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
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
