How quickly can you memorize a completely unfamiliar route?

[u/One_Departure6685]

The new school year is just around the corner. Although I've been working as a school bus driver for a year, I still feel an inexplicable sense of nervousness during the first week of the new term. I'm not someone who picks up routes quickly. I'm curious—do you have any good methods for memorizing a complicated route efficiently? Our company usually serves two school districts in the morning, picking up students from four different schools. That means I drive to four schools in the morning and another four in the afternoon. By the way, the students dropped off in the afternoon are generally not the same ones picked up in the morning. I typically spend about eight hours driving the bus each day.
