6. Closing Words<br />
6.1 Retrospection<br />
This work dealt with the topic of roundabouts in the focus, specifically randabouts as a traffic<br />
planning instrument from a landscape architectual point of view. The fundamental motivation<br />
for this study was a discourse which led to the remark that while roundabouts have<br />
recieved a lot of traffic planning euphoria in the last decade, landscape architectual design<br />
benefits have not recieved the same amount of positive feedback. At this point in time the<br />
majority of these areas are still not designed to satisfaction.<br />
According to this remark several questions evolved which went beyond the boundaries of<br />
landsacape architecture. Essential questions like: „What is the definition of the term roundabout?“;<br />
„Which types of roundabouts can be distinguished?“; and more specific questions<br />
such as: „What is a location/ non-location?“, and „How can roundabouts be easier/ better<br />
organized in the future?“. To answer these questions it was essential to undertake a multidisciplined<br />
analysis.<br />
The primary question was how to treat the topic in a way that considers all discplines together<br />
in one piece of work.<br />
Based on this objective, a classification was made which seperated the work into three thematic<br />
parts: traffic planning, sociological considerations, and landscape architectural aspects.<br />
To meet this objective literature reviews, inquiries to persons or bodys in charge of traffic<br />
planning, evaluations of photo databases, and on-site reviews of roundabouts were used to<br />
do a complete and comprehensive assessment.<br />
6.2 Findings<br />
First of all, it is to be held that all planned processing steps have been carried out successfully.<br />
The only exception ist that the initial objective of the typology key could not be realised<br />
sensibly and therefore, was adapted over the course of the work.<br />
The focus of the second chapter was on traffic planning aspects, more specifically to reduce<br />
the complicated and extensive process of intersection design into a substantially more clear<br />
and simple process. Especially for the characteristic of the intersection type roundabout,<br />
definition, design and decision steps were developed which provide quick on demand access<br />
to the desired information. Finalizing the chapter, a legal framework for accessible center<br />
islands of roundabouts has been presented and interpreted for the first time. This includes a<br />
comprehensive overview and discussion of possible crossing facilities for the opening of the<br />
central islands.<br />
The focus of the third chapter was on the sociological aspects of roundabouts, most specifically<br />
the sociological considerations of the movement and perception by individuals of a<br />
roundabout. This chapter successfull addresses the central issues: „How do individuals<br />
move in a roundabout?“ and “Roundabout - location or non-location? “; and “ Wh people<br />
use certain spaces and avoid others?<br />
The focus of the fourth and most comprehensive chapter is the landscape architectural aspects<br />
of roundabouts. It begins with a brief overview about the assignment methods for the<br />
