4. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.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 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Most Time Lost in Heavy Traffic Occurs on City Streets
6. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Mass Transit Hardly Used in the US Takes twice as long
Plus many other hassles
7. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Re
8. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Zars Hitch electric cars to form trains
Combustion engines for locomotives
9. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.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 2009Long Beach, CA Bruce A. McHenryRoadTrains.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 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Lead SUVs and Trucks Often Shield Followers
12. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Active Steering Needed for Very Close Following Steering linked hitches provide failsafe redundancy
13. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.us
14. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.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 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Reduces Wanton Stress Can talk on the phone, surf the net, sleep, watch the kids, etc.
16. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Benefits
17. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.us Hitching allows all-electric cars to have unlimited range and small batteries Benefits
18. BIL 2009Long Beach, CA Bruce A. McHenryRoadTrains.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 2009Long Beach, CA Bruce A. McHenryRoadTrains.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)
