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
• ParkShuttle Minibus
• ULTra Personal Rapid Transit
• CyberCab PRT/Microbus
www.autoroadvehicles.com 4
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
www.autoroadvehicles.com 5
ULTra Personal Rapid Transit Vehicle
• Scheduled to begin service at Heathrow airport, London in 2008
• Four passengers
• 25 mph (40 kph)
• Battery powered
www.autoroadvehicles.com 6
CyberCab PRT/Microbus
• Designed by same company that developed the ParkShuttle
• 6 passengers
• 25 mph (32 kph)

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
• 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
• 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

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
• 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

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