Why do buses drive one after another and arrive at stops at the same time?

We try to stagger the intervals of lines that share stops so that they are spread out as evenly as possible. 

Lines running in different directions will arrive at schools, big workplaces or the city centre at similar times, especially during the times when people are commuting to work or to school, as most people want to get to these places at the same time. This also makes it possible for people to catch planned exchange connections, but it may lead to overlaps at shared stops.

Timetables are designed to meet passengers’ needs. When we plan timetables, we have to take into account the lengths and intervals of different lines and the targeted cost-effectiveness. Another challenge is the impact of other traffic and weather conditions.
