ABSTRACT
For quite some time now, traffic on the Grorungen Southern Ring Road (ZRG) has been experiencing considerable disruption. The ring road built in the 1960s had been intended to exclusively accommodate city traffic. In 1990, the Dutch government defined the Second Transport Structure Plan. This document contains the policies by means of which the government wishes to alleviate problems caused by increasing traffic until 2010. The policy is aimed at reducing the expected problems of car traffic growth until 2010. Stated in the simplest words, the ZRG issue is the very same problem faced by other cities with traffic congestion: too many vehicles traveling the same, too narrow stretch of motorway in too short of a time. Another possibility would be to try and spread the rush hour traffic over a more extended time slice. The problem of the road's narrowness could be solved by adjusting the existing infrastructure or by creating a new infrastructure.
