3.3.5. Traffic conditions: examples

Traffic conditions must be set at intersections where additional information about road signs, traffic lights, or markings that define the specific driving rules for that intersection is needed to automatically set the route.

This section provides examples of road conditions:

Example 1. Right turn at intersection forbidden

Before the intersection, prescriptive signs are set that show the required directions of movement and at the same time prohibit right turns:



This situation is mapped by specifying the traffic (prohibition of right turn at the intersection):



Note. This example shows one of several traffic signs at a complicated intersection.

Example 2. Left turn at intersection forbidden

Before the intersection, prescriptive signs are set that show the required directions of movement and at the same time prohibit left turn:



This situation is mapped by specifying the traffic (prohibition of left turn at the intersection):



Example 3. U-turns forbidden

At this intersection, you can go straight or turn left, but you can not make a u-turn:



You can enter a traffic sign on the map to reflect this (see drawing): The maneuver includes two sections of the road after the intersection that the ban applies to (indicated by green arrows) - so that the permitted left turn is not prohibited:



Example 4. U-turns forbidden (permitted traffic directions indicated)

Before the intersection there is a sign prohibiting left turns, as well as prescriptive signs that show the required directions of movement and at the same time prohibit u-turn:



You can enter a traffic sign on the map to reflect this (see drawing):



Example 5. Forbidden turns at road forks and intersections with exit ramps

Example 5.1. Road fork

Perekopskaya St. forms exit ramps as it approaches the intersection, which is why u-turns are prohibited:



You can enter a traffic sign on the map to reflect this, as shown in the drawing. Here, u-turns are forbidden when the road splits to form exit lanes:



Note.

If this type of ban isn't set, when there is a traffic jam on the main road, the automatic router can set a route that includes prohibited driving.

Example 5.2

Three two-line roads intersect at a fork in the line:

This is mapped using the following road signs (red arrows mark the area where turns/u-turns are forbidden at intersections of central roads):

Example 5.3. Intersection of road with exit ramps

Intersection of road with exit ramps:

This is mapped using the following road signs (red arrows mark the area where turns are forbidden:

Example 5.4

Three one-line roads intersect at a fork in the line:

This is mapped using the following road signs (red arrows mark the area where turns are forbidden:

Example 6. Left turns forbidden when u-turns are allowed

At this intersection, you can make a u-turn, but you can not turn left (for commercial vehicles):



You can enter a traffic sign on the map to reflect this (see drawing): The attribute in the Applies to field places a turning restriction on freight transport. The maneuver includes two sections of the road after the intersection that the ban applies to (indicated by green arrows) so that the permitted u-turn is not prohibited:



Example 7. Legal u-turn at break in solid line

A permitted u-turn at the point where the solid markup is broken is set by the corresponding condition of movement.:

Example 8. Legal u-turn (not prohibited)

At the intersection of a road drawn using one line that has no signs forbidding u-turns, you should enter four “legal u-turn” road signs:

Note.

It is allowed to turn at all intersections, which is not prohibited a u-turn and turn left, and you do not specify the direction of movement of the bands, prohibiting the left turn and u-turn.

U-turns at intersections involving one-way streets may also be forbidden.

Example 9. Left turn forbidden for bicyclists in accordance with traffic laws

Bicyclists are forbidden from turning left and making u-turns on roads with tram lines in the middle of the road, and on roads that have more than one lane for traffic going in that direction.

That's why you must add a no left turn warning for bicyclists at intersections with a road containing a tram line.
