  • I promised only 10 differences. The eleventh, replacing fuel taxes, will become important soon, as a significant portion of vehicles become all-electric.
  • A one-size fits all pricing system makes no sense in a world of
    Multiple vehicle types
    Multiple trip purposes
    Multiple geographies
    Multiple congestion circumstances

    RAT RUNNING: going on a nearby road or street to avoid a charge point.
  • It is also very flexible.
    We could change time of day
    …or the relative prices between main roads and city streets.
    We could make it free for you in your neighborhood, but not for me if I visited you.
    We could give tourists discounts – or not.
    We could have a different winter and summer scheme (just like the new electricity pricing scheme!)

    If you can think it, it can be done.
  • It is extensible, geographically at the flick of a geographic database, the management cost of tolling a country is barely more than tolling a city – relatively speaking.


    It is fairest if pricing is distributed smoothly - pay only for what you use.
  • 100% wireless systems leave your landscape uncluttered, undisturbed, unobstructed
  • This is one of the 18 or so gantries leading into and out of Stockholm for its successful congestion pricing program.
    You will need a lot of these for microwave systems … and what about tolling everywhere to replace fuel tax as we electrify the personal fleet?
  • It is possible to provide a full spectrum of privacy capabilities.
    On the left, you can be fully anonymous and pre-paid just as you can with a cell phone or with a 407 transponder (thanks to the PRIVACY-BY-DESIGN work of Ontario’s Privacy Commissioner, Dr Ann Cavoukian). Unfortunately, I was told there are only four or six customers, although it is a free 407 service option!)
    In the center, there are several ways to be private some with online storage available only to the driver, and some with driver-agreed access by (say) your insurance company.
    On the far right, it is possible to permit location data to be visible as is now used for commercial logistics or bus-information systems.
    These privacy choices can be locked in at initialization making it impossible to switch once the driver makes his choice.
  • You can start with a small area, or with one class of vehicles and grow

    The lack of fixed external infrastructure means some can stay with existing ways to pay

    You can design variable programs for families with children, trucks, service vehicles

    If it needs adjustment, that will be a database change

    1. 1. 10 Reasons GNSS Tolling Is Better Than Microwave Preet Khalsa, Chief Technical Officer Bern Grush, Chief Scientist 10th Slovenian Road and Transportation Congress Porteroz, Slovenia, 21-23 October 20101
    2. 2. GNSS Tolling  More flexible  More extensible  Lower transaction cost  Less environmental impact  Greater fairness  Greater privacy  Greater revenue potential  Evolutionary introduction  Traffic management  Interoperable  Fuel tax replacement 2
    3. 3. 1 More flexible Policy and Control  Any imaginable policy  Pricing rules  any time  any distance  any place  any cordon  any segment  any vehicle type  Manage exceptions  Avoid rat running  Supply-demand rules prevail 3
    4. 4. 4 GNSS road pricing system is FLEXIBLE…
    5. 5. 2 More extensible Infrastructure Free Buildout  Every new kilometer or square kilometer of GNSS extension is just a database change  Every new kilometer of microwave extension cost the same as the first kilometer 5
    6. 6. 6 A GNSS road pricing system is Extensible…
    7. 7. 3 Lower transaction cost  Infrastructure-free means incremental cost per transaction falls faster as system expand to fill a region/country  RUC transaction costs fall even faster as GNSS OBUs handle many more applications  Microwave suffers from diminishing returns as a network extends past limited access roads 7
    8. 8. 4 Less environmental impact No gantries No guard rails No power No barriers to avoid 8
    9. 9. 9
    10. 10. 5 Greater fairness Charges are fairer  Smoother distribution of charges  Vary by demand  Scaled to time of use, weight, emissions class “Paying proportional to use is fairer than relying on accidents of geography or route.” - From Overcoming Global Gridlock 10
    11. 11. 6 GREATER PRIVACY Only GNSS can be 100% private  Microwave records time at location  Cameras record time at location  Paying for gas tax with credit card records time at location  Smart GNSS clients offer full location anonymity  and personal audit 11
    12. 12. Smart Meter Privacy Spectrum It is possible set any level of privacy requested by customers 12
    13. 13. 7 Greater Revenue Potential  Net revenue increases as new toll lanes added  Sat-nav signals are non-proprietary and free, increasing OBU pricing competition  More applications: parking, insurance, safety, traveler services, etc  more revenue  Lower operating costs  Little or no roadside infrastructure  Increased competition 13
    14. 14. 8 Evolutionary Introduction 100% in-car infrastructure means  Start small & build (extensible)  Voluntary programming  Programs to fit purposes  Changeable/adaptable (flexible) 14
    15. 15. 9 Traffic Management Wide-area, traffic volume data:  Aggregated and anonymized  Managing traffic signals  Congestion-based navigation  Planning  Routing 15
    16. 16. 10 Interoperable Non-proprietary signals  Anyone can operate anywhere ISO Standards  Financial data exchanged at back-office Infrastructure-free  GNSS system can overlay (geo-fence) microwave system  Let microwave stay for now 16
    17. 17. 11 Fuel Tax Replacement Fuel Tax replacement is fair only if you can charge anywhere For the best traffic management system since the round-about…  Design FIRST for transport demand management  Design SECOND for traffic control  Design THIRD for tax collection 17
    18. 18. 10 Reasons GNSS Tolling Is Better Than Microwave THANK YOU 10th Slovenian Road and Transportation Congress Porteroz, Slovenia, 21-23 October 201018 More Flexible More Extensible Lower transaction cost Less environmental impact Greater Fairness Greater Privacy Greater Revenue potential Evolutionary Introduction Traffic management Interoperable Fuel tax replacement
