Intelligent Transportation Systems: Automated Highways, Autonomous Vehicles & Personal Rapid Transit By Alain L. Kornhauser Professor, Operations Research & Financial Engineering Director, Transportation Program Faculty Advisor, PAVE (Princeton Autonomous Vehicle Engineering) Princeton University October 11, 2010 CS 402 Intelligent Transportation Systems • Coined by Fed DoT in early ‘90s to include: – ATMS (Adv. Transp. Management Systems) • Intelligent Traffic Control Systems and Value Pricing Systems – ATIS ( EZ Pass mid 80s) (Adv. Transp. Information Systems) • Turn-by-Turn GPS Route Guidance Systems (‘97 CoPilot Live) – AHS (Automated Highway Systems) (R.Fenton ‘62 OSU, Sarnoff mid 60s) • Autonomous vehicles – ATS (Automated Transit Systems) • Personal Rapid Transit (Ficter ‘68, W. Alden ’71, – ARTS (Adv. Rural Transp. Systems) • Need something for the rest of the country CS 402 WWU ‘75 ) Intelligence (aka Automation) in the current Automobile • MICROPROCESSORS ECU- controls engine functions F1 video – • Cruise Control Module- Regulates speed while in cruise control – • • • • • • • • • CS 402 1st spark timing module in ‘77 Olds Toronado Intelligent Cruise control (1st into: Toyota ‘97; 1st US ‘00 Lexus) ABS Module- controls anti-lock brakes and may handle the traction-control and stability-control systems (1st ‘71 Imperial; 1st 4 wheel electronic: MB ’78) Traction Control (1st ‘71 Buick) Airbag Module- controls airbag deployment Body Controller- controls interior lights, door locks, windows, seats, etc Driver's Door Module- communicates commands from switches on drivers door to the body controller Climate Control Module- Monitors interior temperature and controls the heating and cooling systems Transmission Controller- controls automatic transmission Power Distribution Box Module- controls relays in the power distribution box Instrument Panel- Controls gauges, and indicator lights using data from the communications bus Intelligence (aka Automation) in the current Automobile • • Self-parking systems video (1st version Toyota ’03; US ‘06) Lane Departure Warning Systems – • AutoVue LDWS; Iteris YouTube 1 Frontal Impact Warning Systems Volvo video What’s Next: Lateral & Longitudinal Control • • CS 402 Transit: • Personal Rapid Transit (Network of autonomous vehicles providing non-stop Origin2Destination service) Consumer: • Automated Highways and Autonomous Vehicles Basically: • Problem is “simple” – Feasible region is a flat plane with boundaries. • “Challenge” is to properly identify the boundaries. • Longitudinal and Lateral control problems: – CS 402 Have velocity vector be Tangent to a centerline between feasible lateral boundaries • Focus on Automated Control Systems – for Automated Transit Systems (Personal Rapid Transit) • extensive research on control and management systems for large fleets of vehicles • area-wide network design for large-scale implementations – state-wide PRT – for Automated Highways • participation in DARAP Autonomous Vehicle Challenges – focus on stereo vision-based systems for local environment sensing » dynamic depth mapping, object identification and tracking, road edge identification. – robust control in the presence of substantial uncertainty and noise CS 402 • PRT (Personal Rapid Transit) • Fundamental Elements: – Off-line stations Morgantown 1975 Video1 Video2 • • Boarding, Alighting process does not impede bypass flows Average speed ~ Top Speed; Top speed need not be high – Guideway is Passive wrt Branching • Video Headway limited only by collision avoidance – with other vehicles not guideway branching mechanism » 1 sec headway possible – Vehicles need not be large • • Demand is very spatially