Real Traffic Density by Cip v1.37.c
-reduced density on merging into motorways, exits and weigh stations
there should be much less queuing traffic in these areas.
if your game crashes at loading this means you have been doing it all wrong this time and had always another mod which changed silently the traffic density in your game.
my traffic mod is a tiny mod changing strictly only density related files and should be always at the very top of your mod list. it will not interfere with any other mod and your game receive the correct density.
