Though I have not experienced this problem during my school days or college days, I have seen several of my friends running after the buses for getting into it. During those days only very limited number of buses were on road (remember I studied during 1955 - 1966).I had the opportunity to stay almost near schools or colleges. But my friends used to talk about their difficulties in catching buses. They reach the bus stops sufficiently early so that even if one bus was missed they expected the next buses to pick them.
In bus stops near schools here in Cochin, I notice police people are posted to stop the buses and allow the students to get in. Of course, all students will not be allowed to enter same bus but they divide them and share among buses. Such system has been found be useful.
