Subject of the main patent .... <> (patent application
W 30 331 V / I9c) is a road crossing for accident-free flowing vehicle and! Pedestrian traffic
which is formed by islands or boundaries for each direction of travel a lane of minimum width.

In the actual intersection area, these lanes are limited to a width that is not much larger than the maximum width of the largest vehicles, ie
for example 2.5 to 3.5 Et * While at a normal road intersection the actual area to be created has a width that corresponds to the width of the road, it decreases at the intersection after the main paten; this intersection area on a square with the side dimensions in the width of the crossing lanes. This means that a vehicle that needs about 5 to 8 seconds at a normal intersection to pass the entire intersection area, at an intersection according to the main patent the much smaller intersection area for the respective door traffic in a corresponding to the width ratio of the street width from 20 to 30 m to the width of the lane from 2.5 to ^y j, 5 m less time. As a result, even at a vehicle speed of 15 km per

At the crossroads according to Fig. Λ , double lanes 1, 2 or 3, 4 or 5, 6 or 7 * 8 lead into the crossroads, of which one lane 1, 3, 5 and 7 is provided for traffic turning right, while the other lane, 2, 4, 6 or 8 runs across the middle of the intersection to the opposite street. In the middle of the intersection, the lanes 2, 4, 6 and 8 are arranged at such a distance from one another that a ring lane 9 can be arranged within the area formed by the lanes. Each of the four lanes 2, 4, 6 and 8 is tangent to this ring lane 9.

For a vehicle that is approaching the intersection in lane 2, for example, and wants to turn left, This results in a first crossing period when passing lane 8 and a second crossing period when passing the lane 6. According to the basic principle of the invention of the main patent, every vehicle has during the first crossing period the right of way, while in the second crossing period the right of way of the others Must pay attention to the lane.

The intersection arrangement of FIG. 2 is essentially a hatred intersection according to FIG. 1.

At the intersection according to FIG. 3, double lanes 10, 11; 12, 13 and 14, I5 into the intersection. While the outer lanes 10, 12 and 14 for right-turn or straight-ahead traffic

are provided, the inner lanes 11 and 13 are used for left-turn traffic *

For the vehicle turning to the left, there are again two crossing periods, with the vehicle in the the first crossing period has the gate travel and in the two the right of way in the other lane for the tenth crossing period must pay attention to. The lanes 11 and 13 for the left turn rrerkehr are two-way in one gentle arc over the middle of the stimulation to the other Led away from the street.
