Atren saying my material is not published and highly unreliable is not harassment Incidentally my opinions about PRT have been published Here s one from the Seattle Post Intelligencer I should also add that Professor Vukan Vuchic wrote the following in his book Transportation for Livable Cities Rutgers 1999 Personal Rapid Transit PRT is claimed by its promoters J Edward Anderson President of Taxi 2000 Corporation and Jerry Schneider of the University of Washington among others to combine the advantages of rapid Transit private cars Actually this is an imaginary system based on an operationally and economically infeasible concept elaborate infrastructure yet low capacity and has no realistic potential for application in urban transportation A decade later and PRT still hasn t entered into revenue service not in Masdar NY Times not in Winona Winona Daily News not in Daventry Daventry Express not in Minneapolis and not in dozens of other places Those are the facts Good luck
