I rebuilt most of standard SCS' interchanges in Hungary and modify highways to real number of lanes (example, bridge over Danube now has 4+4 lanes).
Also, I enabled entrace in Budapest in all 4 directions. I know that new entraces aren't realistic, but it is better than nothing.
Promods is required.

Load order:
High traffic
Rudi's Rush hour
Improved semaphore cycles
Zoom
Less ferries
Longer brightness
EAA transmission
(you can permute them)
Promods def
Better traffic flow for Project Balkans
Project Balkans files
Rebuilt Hungarian interchanges
Better traffic flow for Rusmap (contains Realistic Russian highways Promods version)
Better traffic flow for Promods
Deleted Europe (without above maps, except Rusmap)
Better traffic flow for Southern region
Better traffic flow for Russian open spaces
Better traffic flow for EAA
Better traffic flow for ROC
Better traffic flow for PRC
Then original mods.

Note: Currently I don't have compatible version of ASSETS, so, if you want semaphores on highway crossroads, use:
Promods def
Promods assets
Promods model 1
Promods model 2
Promods model 3
