Motorway ringroad A99 Munich - Relocation of the junction Aschheim / Ismaning, Bavaria, Germany

, 2016

Challenge

Due to the extension of the junction Aschheim / Ismaning on the motorway A99 near Munich, it was necessary to adapt the according signposts, display points with hard shoulder running as well as the corresponding video components. The concerned section of the traffic management system includes three lanes each in both driving directions plus hard shoulder, which was supposed to be used as temporary additional lane even during the construction works.

Details

In the course of the project, the signposts of the junction Asch­heim / Ismaning were dismantled and newly installed at the relocated position.

The display points of the corridor control system were adapted to the changed requirements. Thus, in cooperation with the traffic management center, also the release sequences for the hard shoulder running system had to be adapted accordingly. Additionally, the video points had to be adjusted to the new locations and visibility conditions.
