b) Build AUTOSHUTTLE and reduce Motorway to 4 Lanes instead
AUTOSHUTTLE
instead of enlarging motorway, motorway reduced to 4 lanes. First AUTOSHUTTLE
will be built without intermediate stations. Annoyance during construction
equals the annoyances during an extension to 8 lanes. After reduction of
traffic volume on the motorway took place due to AUTOSHUTTLE
the intermediate stations will be built successively. In its final state
the motorway has 4 lanes.

I.e. 90% of the area of alternative a). The stations could be built on “lost” surfaces between ramps and motorway. The “effective” space consumption can become as low as 82% then, as the example of the A3 connection Leverkusen shows.
