  • Congratulations... May please concetrate on further reduction of waitings at junctions to save gallons of fuel. Shorter time delays than existing shall be considered for switching the signals. This will help to save fuel, I guess. Time of the day, peak direction etc should be considered in real time.

  6. 6. • Implementation of Area Traffic Control Systems (ATCS) for heterogeneous and undisciplined traffic• Benefits of Wireless Traffic Control Systems (WTCS)• Advantages of multilevel Intelligent Parking Lot Management Systems (IPLMS)• Red Light Violation Detection System (RLVDS) challenges
  7. 7. Area Traffic Control System• Area traffic control systems are traffic responsive systems that use data from vehicle detectors and optimize traffic signal settings to reduce vehicle delays and stops• The system operates in a closed loop, evaluating the real time demand and properly updating network signal timings
  8. 8. Benefits of ATCS• Real-time control over traffic fluctuations• Better management of signal timings• Reduced stops and delay• Savings in fuel and reduced pollution• Data collection for planning and MIS• Higher availability• Reduced accident rate
  9. 9. Popular operational models– SCOOT – Split Cycle and Offset Optimization Technique– SCATS – Sydney Coordinated Adaptive Traffic System– OPAC – Optimization Policies for Adaptive Control– RHODES – Real-Time Hierarchical Optimized Distributed and Effective SystemOther systems– ACS-Lite (Adaptive Control Software Lite)– SPOT / UTOPIA (Urban Traffic Optimization by Integrated Automation)– MOTION (Method for the Optimization of Traffic Signals in On-line controlled Networks)– ITACA (Intelligent Adaptive Control Area)– RTACL (Real-time Traffic Adaptive Control Logic)– CoSiCoSt (Composite Signal Control Strategy)
  10. 10. Challenges are differentOperational Models Traffic characteristics in Problem(SCOOT , ITACA, ..) Developing CountriesAssume limited High heterogeneity and Results in wrong vehicleheterogeneity and lane limited lane discipline counts and volumefollowing estimationAssume no lane change Lane change happens Detectors fail to reportwithin the detection zone within and after detection turning proportions zoneUse Upstream detection Vehicle Actuation needs Cannot be on VA Platform stop-line detectionCoSiCoSt has special filters for addressing High Heterogeneity and poor lane discipline. It is built on VA Platform offering high scalability
  11. 11. Challenges in implementing ATCS onIndian roads• Traffic is not lane following• A vehicle entering the approach on a lane need not maintain the same at the intersection• High mix of traffic• Uncontrolled side roads and on-street parking• Obtaining a correct measure of traffic count is highly complex• Data loss due to power failure• Network failure
