Layout of 2+1-Routes in Germany - New Findings

The aim of the presented dissertation (Irzik, 2009) was to determine an optimal length for two-lane sections within 2+1-routes in dependence on various parameters. A correlation between traffic volume and share of incomplete dissolving processes has been used in order to define the necessary length of a two-lane section. A maximum length – depending on traffic volume and share of heavy goods vehicles – is also suggested. This restriction shall prevent that the length of a two-lane section and with it the length of the one-lane section of the opposite direction will increase excessively. Otherwise negative effects on platooning would have to be expected. Finally a minimum length according to traffic safety is recommended for two-lane sections within 2+1-routes. This recommendation is based on the relation between the share of vehicles changing from the passing to the right lane on the last 200 m of a two-lane section related to the total number of all passing processes and the number of observed conflicts while lane changing on the last 200 m. The overall result of the presented dissertation is a simplified method for determining the optimal length of two-lane sections within 2+1- routes.
