.2.2. Multi-scale Video: This is a system which automaticallyallocates higher resolution to portions of the scene which havecertain predetermined types of activity. For example, all cars thatare moving with high speed through a parking lot may be imagedat a higher resolution through the active cameras
  17. 17. A Traffic Monitoring System• Traffic signal light can be optimized using vehicle flow statistics obtained bySmart Video Surveillance Software (SVSS). At present, one of the biggestproblems in the main city in any country is the traffic jam during office hourand office break hour. Sometimes it can be seen that the traffic signal greenlight is still ON even though there is no vehicle coming. Similarly, it is alsoobserved that long queues of vehicles are waiting even though the road isempty due to traffic signal light selection without proper investigation onvehicle flow. This can be handled by adjusting the vehicle passing timeimplementing by our developed SVSS.
  18. 18. Vehicle detection techniquesModel based detectionRegion based detectionActive contour based detectionFeature based detection
  19. 19. Vehicle Detection with WirelessSensors• Traffic detection is a fundamental component of the planningand operation of local roads and highways in California. Whileinstalling and maintaining the inductive loop detectors that aretraditionally used to detect traffic can be expensive, a uniquenew technology called the Sensys wireless vehicle detectionsystem (VDS) is proving to lower the lifecycle costs associatedwith detecting traffic.
  20. 20. CommunicationIntelligent Transportation Systems vary in technologies applied,from basic management systems such as car navigation, trafficsignal control systems, variable message signs or speed camerasto monitoring applications such as security CCTV systems, andthen to more advanced applications which integrate live dataand feedback from a number of other sources, such as ParkingGuidance and Information systems, weather information, bridgede-icing systems, and the like. Additionally, predictivetechniques are being developed, to allow advanced modellingand comparison with historical baseline data.
  21. 21. kinds of Communication• Wireless Communication• Computational Technologies• Floating Car Data (FCD)• Sensing Technologies• Inductive Loop Detection• Video Vehicle Detection• Short range communications are used for less than 500 yards.

  23. 23. Sensing Technologies• Sensing technologies have greatly enhanced thetechnical capabilities and safety benefits of IntelligentTransportation Systems around the world. Thesesensors include inductive loops that can sense thevehicles speed, the number of vehicles passing aswell as the size of these vehicles
  24. 24. Video Vehicle DetectionMost video detection systems require some initialconfiguration to teach, processor the baselinebackground image. This usually involves inputtingknown measurements such as the distance betweenlane lines or the height of the camera above theroadway. The typical output from a video detectionsystem is lane-by-lane vehicle speeds, counts and laneoccupancy readings. Some systems provide additionaloutputs including gap, headway, stopped-vehicledetection and wrong-way vehicle alarms.
  25. 25. Variable massage system (VMS)• is an electronic traffic sign often used on roadways togive travelers information about special events. Suchsigns warn of traffic congestion, accidents, incidents,roadwork zones, or speed limits on a specific highwaysegment. In urban areas, VMS are used within parkingguidance and information systems to guide drivers toavailable car parking spaces.
  26. 26. kinds of VMS• Portable variable-message signs• Radar speed sign
