new technology for small people movers
New Technology for Small People Movers
  • Electronics replace mechanical parts
  • Lateral control: steers like a car
  • On-board power supply, usually batteries
  • Guideway is just exclusive, light duty road
  • Often called Automated Road Vehicles
  • New technology may not always be best (wide guideway, snow removal issues)

examples of new technology vehicles
Examples of New Technology Vehicles
  • ParkShuttle Minibus
  • ULTra Personal Rapid Transit
  • CyberCab PRT/Microbus

parkshuttle minibus
ParkShuttle Minibus
  • Has carried the public on one-mile route near Rotterdam
  • 20-25 passengers
  • 20 mph (32 kph)
  • lead-acid batteries, recharges in off-peak

ultra personal rapid transit vehicle
ULTra Personal Rapid Transit Vehicle
  • Scheduled to begin service at Heathrow airport, London in 2008
  • Four passengers
  • 25 mph (40 kph)
  • Battery powered

cybercab prt microbus
CyberCab PRT/Microbus
  • Designed by same company that developed the ParkShuttle
  • 6 passengers
  • 25 mph (32 kph)

principles of operation
Principles of Operation
  • Shared service, not private
  • Minimum headway: 5-10 seconds
  • Maximum grade: 10 %
  • Low interior headroom means all seated, but acceleration and jerk limits set for standees
    • Wheelchairs not secured
    • Can’t be sure all passengers are seated

two way guideways
Two-Way Guideways
  • Other lane is emergency walkway
  • Two-way is not twice as expensive
  • Direct routes reduce vehicle miles
  • Easier to put two-way guideway at grade; must have grade separation to allow access to area within a one-way loop

End-of-Line Station

Vehicles back out of berths into turn-around area

guideway routing
Guideway Routing
  • Place guideways at grade whenever possible
  • Stations at grade eliminate elevator costs
  • Run guideways behind buildings, not in front
  • If possible, guideways should cross streets, not run along them

Layout of Feeder Systems for the Morgantown PRT
  • All are a single two-way line, no branches
  • Most have stations at end points only
  • One system also has a center platform station along the line

operating parameters
Operating Parameters

* Based on maximum speed of 25 mph (40 kph)

approximate unit capital costs
Approximate Unit Capital Costs
  • Two-way elevated guideway: $10M / mile, not strongly dependent on vehicle weight
  • Two-way at-grade: $1.5M - 3M / mile + land
  • 6-passenger vehicles: $150K - 200K
  • 20-passenger vehicles: $500K
  • Central control: $200K ? per system, but some savings if multiple systems

additional data needed for system costs
Additional Data Needed for System Costs
  • Unit capital costs for stations
  • Site specific construction costs
  • Unit operating costs for vehicles
  • Other O & M costs
  • Operating policy, for example maximum wait time in the off peak
  • Patronage

  • Student / Faculty / Staff mobility
  • Removing cars from streets improves traffic flow for alldrivers
  • Reduced need for expensive parking structures
  • Increased value of land near stations
