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 ( EZ Pass mid 80s)EZ Pass –ATIS (Adv. Transp. Information Systems) Turn-by-Turn GPS Route Guidance Systems (‘97 CoPilot Live)‘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, WWU ‘75 ) –ARTS (Adv. Rural Transp. Systems) Need something for the rest of the country

CS 402 Basically: Problem is “simple” –Feasible region is a flat plane with boundaries. “Challenge” is to properly identify the boundaries. Longitudinal and Lateral control problems: – Have velocity vector be Tangent to a centerline between feasible lateral boundaries
6
CS 402 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
7
PRT (Personal Rapid Transit) Fundamental Elements: –Off-line stations Boarding, Alighting process does not impede bypass flows Average speed ~ Top Speed; Top speed need not be high –Guideway is Passive wrt Branching 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 Morgantown 1975 Video1Video1 Video2Video2 Morgantown 1975 Video1Video1 Video2Video2 Taxi2000 Video

16
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
17
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)
18
CS 402 Looking Back In the beginning, it takes a while let’s look at the automobile: Daimler, 1888

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 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. The Grand Challenge brings together individuals and organizations from industry, the R&D community, government, the armed services, academia, students, backyard inventors, and automotive enthusiasts in the pursuit of a technological challenge. The First Grand Challenge: Across the Mojave, March 2004 Across the Mojave from Barstow, California to Primm, Nevada :$1 million prize. From the qualifying round at the California Speedway, 15 finalists emerged to attempt the Grand Challenge. The prize went unclaimed as no vehicles were able to complete more than 7.4 miles. The 2005 Grand Challenge Multi-step qualification process: Site Visits, NQE – Semifinals, GC final event 132 miles through the Nevada desert. Course supplied as list of GPS waypoints. October 8, 2005 in the desert near Primm, NV. Prize $2 million. The 2007 Urban Challenge Nov. 2007; 60 miles in an urban environment. Lane keeping, passing, stop-signs, K-turns “driving down Nassau Street”. Range of Prizes

I could see from the electronics textbook they were using that they were learning as they went.”
