"Missile Vulnerability--What You Can't Know," Strategic Review, 10:2(1982). The paper reviews the many factors that will compromise the accuracy of ICBMs aimed at hardened missile silos and concludes with the paragraph: "The kinds and numbers of weapons available today would seem to make it impossible to develop a consistent and rational war-fighting strategy aimed at a political objective other than suicide. In such a circumstance the Department of Defense faces enormous difficulties in its search for technical solutions to the problems of national security. Alfred Nobel wished he could 'produce a substance or a machine of such frightful efficacy for wholesale devastation that wars should thereby become altogether impossible.' I believe that this machine is with us now."
"Calculation of Performance and Fleet Size in Transit Systems," JAT, 16:3(1982)231-252. This paper provides a consistent, analytic approach to the calculation of the parameters needed to analyze the performance and cost of transit systems of all types including network systems. The method developed is a fundamental improvement over the method developed in Section 4.3 of Transit Systems Theory.
"Nuclear War Fighting Means First Strike," ASEE Annual Conference Proceedings, 1983.
It is more than coincidence that weapons deemed necessary for a prolonged nuclear war are perfectly suited for a first strike. If any nation develops a first-strike potential, the security of the world is threatened because it provokes others to develop first-strike potential as well, and thus escalates the arms race. Consequently, current U. S. defense policy is itself a threat to genuine security because it increases the risk of nuclear confrontation. The solution must lie in a more complete definition of security that stresses cooperation among nations rather than strictly equating national security with military power.

"Optimization of Transit-System Characteristics," JAT, 18:1(1984):77-111. In this paper a system-significant equation for the cost per passenger-mile is developed and from it, using available data, it is shown that the system that minimizes cost per passenger-mile has all the characteristics of the true PRT concept.

"What Determines Transit Energy Use," JAT, 22:2(1988):108-132. In this paper the energy use of heavy rail, light rail, trolley bus, motor bus, van pool, dial-a-bus, auto, and PRT are compared. The energy required to overcome air drag, rolling resistance, and inertia; and the energy require for heating, ventilating, air conditioning, and construction are calculated. Calculation of these factors for the conventional transit systems is based on the averages given in federal data report "National Urban Mass Transportation Statistics"

"Dependability as a Measure of On-Time Performance of Personal Rapid Transit Systems," JAT, 26:3(1992):101-212. Dependability is defined in this paper as Person-Hours of Delay/Person-Hours of operation in a PRT system. Such a definition, while desired in conventional transit, cannot be measured without asking every patron the destination of his or her trip, which is impractical. The paper shows both how to calculate Dependability in advance of deployment of a PRT system and how to measure it while the system is in operation. The method provides the basis for precise contract language by which to measure on-time performance.

The model is fully three-dimensional.
"The Birth of a Breakthrough in Urban Transportation," Distinguished Alumnus Lecture, North Park College and Theological Seminary, Chicago, Illinois, March 1, 1994. The author was invited to speak at North Park College as the 1994 Distinguished Alumnus Lecturer on his role in the development of Personal Rapid Transit (PRT), the first genuinely new urban transportation system to appear in a century. This Chapel Lecture describes his relevant technical experience, his search for meaning, his need for interdisciplinary project work, and the extraordinary circumstances and timing that led him to PRT as a new career, and that carried this work to the point where it has been taken over by a major corporation and a major urban transportation authority. The lecture ends with a challenge to young people to aim high and seek a noble cause of fundamental importance to mankind.
"Safe Design of Personal Rapid Transit Systems," JAT, 28:1(1994):1-15. The safety of PRT systems involves careful attention to all features of the design such as the use of a hierarchy of fault-tolerant redundant control system, bi-stable fail-safe switching, back-up power supplies, vehicle and passenger protection, and attention to the interaction of people with the system. Safety, together with reliability and adequate capacity, must be achieved while making the system economically attractive; hence techniques to achieve these goals at minimum life-cycle cost are primary in PRT design. The paper describes the relevant features in a new transit system and the principles of safe design required to develop it.
"Seminar on Personal Rapid Transit," Chalmers University, Gothenburg, Sweden, June 6-16, 1995.
"Synchronous or Clear-Path Control in Personal Rapid Transit," JAT, 30:3(1996):1-3. This paper derives an equation for the ratio of the maximum possible station flow to average line flow in a PRT or dual-mode system using fully synchronous control. It is shown that such a system is impractical except in very small networks.

