Georges Perec- The Street- the bus route

Why do the buses go from this place to that? Who chooses the routes and by what criteria? -p.52-

A bus passes through the main street. The route is chosen by the popular sites, such as downtown, big market, or another station. Sometimes the flow of traffic determines the route as well. For instance, the bus waits when it has ample amount of time before reaching the next stop, but if it's in hurry, it can even pass a less popular designated stop. Bus drivers skip the whole street sometimes. Then the waiters increase and they stay longer on the street. By the next bus reaches the stop, it is already filled with postponed bus riders who were 13 minutes behind their schedule. The buses are categorized by the riders' professions and time too. What is considered as the important places of street, are some other spots, such as office buildings and law court. They are only popular during the certain times, especially in the mornings and early evenings. Bus numbers determine the routes too. In Gainesville, Florida, shorter the number indicated shorter, local route. 1, 12, and 34 went around the campus and popular grocery stores for students. Shorter numbered buses were more frequent, and came in 5 to 10 minute interval, dividing and picking up about 300 different students from 80 different classes that end their classes at the same time. Sometimes same numbered buses came three in a row and they would carry the crowd to same designations, aligned like a train. On the other hand, 125 and 240 went all the way to downtown and hospitals.
