Ludwigstraße: Despite the narrow square, not feasible!
In the past few days, an event has caused a sensation to upgrade the non -existent theater district in Augsburg. On September 13, it was discussed how the urban landscape can be upgraded by creative measures. It was particularly about Ludwigstrasse, which is considered a typical neighborhood road. This street, which extends over 200 meters, has dense buildings and mixed use.
A central topic was the idea of planting additional rows of trees on Ludwigstrasse. The Altaugsburg company advocates this and asks the question of whether the room is sufficient. But here there is an important restriction. Ludwigstraße has a width of around 12 meters and can therefore not meet the requirements of the "guidelines for the creation of city roads" (RAST 2006). These regulate that two different cross-sections are required for neighborhood roads without public transport: 12 meters without trees and 15.5 meters with trees. Since the Ludwigstrasse is too narrow, the idea with the rows of trees is rejected.
The importance of the rest for urban planners
According to the guidelines, a distinction is made between two road types: main traffic streets (HS streets), which often offer local connections and allow speeds of up to 50 km/h, and access roads (ES-Straßen), which are primarily responsible for residential and work areas and usually have a speed of 30 km/h. In Augsburg, Ludwigstraße could at best act as an ES-Straße, but building construction and traffic safety take the street for trees. The high clearance profiles must be kept free of obstacles - this also includes trees that could be dangerous due to their height and width. An example illustrates this: a 7 meter high tree with a diameter of 4.50 meters would grow into the facades of the adjacent buildings and disturb the traffic noise.
What do the guidelines say?
The "Guidelines for the City States' system (RAST 2006) were published by the Research Society for Road and Transport and are introduced not only in Bavaria, but also in other federal states such as Berlin and North Rhine-Westphalia. These guidelines are divided into seven sections that cover different aspects of the road design, including the technical requirements for the street space and the integration of green areas. The current edition shows which standards are valid and which recommendations apply to planning.
It remains exciting to see how the city of Augsburg is concerned with the challenges of urban development and whether alternative concepts for natural greening can be found in narrow streets. Because despite the difficulties, Ludwigstrasse offers great potential for innovative solutions.