"Some Lessons from the History of PRT," Conference on PRT and Other Emerging Transportation Systems, Minneapolis, November 1996.
"Guideway Characteristics," Topics in the Design of PRT Systems, 1997. Guideways required to support and constrain moving vehicles are analyzed based on the results of dynamic analysis of vehicles moving on flexible spans. The analysis is applicable to systems in which small vehicles operate at a full range of speeds including speeds applicable to intercity travel. Specific results useful in the design of guideways of any cross sectional configuration are developed.
"Longitudinal Control of a Vehicle," JAT, 31:3(1997):237-247. Generally applicable formulae for the gain constants in a proportional plus integral controller required for stable control of the speed of any vehicle in terms of natural frequency, damping ratio, vehicle mass, and thruster time constant are derived. An example, based on a simulation of the controller and vehicle, is given. The theory shows that only speed and position feedback are needed. Acceleration feedback is unnecessary.
"Control of Personal Rapid Transit Systems," JAT, 32:1(1998). The problem of precise longitudinal control of vehicles so that they follow predetermined time-varying speeds and positions has been solved. To control vehicles to the required close headway of at least 0.5 sec, the control philosophy is different from but no less rigorous than that of railroad practice. The preferred control strategy is one that could be called an "asynchronous point follower." Such a strategy requires no clock synchronization, is flexible in all unusual conditions, permits the maximum possible throughput, requires a minimum of maneuvering and uses a minimum of software. Since wayside zone controllers have in their memory exactly the same maneuver equations as the on-board computers, accurate safety monitoring is practical. The paper discusses the functions of vehicle control; the control of station, merge, and diverge zones; and central control.
"Personal Rapid Transit: Matching Capacity to Demand," an Advanced Transit Association paper, February 1998. The paper gives a comprehensive discussion of the question of both required and obtainable capacity in PRT system based on both observation of the behavior of people and on theory. It is shown that once a network of PRT guideways is laid down rather than the few widely spaced lines of conventional rail system the required capacity of both lines and stations is remarkably modest, but that a modern PRT system will exceed the maximum practical throughput of most conventional rail systems.
"Effect of Redundancy on Failure Frequency in PRT Systems," Theory of New Transit Systems. In this paper the effect of redundancy on failure frequency is calculated in more detail than found in the author's 1978 textbook Transit System Theory.
"Simulation of the Operation of Personal Rapid Transit Systems." Computers in Railways VI, WIT Press, Boston, Southampton, 1998, 523-532. This paper describes a computer simulation program developed by the author to study the operation of personal rapid transit (PRT) systems of any size and configuration. The control scheme is asynchronous with maneuvers commanded by wayside zone controllers. The simulation runs on a PC, is accurate in every detail, and can be used to run an operational system, which would use dual-redundant computers on the vehicles, at wayside to manage specific zones, and in a central location to manage the flow of empty vehicles and to perform other system-wide functions. Some results are given.
"A Review of the State of the Art of Personal Rapid Transit." JAT, 34:1(2000). The paper begins with a review of the rational for development of personal rapid transit, the reasons it has taken so long to develop, and the process needed to develop it. Next the author shows how the PRT concept can be derived from a system-significant equation for life-cycle cost per passenger-mile as the system that minimizes this quantity. In the bulk of the paper the author discusses the state-of-the-art of a series of technical issues that had to be resolved during the development of an optimum PRT design. These include capacity, switching, the issue of hanging vs. supported vehicles, guideways, vehicles, control, station operations, system operations, reliability, availability, dependability, safety, the calculation of curved guideways, operational simulation, power and energy. The paper concludes with a listing of the implications for a city that deploys an optimized PRT system.

"Deflection and Twist of a Curved Beam under Uniform Load," Transit Systems Theory (2), November 2001. In this paper an exact equation is derived for the deflection of a curved beam clamped at the ends and subject to a uniform load. The method used was developed by S. Timoshenko based on strain-energy considerations.

We look forward to the day when universities will regularly teach courses on HCPRT design and planning and when a number of competent firms will be manufacturing HCPRT systems. HCPRT is close to moving to mainstream and can bring about a brighter future for mankind.
