  1. Assessment of Intelligent Transport System Communication Requirements Version 1.0 Rajesh Kapoor, Director(Technical)-TCIL 26-27 September 2017 HOSTED BY

  2. Assessment of Intelligent Transport System Communication Requirements Version 1.0 • Index • Issues and Challenges of Transportation • Objective of ITS • Application in Transportation requiring communication services • Assessment of Data requirements for V2X communication • Desktop Assessment of Radio Network Deployment Requirements as per Harmonized frequency band (5.850-5.925 GHz) • Assumptions for Road network and Vehicle parameters • Assessment of Bandwidth and spectrum requirements • Assessment of short range communication distances

  3. Issues and Challenges of Transportation • Overcrowding and High Congestion on Roads • Causing Traffic Jams • increased travel time • Higher energy Consumption • Pollution • Vehicle Health causing traffic disruptions • Safety on roads • Parking Infrastructure • Emergency Services for Health & Policing • Violations of Traffic rules • Rash driving causing accidents • Road maintenance issues causing traffic disruptions • Mixed Traffic of Two wheelers, three wheelers, Four wheelers • Public Transportation Service Delays for passengers

  4. Objective of Intelligent Transport System • Address growing need of • Traffic Monitoring • Energy consumptions, • Safety on roads, • Pollution on road, • Overcrowded roads, • Sufficient parking infrastructure, • Reduce Travel time • Ease of travel in public transports etc. • Evolve a Communication Network to address the developing Transportation ICT based application requirements for optimized resource management of time, travel, energy beating congestions and socio-economic Development

  5. Applications of Transportation requiring Radio Communication Services • Electronic Toll Collection • Traffic Management • Parking Management • Transport Violation Communication & Penalty Management • Fleet Management System • Emergency and Special Vehicle Movement • Road Infrastructure maintenance & Management • Connected Vehicles System • Connected Infrastructure System • Travel Information System • Separate Detailed Study of the Application architectures for deployments as Public Information Infrastructures needed • Present scope has been limited to assessment of the communication network requirements for Road Transport Applications

  6. Data Requirements for V2X Communication shall be a few kbits per transaction

  7. WRC-15 recommended Candidate Spectrum for Harmonization for ITS Applications (between 5 150 MHz and 5 925 MHz)

  8. Assessment of Channel bandwidth and Communication Distances for Radio Network Deployment as per Harmonization requirements of WRC-15 At 5.850 - 5.925 GHz for Transportation

  9. Methodology for assessment of Spectrum and Communication Distances for Intelligent Transport system

  10. Methodology for assessment of Spectrum and Communication Distances (Worst Case scenario) • Road Intercrossing distance assumptions (500m) • No. of roads on a crossing assumption : maximum 10 roads • Type of Vehicles on Road assumptions • Type1: Car (3m); Type2: Police Van/ Ambulance(4m); Type3:Bus /Truck(14m); Type4: Large Truck (18m) • Assessment of number of Converging vehicles on 4 lane road Crossing (3200-800) • Data Rate for V2X communication (1 kbps) • Bandwidth Requirements for communication at a Crossing with av. 4 roads (5.12-1.28 MHz) • Total Bandwidth / Spectrum Requirements ( 20 – 5 MHz ) • Communication distance assessment ( in Meters ): • V2IV2V • Antenna Height 8m : 470-750 140 • Antenna Height 14m : 590-1150 to 240

  11. Assumptions for assessment of converging vehicles on a crossing

  12. Assessment of Bandwidth and Spectrum Requirements

  13. V2X Communication Range at 5.850 - 5.925 GHz The communication ranges, as shown in detail in subsequent slides, have been calculated in different topographical regions using SUI Model with Correction Factors Path Loss Propagation model This Model has been reported to produce most realistic pathloss results at this frequency band Based on the pathloss calculations used in this model, detailed link budget calculations have been made to calculate various communication ranges The Model is based on certain Assumptions / validity parameters as below:-

  14. V2X Communication Range at 5.850 - 5.925 GHz Considering System Link Margin of 15 dB Note - System margin of 15 dB kept in link design is expected to take care of the two cases of "Almost single hop".

  15. V2V Communication range at 5.850 - 5.925 GHz Considering System Link Margin of 15 dB Note - In case of V2V where value is not given, please refer Slide on SUI Model Assumptions

  16. Conclusion Range of Communication with System Link Margin 15 dB at 5.850 - 5.925 GHz Vehicle to Infrastructure (V2I) Communication Vehicle to Vehicle (V2V) Communication

  17. ConclusionRange of Communication with System Link Margin 15 dB at 5.850 - 5.925 GHz

  18. Conclusion Spectrum Requirements for Different Data Rates Maximum No. of incoming Vehicles per crossing for 500 M inter-crossing distance :3200
