    1. Zars Cars that form Trains Bruce McHenry Founder RoadTrains.us

    2. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Transportation Requirements Eliminate Accidents Eliminate Congestion Make Public Vehicles Desirable Reduce Oil Insecurity Reduce Stress

    3. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us More Vehicles => More Crashes

    4. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us At Maximum Throughput, Highways are Mostly Empty 111 needed for 16 car at max throughput (50 MPH with 1.3 sec following)

    5. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Most Time Lost in Heavy Traffic Occurs on City Streets

    6. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Mass Transit Hardly Used in the US Takes twice as long Plus many other hassles

    7. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Re

    8. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Zars Hitch electric cars to form trains Combustion engines for locomotives

    9. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Hybrid-Electric Train Locomotive assisted by all-electric follower cars: - at low speeds (engine off) - during rapid acceleration - to climb hills Highway cruising locomotive engines operate nearer least fuel per HP-hr (60% of rated power)

    10. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Claimed Benefits Favorable collision dynamics Triples capacity of highways and intersections Inexpensive all-electric cars get unlimited range Up to 50% reduction in energy use Instead of driving work, play, sleep, etc. Provides a safe human driver at high speed/complexity for robocars (i.e. transit, taxis, car-sharing) Spurs electrification of arterial roads

    11. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Lead SUVs and Trucks Often Shield Followers

    12. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Active Steering Needed for Very Close Following Steering linked hitches provide failsafe redundancy

    13. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us

    14. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Hitching Doubles MPG Aerodynamic coupling can reduce highway speed drag by about 50% All electric followers have no engines and need only small batteries 40% reduction in weight 40% reduction rolling resistance Engine is either off (low speeds) or nearer max efficiency at 60% of max HP

    15. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Reduces Wanton Stress Can talk on the phone, surf the net, sleep, watch the kids, etc.

    16. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Benefits

    17. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Hitching allows all-electric cars to have unlimited range and small batteries Benefits

    18. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Feasibility / Hurdles Requires fail-safe longitudinal & lateral controls New collision dynamics require redesign of frame and cab Deployment / utilization of DSRC and WiMax Attaining critical mass (chicken & egg problem)

    19. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Next Steps Build community of designers, engineers and supporters (RoadTrains.us) Create prize awarding foundation to stimulate the development of open technology, especially interfaces (Bruce.McHenry@KeyPrize.org)

    20. BIL 2009 Long Beach, CA Bruce A. McHenry RoadTrains.us Thank you.
