Traffic Filter

Allows you to specify what types of traffic can travel on each lane of a road.

Example uses:
- Fake one-way roads.
- Roundabouts, cloverleafs, etc.
- Forcing transiting trucks to use a ring road.
- Truck-only lanes.
- Real bus lanes (and not bus-or-truck lanes).
- etc.

The filter comes in 4 flavors: for pre-1925 streets, pre-1925 country roads, post-1925 streets, post-1925 country roads[1]. All of them can be found in the street depot menu.

Each flavor has the following options:
- Street width: small, medium, large, or x-large (post-1925).
- Sidewalk: open or closed.
- For each lane: closed for everyone, open for everyone except trucks, open only for trucks, open for everyone.
- Other sidewalk: open or closed (for pedestrians).
- Tram line: no, unelectrified, or electrified (post-1875); compatible with street modification tool.

Known limitations and issues:
- There is no way to place a filter on an existing road -- you have to demolish the road first. Needless to say, this is a very big issue in cities.
- It doesn't provide Main Connection. You still need at least one normal road connecting the towns. This is for your own safety. The game tends to crash when there is a connection between two towns, but no way for cars to get from one to the other. If you promise to avoid such situations, you can use a mod like Majus's Fussgaengerzone to create fake Main Connections.
- You can't use it on bridges or in tunnels.
- It can't distinguish private cars from buses. This is a technical limitation and I don't know how to work around it (both buses and cars seem to use the BUS transport network layer). You can still use bus lanes on the surrounding roads though.
- It can't distinguish trams from buses. This is primarily due to very limited UI space. I had to sacrifice some options, and this one was the most useless.
- If you have buses and trucks on the same line, bad stuff can happen. Your vehicles might go in circles and never reach their destination. Or the game might crash.
- Vehicles really don't like to change lanes outside of intersections. There isn't much I can do about this, so you should just create intersections whereever you want them to switch lanes.
- If another mod adds cargo trams, cargo buses, or passenger trucks, you might get unexpected but consistent results.
- If another mod adds custom roads, they won't be automatically available in this mod. Feel free to extend this mod.
- If another mod increases the number of lanes in a stock road to >6 (or >4 pre-1925), those lanes won't be changable in the UI. To add more lanes to the UI change the corresponding numbers in the .con files of this mod.- If another mod modifies stock roads in other sane ways everything should be fine. Sane changes include number of lanes (as long as it's even and non-negative), road width, sidewalk width, sidewalk height, speed limit, name, description, price, and textures.
- If another mod modifies stock roads in insane ways (e.g. allows airplanes to walk on sidewalks)... I have no idea what'll happen, but WTF?!
- The models look ugly, especially in the first person view. PM me if you want to design better ones.
- Traffic filter is a stupid and misleading name. Please suggest a better one.

I get the same error as yours too. Yet another mod that appears to be borked. I've removed it from my list, until it's been sorted.
Also by looking at some of the comments on here there are other issues with it as well.

So I'll just stick to speed restrictions set by road type/size and use waypoints for my transport routes, and leave to traffic in general to do what it does.
