Public transport in Damascus depends extensively on minibuses. There are about one hundred lines that operate inside the city and some of them extend from the city center to nearby suburbs. There is no schedule for the lines, and due to the limited number of official bus stops, buses will usually stop wherever a passenger needs to get on or off. The number of buses serving the same line is relatively high, which minimizes the waiting time. Lines are not numbered, rather they are given captions mostly indicating the two end points and possibly an important station along the line.
