(To allow the U-turn prevention mechanism to kick in, the median crossover segment in a box U-turn must be less than:)
15 meters (49.21 feet)
This template is used to display the minimum distance required to allow two left turns, or two right turns to generate a U-turn in a route. This template enables this number to be changed if necessary over time without having to change the individual pages.
 |
Other conditions will also contribute to u-turn allowance or prevention. For more information see preventing medial u-turns. |
The template has two possible outputs to display the minimum distance required to enable a u-turn and the maximum distance to disable a u-turn. The default output is the minimum distance to enable a u-turn.
Parameters
When the template is used with |less, |below, or |disable, the output will be the distance below the threshold and therefore the maximum distance that will disable a u-turn.
When the template is used without any parameter (or any other undefined parameter), the output will be the minimum distance above the threshold that will allow a u-turn.
Usage
Place {{[[::Routing_penalties/U-turn_minimum|:Routing_penalties/U-turn_minimum]]}} on any page where you want to display the minimum segment length to allow a u-turn:
15 meters (49.21 feet)
Place {{[[::Routing_penalties/U-turn_minimum|:Routing_penalties/U-turn_minimum]]|less}} (or one of the other parameters listed above) anywhere you want to display the maximum length of a segment that will disable a u-turn.
Expression error: Unexpected < operator. meters (Expression error: Unexpected < operator. feet)
The gap in the two thresholds is due to metric and imperial rounding issues, so a buffer was built into this setting to prevent unexpected results. For more information on this issue, see WME segment length display.
