Since the 1960’s as planning and community design decision making has become increasingly contentious, the American legal system’s adversial approach to conflict resolution has become the dominant model for public decision making. The legal system’s adversial approach to adjudication is essentially a zero-sum game of winners and losers, and as most land-use lawyers will agree, is not a good model for the design of cities. While the adversial approach does not resolve disputes it rarely creates a positive and constructive consensus for change. Because physical planning and community design issues are not only value based, community design through consensus building has emerged as a new paradigm for physical planning and design.

The Environmental Simulation Center employs a broad range of complementary simulation and visualization techniques including 3-D vector based computer models, endoscopy, and verifiable digital photomontages to provide objective and verifiable information for projects and regulations under study.

In this context, a number of recent projects will be discussed which have explored the use of various simulation and visualization techniques in community design. Among them are projects involved with changes in the City’s Zoning Regulations, the community design of a major public open space in one of the region’s mid-size cities, and the design of a new village center for a suburban community, with the last project employing the Center’s userfriendly and interactive 3-D computer kit of parts. The kit - a kind of computer “pattern book” is comprised of site planning, urban and landscape design and architectural conventions - is part of the Center’s continuing effort to support a consensus based, rather than adversial based, public planning and design process.

Its potential regarding urban functionality, however, shows a drastic incongruity as far as aesthetic-atmospheric reality is concerned. Instead of representing a meeting point and the focus for the integration of city quarters in terms of visitors communication it has become cut off from is surroundings in the south and north by large traffic routes. Down-town Essen has become unattractive for the public and thus is avoided rather than visited.

An improvement of the Essen down-town area will only be effective if this incongruity is done away with. Therefore, the five-storey system train station is to be connected to the down-town and southern part of Essen on the three major levels level with the vicinity in such a manner that the requirements of its service-function as to representing a point of attraction, animating center and efficient connector are met. Our conception is aimed at turning the Central Train Station into an interesting welcoming- and farewell-place enticing dwelling and appealing business activities: the gateway of Essen and into the world.
