Updated for Airports DLC update. Lane connection algorithm improvements for even better traffic flow!

Fixed: Crash when connecting two identically oriented roads (e.g. Vanilla Overpass Project + Road Anarchy).

Improved bus lane handling.

Updated to use Harmony 2.0.4.

Changed lane connection rules for sharp turns

Dedicated turning lanes are no longer created (with some exceptions), if the angle between two joining roads is <50.1°.

This allows a two-way road to be split into two parallel one-way roads without creating "U-turn lanes".

Fixed: Lane connections often incorrectly assigned to symmetrical one-way roads, mainly in left-hand traffic.
Fixed: A number of minor bugs affecting lane assignment in some relatively rare cases.

Fixed: Shared car-tram/trolley/etc. lanes ignored during lane assignment.

Fixed: Cycle paths were participating in lane assignment.
Fixed: Crash on roads where two vehicle lanes in the same direction share the same position (probably very rare).
