Bus lines with line spacing enabled and without bus end stations are intended to slow down to 30km/h to achieve interval between buses.

I have Bus traveling from Bus station to bus station and all buses are only traveling at 30. I have not had this issue before the last update
Note. I do agree that buses returning to station to pick up workers would slow down to keep spacing. But now its only 30kph to both stations pick up and drop off destinations

it sound wird its all your savegames/maps that are effected, that could sound like
something broke in the update. Maybe try and revert the update to the previous version and see if that help.
But if you have allot of busses on a line then they will behave as the player above write.
Maybe try and send a few busses to a depot to see if that help something.

( and just in case you are using roadsigns.. check there is not a roadsign that say 30kmt on the road being used or other signs that can slow down things. Sometimes people can get unlucky and place a sign that effect and entire city or all roads. )

I agree and would like to revert back the update to see if that is the issue or not. I just not sure on how to make that happen

do you have advanced trafic enabled?

perhaps you placed a 30km/h zone sign some place by mistake?

melkij is right - line spacing enabling does this, especially with more then 3 vehicles on a line. Use endstations instead to mitigate for this, that´s why they were introduced.

Problem with line spacing is that whenever a bus gets delayed/slowed down, the next bus in the line slows down up to 30 km/h to keep the time distance. With multiple crossroads and even moderate traffic, this will happen multiple times per each day. The more buses you have, the longer this domino effect lasts (third bus slowing for second one, ...). And then you have refueling. And maintenance. And shorting a trip due to lack of workers to get out in next "unload only" stops.

This all combined (especially the crossroads and refueling part) results in almost constant common crawl of 30 km/h for the whole line.

Endstation solves this both as it only cares about departure interval and what happens in the meantime, happens. And it refuels vehicles while waiting as well. The only thing you need to know is people CANNOT PLAN THEIR ROUTES THROUGH ENDSTATIONS, so if you have one per line, place it on the return trip from industries before picking up workers in the city again. And give it power (and fuel DO) so it can refuel ;)

Hi all, Advanced Traffic is enabled, no signs placed. I understand what your all putting down, I guess I just don't understand why I didn't have this issue before or I just didn't notice it before. I will try the other bus station and see if that works. Without line spacing buses are just bunching up badly Thanks!

Just a friendly note - such a fact that you have line spacing enabled should be mentioned in the main post to avoid people going off-topic debating other possible causes.
Line spacing can make buses go 30 km/h at any point of the route, not just before picking up passengers. However devs say that line spacing is obsolete and we should use end stations instead.

It's always fair to assume first and foremost that whatever issue you're having was caused by you at some point. Or as we say in IT - the problem is somewhere between the chair and the computer.

If you have for example 4 buses, and line spacing activated, if a bus goes for refueling, the rest of the buses will slow down.... if a bus goes into a traffic jam, the rest of the buses will slow down, to keep the distance

Also if you have dirt roads, every time a single bus of that line enters the dirt road, the rest of the buses will go to 30km/h

While end bus stations are the way to go, if you are poor, as my republic was at the beginning of the game, you can see slowing the buses to 30km /h .... as a feature, because they consume less fuel, and they serve the main goal... keep production buildings always populated and bus stations efficiency... obviously if the line goes very far, slowing down to 30km/h may make your workers teleport to the city before reaching the destination

Not true, road vehicles have a fixed fuel consumption rate. Current speed or weight has no effect.

i have a 5,3km long line with lane spacing, no end station, 5 buses, 2 stops in total, asphalt roads, 100km/h buses.
It usually takes about 2,5 hours traveling time to get from bus stop to another.

Winter is a little different, but that's because the snowplowing system sucks... Devs need to add an option where we can give roads priority for plowing.
That way we could give snowplows the order to prioritize plowing bus line roads over side road which aren't being used by anything...

There is a road sign "no snowplow". This sign can also be used to separate the working area of ​​snowplows from different tech services. For example, put an office with good snowplows in the middle of the highway, put "no snowplow" signs on the exits in both directions. In the city and in the industrial zone, put separate technical service offices. Now snowplows from the city or industrial zone do not go to clean the highway, the office on the highway deals only with its area.

which cannot be placed everywhere.

I'm far from been an expert, but afaik, the vehicle acceleration is a thing, you can notice that easier in the trains as they consume a lot of fuel before getting to max speed, if your vehicles have perfect traffic, and zero stops, fuel would be the same, but if your vehicles have to go from 0 to 100 instead of 0 to 30, fuel usage would be higher

with no end stations, there will be always moments where bus slow downs to 30km/h be aware of that, if at 100km/h they take 2,5h, at 30km/h they would need ~8h, so they will teleport.

You can't achieve solid stable speed with regular line spacing, there are always slowing factors

The fuel consumption mechanics had a few reworks over the years, at some point it was more accurate but it produced weird resutls and was hadrd to balance so it was brought back to quite simplistic looking method that produces quite sensible results.

Road vehicles burn fuel at a rate of 16.8* 18.5 days per fuel tank when they are in motion, aaaand thats about it. So if it drives over mud road or snow it consumes more fuel per distance because it travels slower. Same with acceleration, weak vehicle that needs to accelerate a lot will take more time so it will burn more fuel.

Trains etc have their own mechanics.
