Cycleways and travelators

Odd thoughts about high speed travelators/moving walkways. Architects like Brian Rogers had a big thing about them in the 60's. If you want a high capacity (bodies per second) line then a travelator is the thing for you. In the 70's Dunlop tried to invent versions that could slow down and speed up but they could never deal with the problem of people 'bunching up' and then collding as they slowed down. I was told my David Turner ( guy at Warwick University that had done a lot of simulations of this ) that you have problems with the little old lady not walking way from them. 


So what happens if you have one designed for cyclists only ? I saw a cyclist level change in Holland ( nice ) and thought about it as a ski-lift like gradient change device. 


At this point you don't need moving handrails and if you come off you just coast ( assuming there is nothing either side to collide with). More importantly once you come off you just coast (so no little old lady slow moving blockage ). This would be true if you had a system that accelerated too and if the system broke then the passengers would not be threatened. 


Something to consider. What would happen as you got on ( front wheel on back wheel off) if the break was off I guess your front wheel might go backwards for a second.
