Transport route bundling
Under traffic routes bundling (also route bundle ) is defined as the principle, the paths of multiple (different) traffic routes to perform in a narrow space adjacent. The main advantage is that when building new traffic routes, landscape fragmentation is avoided compared to separate lines.
Deviations from bundling
If route parameters such as curve radius or gradient of the two traffic routes differ too much from one another or if there is limited space, this can make bundling in individual route sections impossible. As a result, the traffic routes run on separate routes here. In this case, the more inflexible or subsequently added traffic route must switch to a mostly more cost-intensive alternative route, which can also include complex tunnel or bridge construction .
Such as the connection of a lying off the bundled Route - Similarly, traffic engineering reasons can transport hub - lead to a deviation from the traffic routes bundling.
Examples
Most traffic route bundling is implemented in such a way that another route is added as close as possible to an existing route.
In Germany, planned new railway lines since the 1990s have often been run parallel to existing motorway routes in large parts.
To a greater extent, this concept was first in the construction of high-speed line Cologne-Rhine / Main implemented, it runs to 133 kilometers (another source: 140 km) parallel to the highway A3 . The new Nuremberg-Ingolstadt line follows the A 9 in the same way for around 54 km . The high-speed route Mannheim – Stuttgart was also largely bundled with existing traffic routes in the Rhine Valley between Mannheim and Wiesental .
The new Erfurt – Leipzig / Halle line runs parallel to Federal Motorway 14 for a length of 13 km , the high-speed line Nuremberg – Erfurt partially (23 km) parallel to Federal Motorway 71 and the new Stuttgart – Wendlingen and Wendlingen – Ulm lines for 22 and 23 km respectively parallel to Federal motorway 8 . A 20 km bundling with the new and upgraded Karlsruhe – Basel line is planned along the federal motorway 5 . The new Rhine / Main – Rhine / Neckar line is also to run parallel to the 67 and 5 federal motorways .
In France, LGV Nord was bundled with motorways in the section between Paris and Lille over a length of 135 km (41%). The LGV Sud-Est , between Paris and Lyon , has such a bundling over a length of 60 km (14%). In Belgium, the high-speed line was HSL 3 by highway A3 between Liege and Aachen bundled.
Transport route bundling is not only used for motorized modes of transport. It is also used for the nature and environmentally friendly management of hiking trails in large protected areas. One example is the new Goetheweg on the Brocken in the Harz Mountains . With German reunification in 1990 and the accessibility of the Brocken again, the number of visitors to the mountain increased rapidly. Therefore, the historic hiking trail off the railway line, which ran over the Hirschhorn cliffs and directly up to the Brocken, was not repaired. Instead, a new path was laid parallel to the Brocken Railway . This bundling made it possible to minimize the effects on the highly sensitive nature in the core zone of the Harz National Park .
