(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)
Documentation[view] [edit] [history] [purge]

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.

The template has three possible outputs to enable it to be used in documentation and guidance using less than, or greater than measurements. The default output is the minimum distance, the other outputs can be obtained using an unnamed parameter.


Parameters

|greater when placed in this template will provide an output which is 1 meter greater than the minimum length defined here.
|less when placed in this template will provide an output which is 1 meter less than the minimum length defined here.

When using these parameters to change to the output you may see an error when previewing the wiki page. However if you save the page the template is displayed properly.


Usage

Place {{:Routing_penalties/U-turn_minimum}} on any page where you want to display the following:

15 meters (49.21 feet)

Place {{:Routing_penalties/U-turn_minimum|greater}} anywhere you want to display a length 1 meter above the minimum (to include a safety buffer zone) to display the following:

16 meters (52.49 feet)

Place {{:Routing_penalties/U-turn_minimum|less}} anywhere you want to display a length 1 meter below the minimum (to include a safety buffer zone) to display the following:

14 meters (45.93 feet)
The above documentation is transcluded from Routing penalties/U-turn minimum/doc.
