  • Showcasing indigenous ITS solutionsand next generation Traffic Control Systems V.Muralidharan Associate Director, Head Control and Instrumentation Group Centre for Development of Advanced Computing Thiruvananthapuram (Society under Department of Information Technology, Ministry of Communications and Information Technology)
  • • Introduction• ITS products developed• ATCS implementation in Pune• Wireless Traffic Control System (WTCS)• Intelligent Parking Lot Management System (IPLMS)• Red Light Violation Detection System (RLVDS)
  • National Coverage C-DAC, Pune HQC-DAC, Bangalore C-DAC, DelhiC-DAC, Hyderabad C-DAC, Mumbai C-DAC, Chennai C-DAC, Kolkata C-DAC, Mohali C-DAC, NoidaC-DAC, Trivandrum 3000 employees
  • ITS products• Variable Messaging System (VMS)• Vehicle Tracking System (VTS)• Distress Call Response Management System (DCRMS)• Vehicle Actuated Traffic Signal Controllers (UTCS)• Area Traffic Control System (ATCS)• Wireless Traffic Control System (WTCS)• Intelligent Parking Lot Management System (IPLMS)• Red Light Violation Detection System (RLVDS)• Smart Tracking and Distress Alert System for Automobiles
  • Variable Messaging SystemDistress Call Response Management System Vehicle Tracking System
  • • 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
  • 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
  • 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
  • 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)
  • 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
  • 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
  • Traffic in developed countries Traffic in developing countries
  • Heterogeneous Traffic and Limited lane disciplineCannot apply classical method of signal time computationbecause of the complexities in deriving PCUs in real-time Requires special filters to address the situation
  • ATCS Software• Composite Signal Control Strategy (CoSiCoSt) – Developed by CDAC, DIT, Govt. of India – Address High Heterogeneity and Poor Lane discipline – Operates on VA Platform – Use Stop-line detection – Subtract Method for Online Signal Synchronization – Strategies to guard against network failure, power failure etc. – Indian Patent #239258
