One reason why you've got train jams because your intersections aren't far enough apart to take the full length of a single train. Hence, when they need to change tracks, they can't do it, and they just get backed up.
That's not true, if I remove the junctions it's still train after train after train. They are moving but there are to many of them for the crossings to open for traffic. ( which is why I've built tunnels or viaducts everywhere where possible except on deserted roads or where I lacked the space).
Impossible to tell from the one angle but I'm guessing you have another set of motorway exit/entrance slip roads just at the bottom of that screenshot?
If that is the case you need to space them out further. Or create a frontage road to collect local traffic and feed it onto the motorway using 1 entrance/exit slip road.
That is true, the motorway splits into 2 motorways, but still, this is idiotic, they don't need to be in the middle lane to go right, they should be able to go right from both the middle and right lane. There's no space to space them out further, if they had normal lane choices then there'd be no problem. Also it's a shame you can't widen motorways in advance of junctions, by that I mean an extra lane for the ''exit'' or an extra 2 or 3 lanes for something splitting off eg. :
You are correct that I should have build a local/express setup from the beginning like this :
Problem is, in the game it seems to take up more space than IRL, the scale between buildings and roads is a bit off too imho.
You can achieve this in a limited way by enacting the Highrise Ban over a district so it doesn't upgrade to the tallest buildings.
Thanks, I'll try that for aesthetics, shame the contrast population wise ( and with it traffic) is still messed up though!
Are most of those trains nearly empty? Have you not separated your local train network from the regional train network? This is a must in cities with more then 1 train station.
Nope I haven't, this is ridiculous though, this doesn't happen IRL, I live near a busy railway myself with both local and regional traffic and stations every 2-3 miles or so, during the day there's a train every 5 minutes for both directions, you don't see train traffic jams though.
Trains are often around half full to full in my game.
I miss wider (level) junctions, a 2x3 road crossing a 2x3 road, should have at least 6 lanes at the junctions ( eg. 2 lanes left 2 lanes straight 2 lanes right) with also individual traffic lights for each turn ( preferably more customization with lanes, and traffic light timings, to give dominant traffic flows more green time and more lanes).
And the lane choice of the ai in general is appalling, I mean yes there are loads of dumb drivers IRL, but not so dumb, you won't see a traffic jam on just the middle lane, because further on the motorway splits into two. ( if anything the right 2 lanes or all 3 should be jammed up).
Also the ''keep to the right'' ( or left in the UK's case) doesn't seem to be existent, moving over to the left lanes only to overtake, give space to joining cars or in congestion.
I know I'm way to demanding, but I'd love a far better traffic simulation. ( even though that is probably way to complex for a game, especially on this scale).
