This file will change how agents handle arriving and leaving buildings it lets all agents to cross over to the other side to enter or exit a Building.   This makes it so that a car will cross over the center line or divider to enter or leave a building which in turn lowers the amount of u turns happening they will still u-turn if needed at the end of the road but it is much less likely they will do so because they passed their destination or started off in the wrong direction       unpack and place in your "..\SimCity\SimCityData\" the files for the roads you want the mod to affect there is one file for all of them