and temporally distributed even during peaks Fleet having capacities varying between 3-6 passengers. – New Jersey State-Wide System • Designed by ORF 467 F04/5 – F10/11 + again this year • Objective: 95% O/D within 5 minute walk Taxi2000 Early 70s Orly Airport Laser-range headway control; 30cm separation CS 402 PRT@LHR Sept. 2010 Battery powered ULTra System CS 402 Off-line station with 2 berths Video Video Recharging “Shoe” Vehicles are battery powered; recharged in stations Central Control Room 2 cameras in each vehicle as well as everywhere else Bath, UK Delhi, India PRT in Masdar City, Abu Dhabi Video PRT in Masdar City, Abu Dhabi YouTube From: the Paved State Back to: the Garden State Mobility without Highways for New Jersey CS 402 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 CS 402 So… • Premise: – NJ in 2010 is very different from NJ in 1910 • A look at what might be NJ’s Mobility in 2110 (or before) CS 402 Looking Back • let’s look at the automobile: Daimler, 1888 • In the beginning, it takes a while CS 402 Central Ave. Caldwell NJ c. 1908 CS 402 CS 402 Bloomfield Ave. & Academy Rd. c. 1908 Before it was paved CS 402 Muddy Bloomfield Ave. c. 1908 CS 402 Muddy Main St. (Rt. 38) Locke, NY. c. 1907 CS 402 September 16, Finally: Automobile Congestion 1968 - present CS 402 September 16, Starting to Look Forward Daimler, 1888 Morgantown, 1973 CS 402 So… 1888 1973 CS 402 1908 1988 2073 http://orfe.princeton.edu/~alaink/PRT_Of467F07/PRT_NJ_Orf467F07_FinalReport.pdf CS 402 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/ CS 402 Middlesex County CS 402 Sussex County CS 402 Union County CS 402 Number of Stations by County & Main Trip End County Transp School Home Recre Office Industry Public Shop Religious MultiUse Other TOTAL Atlantic - 17 - 1 18 114 8 - 3 30 - 191 Bergen 28 217 394 47 81 37 15 32 17 249 - 1,117 Burlington 1 69 24 52 188 76 40 54 2 85 6 597 Cape May 11 30 173 46 17 217 38 18 47 351 28 976 2 37 106 7 68 86 24 27 2 78 - 437 18 30 102 237 9 9 15 92 - 83 - 595 Gloucester 2 103 192 9 20 9 3 13 6 55 - 412 Hudson 7 37 58 154 12 15 7 113 - 64 - 467 Hunterdon 2 39 107 26 21 34 25 44 9 78 20 405 Mercer 5 85 43 18 89 22 21 28 7 89 6 413 Middlesex 11 15 224 16 15 88 - 2 - 70 3 444 Monmouth 31 25 75 27 62 6 8 10 19 66 6 335 Morris 14 125 408 55 50 12 16 16 20 127 15 858 Ocean 11 105 55 60 76 69 52 56 - 42 14 540 Passaic 38 152 285 110 104 65 38 57 71 262 3 1,185 Salem 4 26 45 5 73 27 13 24 1 67 - 285 Somerset 7 39 330 19 31 10 2 23 6 94 7 568 Sussex 3 56 74 68 51 41 16 38 4 37 21 409 Union 16 48 99 112 91 26 45 57 - 83 - 577 Warren 11 42 217 45 55 32 28 20 1 22 11 484 TOALS 222 1,297 3,011 1,114 1,131 995 414 724 215 2,032 140 11,295 Cumberland Essex CS 402 November 30, 2010 County Stations Atlantic 191 Bergen 1,117 Burlington 597 Camden 482 Cape May 976 Cumberland 437 Essex 595 Gloucester 412 Hudson 467 Hunterdon 405 Mercer 413 CS 402 Miles 526 878 488 355 497 1,009 295 435 122 483 403 County Stations Middlesex 444 Monmouth 335 Morris 858 Ocean 540 Passaic 1185 Salem 285 Somerset 568 Sussex 409 Union 577 Warren 484 Total 11,295 November 30, 2010 Miles 679 565 694 1,166 1,360 772 433 764 254 437 12,261 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 CS 402 November 30, 2010 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 CS 402 Automated Highways CS 402 2005 Link to Presentation Not Easy Old House 2007 2005 2007 The DARPA Grand Challenges Defense Advanced Research Projects Agency • DARPA Grand Challenge Created in response to a Congressional and DoD mandate: a field test intended to accelerate research and development in autonomous ground vehicles that will help save American lives on the battlefield.
