This mod is part of former Better traffic flow. It is mostly designed for players who like high traffic and for players who don’t like current semaphore cycles. However, high traffic causes traffic jams and slower traffic flow. In order to speed up the traffic flow, I changed work of semaphores: mostly longer green lights, partially solved problem of left turn (right turn in UK), removed red-yellow light and allocated those seconds to green light. Use only one of 2 files.
