Inner bus lanes not being used?

And bus lane paths problem I forgot to say, if your road with bus lane, and the bus lane is not outside lane (for example the bus lane inside), the bus don't go first with it and even if never go with bus lane.

Not tested this yet. Just gathering some roads to test with:

• inner bus lane
• 'middle(ish)' bus lane
• both inner and outer bus lanes!
• one way car + bus (with bus essentially on inner lane)
• inverted direction inner bus lanes

Also, I note the Busses may ignore lane arrows setting on Policies tab in mod options. IMO this option should be enabled by default as it solves this major issue: https://tmpe.viathinksoft.com/wiki/index.php?title=Busses_may_ignore_lane_arrows (which could be related to https://github.com/krzychu124/Cities-Skylines-Traffic-Manager-President-Edition/issues/10#issuecomment-459995320 ?)

Yup, I think it's good idea to enable it by default.

BTW you can make checklist with markdown :wink:

• [ ] test - [ ] test
• [x] test - [x] test

I've subscribed the bus roads and will try and test them over next couple of days.

This could possibly be related to #34 (bugged road asset) but I'm not sure. Either way, bus route should never cut through a median like this.

EDIT: This problem is caused by wrong value for NetInfo.m_CanCrossLane in the road asset itself. I have added it to the list of broken road assets.

After much testing of the specific issue in OP (busses not using inner bus lanes) I have found the following:

• This seems to primarily affect the first segment at a junction (see image below)
• If I put a bus stop in the fist segment bus lane, it works fine
• If the route is longer, the bus will enter the segment via outer lane (so it's not crossing too many lanes of traffic I assume) and only at subsequent node head towards the inner bus lane
• When it does head towards inner bus lane, it cuts across 2 lanes!!

Note that this road doesn't suffer from the "drive through median" issue like the road in the previous comment. This is due to NetInfo.m_CanCrossLane settings.

Note that the size of the incoming road doesn't affect the path finding; here a 3 lane road connects to the bus road:

I also tried using lane connector to ensure that the outer lane of incoming road could was connected to the bus road, and it made no difference.

The Busses may ignore lane arrows setting in Policies and Restrictions did not make a difference in this case; it wasn't that the bus couldn't reach the inner bus lane, it was that it preferred the outer lane so as not to cut across too much traffic.

Thoughts...

When bus routing, at a junction:

• Normal road lanes get a penalty
• Bus lanes get a boost
• Bus can choose any lane of target road
  • ...other vehicle types should still follow normal rules and prefer outer lanes.
