Traffic isn't fully random. Rush hour peaks happen about the same time etc. Handling that is an infrastructure and priority question. Given the political will one can build bus lanes and equip buses with a radio system which enables priority on traffic lights. In my hometown (Munich, Germany) this works quite well and most buses see mostly green lights.
