摘要

The highway comprises three lanes (1a,1b,1c) separated by green strips, the central lane being relatively wide, whilst those on opposite sides of it are relatively narrow. A motorist must always use two lanes. Between the lanes strips (5a,5b) are installed, which are hard with grass concrete blocks. After some time, these blocks can become green. The central lane has a width of 1 meter to 1.7 meters. The side lanes each have a width of 1 to 1.4 meters. The green strips preferably have a width of 0.5 to 0.7 meters, so that the total width of the highway is approximately 5 meters. The road is particularly installed in an outer area. The green strips have an open structure, preferably of concrete or stone. A part of the road in a length direction is divided into segments, which have a length of 50 to 200 meters.
