Hey guys, here's something new: A patch pack with a certain theme.

I proudly present the Road Vehicle MiniPak. I've put some patches together, that all improve something regarding road vehicles.
The following patches are included (random order)

• Traffic lights
• Random road construction
• Pathfinder penalty for road vehicles
• Improved acceleration for road vehicles
• Speed limit for road vehicles

Hopefully these work fine together and create a new interesting gameplay with regards to road vehicles. Have fun!
Will also upload a win32 binary later.

Oh and...

Please don't.

you're fast

let's test this, going for a full road vehicle map...

now we need yet another patch: no speed limit on highways, even if in town

Good job, Roujin!

Great pak, great patches Roujin!

For me, the only road related patch left to wish for is the "handle one way roads as two lane roads"-patch, with vehicles really using the two lanes, not just for overtaking.

As promised, here's are the win32 binary files. Sorry for the delay.
Gedemon: post some nice screenies here, or even start a screenshot topic for it, will ya?

planetmaker: Yes, that's an issue The same goes for random road construction btw nothing worse than the town deciding to shut down my highway completely ^^ I've already thought about limiting road construction more, but that would need a lot of changing...

I'm doing my own test game atm and want to share some screens with you:
Here's a highway concept I came up with. It works because of the combination of
1) Pathfinder penalty for road vehicles
and
2) Speed limit for road vehicles
Namely the one-way bonus (or rather two-way malus) included in the latter. It causes vehicles to prefer the right lane, BUT: if it is busy, they will go on the middle lane, because of the first patch.
This is how it looks like normally: This is how it looks when there's more traffic: Nice, eh?
Maybe it would even cause nice overtaking effects, if there were more vehicles with different speeds. Have to test that...

Feel free to post screenshots of your RoadVehicleAwesomeness games

I'm very interested in feedback about vehicle movement at hills and curves using the improved acceleration patch, as these movement modes still need some testing and checking. I will follow this thread

Also, be aware that most NewGRF sets don't support the patch completely. The expected behaviour of an unsupported vehicle is to move at 1 km / h, but if they do something crazy tell me

Great patchpack, can you contact the maker of this thread and ask him to add your patchpack?

Cant help myself, but it would be useless, till that topic is not sticky or something it will be forgotten even quickier. Only few know about existance of that topic ...

I've played some years with this pak because I like to play with Road Vehicles. Didn't test all features yet but there are already two things that occured to me.
1 - see screenshot. There's a discrepancy between max. t.k. shown in the purchase window and vehicle window
2 - see savegame. In a few moments, a queue will occur on a slope after which some trucks crawl to a halt and drive uo the slope with 1 km/h. At this moment, this probably isn't intended behavior .

The vehicle shown in the vehicle window is loaded, and that increments its tractive effort. The tractive effort will be the same if you check both windows when the vehicle is empty.

The GRF set you are using has missing or incorrect acceleration values for some vehicles. The intended behaviour when the used acceleration values set speed to zero is to use a speed of 1 km/h instead. Since the Improved acceleration for road vehicles is just a patch, there is currently not much GRF sets that have ALL of their road vehicles working correctly. I know that some articulated vehicles in HEQS have this problem when loaded in slopes, and in eGRTVS there is also some vehicles that will not move at all. Since setting these values correctly in sets with so many vehicles is not an easy task, you should stick to supported vehicle sets (which to my knowledge are only standard vehicles and the hover bus) or disable improved acceleration and use the rest of the patches.

Aha, somehow I thought eGRVTS and HEQS were already compatible. Didn't know about the tractive effort (physics class is long ago ) but doesn't sound that weird in hindsight.

One other thing I noticed today which might or might not be a bug: I tried to make a one-way street of a town-owned road. This wasn't possible, the error message said something in the vein of 'road belongs to ..... . Weird thing is, that ..... is not the name of the town itself (town A) but another town (town B)! And in town C, the same error message is given with the name of town B. When using the info-tool on the tile, the correct owner is shown.

The fact that you cannot make town owned roads one way is intended and in vanilla trunk. The error message displaying another town may well be a bug, please try if you can reproduce it in an unmodified nightly of OpenTTD and if so, report it on Flyspray.

(Dies)
That aside but, If I had Improved RV acceleration version 6, could I safely upgrade to this? I'm asking because I had Improved RV acceleration 5 and upgraded it to Version 6 and my saves still worked.

Comm Cody: All versions of the Improved acceleration for road vehicles patch should be savegame compatible between them. Once that you bring your savegame to this patchpack you will be unable to use your savegames in any binary without all of these patches, though.

Okay thanks Terkhen.

HEQS is partially-compatible with the improved acceleration patch.
Non-articulated vehicles should work well.
Articulated vehicles need some values changing - some of them will crawl at 1mph on hills I'll get to that at some point.
