About time and connection lines. I think the busses in my city should be more corelate with trains - especially in the morningm where a lot of people use train. It would be also nice, when busses going next schools have schedule according to finish hours of students.
People also could participate in some survey giving information when and where they taking bus. Base on it busses could drive more often or be longer where and when they needed and the rest courses can go smaller busses, which are less using petrol and lee polute air.
