|

unprotected left, unprotected right on red. Followed by a variable stage that has protected
|

left, unprotected right on red. With a last stage that is all-walk and variable.
|
||
In some degenerate cases, usually with one or more one-way, this can reduce to stage per road.
|
||
In some rare cases, usually with an alleyway, oncoming lanes can’t both be protected left turns.
|
||
In such cases the stage is split into two stages with each having a protected and yeild turn.</p>

First find roads that are straight across, they are either one-way or two-way.
|
||
For one-way, add any right or left turns, thus completing the stage. For two-way, two
|
||
stages will be added. The first stage has protected straight, and right and yield left.
|
||
The second stage has protected left. Lastly, sometimes oncomming left turns can’t both
|
||
be protected, if this occurs the 2nd stage will have one direction protected and the
|
||
other yeild and a 3rd, inverse, stage will be added which has the other direction’s left
|
||
protected and other yield. Finally, any turns which weren’t assigned, because there
|
||
are no straights or there are more than just pairs of straight intersections, are assigned a
|
||
stage. These, too are handled as pairs until one remains, which is handled as a one-way.</p>
