Westinghouse Transportation Division(WTD) has incorporated microprocessor control into several previous Automatic Train Control (ATC) designs for both mass transit and people mover systems. It has become necessary to reexamine the rationales of previous designs in order to synthesize an optimal design solution for the more stringent quantitative requirements of new-generation systems. A design methodology has been applied which integrates functional, reliability, maintainability, and safety requirements at a stage sufficiently early to allow them to be adequately addressed.

Design procedures for cellular mobile telephone systems have emphasized the evolutionary nature of systems in capacity, features and service area. As time has passed since the first cellular system description in 1968, the design procedure itself has undergone evolutionary changes. Early analyses were conducted with idealized layouts to examine re-use patterns and expansion methods. These design exercises generally had no reference to actual limitations. Little or no field data was available to verify modeling as realistic. Introduction of design parameters such as varying cell sizes, better estimates of actual user density needs and considerable field data from the Motorola and AMPS activities have all contributed to new standards and guidelines for design in a more realistic form.

During the second century of electric and hybrid vehicles, these may again become a large percentage of the automobile population, due to the projected depletion of fossil petroleum. Other proposed energy sources for propulsion are yet to be proven economical or adequate. Electricity is cheap and abundant. Three electrical technologies represent challenges to make an EV acceptable; better batteries, lower cost power semiconductors, and microprocessors for logic control. A network of electrical outlets for charging batteries of EVs when the vehicles are not in use will hasten the acceptability of EVs. Until the "better battery" is developed, the hybrid car can provide the "performance" and reduce petroleum dependence.

Several driver information and traffic monitoring systems have been investigated in the past: CACS in Japan and ALI in Germany. Future systems must be designed modular: The finest step is an autonomous navigation system; the second, step includes some fairly cheap infrastructure with steady-state information transmitted to cars; the third step makes this information dynamic, i.e. traffic-dependent. VOLKSWAGEN and SIEMENS have built demonstrating equipment in Wolfsburg.

An optimization approach is used to design a velocity-adaptive, lateral controller to meet requirements pertaining to lateral-position tracking accuracy, robustness, and ride comfort. The resulting nonlinear controller required full-state feedback and thus an observer, which was nonlinear with velocity, was included. The observer/controller compensator was implemented using a 16-bit microcomputer and evaluated in a laboratory study wherein vehicle lateral dynamics were simulated on an analog computer. Excellent lateral control -- close tracking |lateral-position error| < 0.024 m in curve tracking), a good insensitivity to disturbance forces and probable ride comfort -- resulted. The selected control algorithm was realized using some 5% of the available computation time. Thus the microcomputer could also be employed for other control functions and vital-function monitoring.

In 1981, planning was initiated for an expansion to the AIRTRANS system at the Dallas/Fort Worth (DFW) Airport. In order to prevent disruption to existing AIRTRANS services, detailed planning was necessary to ensure a coordinated construction project. Specific program participant assignments were established using a matrix format which identified specific program tasks and a breakdown of AIRTRANS expansion elements. A specific guideway construction sequence was established to permit continuous AIRTRANS operations through the construction site.
