From the Paved State

Back to the Garden State

Mobility without Highways for

New Jersey Alain L. Kornhauser

Professor, Operations Research & Financial EngineeringDirector, Transportation Research Program

Princeton University


Background• I’ve been dabbling in PRT for over 35 years• In many ways, I’m very disappointed in our lack of

progress:– A long time ago: Exec. Director of APTA said:

“Alain: PRT is the transportation system of the future…And Always will be!!!”

• But we have made progress:– Morgantown has proven that it can be done– APMs are a standard of every modern airport– Automation and computer controls have become ubiquitous,

reliable and cheap– There is broad movement towards energy independence and

alternatives to the petroleum economy


So…

• Premise:– NJ in 2009 is very different from NJ in 1909

• A look at what might be NJ’s Mobility in 2109(or before)


So…1889

PRT as the Dominant Mode.

What would it take?


PRT as the Dominant Mode. What would it take?

• Had my undergrad Transportation Systems Analysis class (Orf 467) looking at this for each of the past 3 years

• Def. “Dominant Mode”: Serve >90% of all intra NJ trips + access to existing mass transit serving NYC and Phila

• Def. “Serve”: Less than 5 minute walk to a station; stations all interconnected; all existing rail mass transit connected/


Sketch Planning Process• Precisely geolocate all trip ends by purpose

• Extensive use Google Earth and Msft. Virtual Earth to provide spatial reality perspective to trip end concentrations and Physical constraints

• Manually locate all stations and interconnection

• Analytically assign the trip end demand to stations and flow the trips on the interconnected network.

• Manually iterate the location of stations and interconnection

Bottom Line

Element Value

PRT Trips per day (90%) 26.51M

Peak hour trips (15%) 3.98M

Fleet size 530K

Fleet Cost $B $53B @ $100K/vehicle

Stations 11,295

Station Cost $28B @ $2M/Station

Guideway 12,265 miles

Guideway Cost $61B @ $5M/mile

Total Capital Cost $143B


Conclusions• It’s a lot• It does a lot• It’s one design focused on existing land use / mobility

patterns• We should be able to do better
