1. The bus system is one of the main public transportation networks across the city of Los Angeles. For people without cars, being familiar with the regular routes and schedules of bus lines like the Big Blue Bus, Metro, and Bruin Bus can be vital in navigating the city.
2. Exit signs by doors generally follow a set style for their physical design in order to make them easily recognizable and consistent throughout the buildings in the city. They are permanently illuminated with special chemicals or rechargable electric systems in order to maintain readability when there is smoke or failure in general electricity. Color scheme also is always set to red or green so people know what color to look for when seeking an exit.
3. Address numbers on buildings create a physical network system allowing for greater organization in identifying where certain buildings are. Numbers present a more concrete way of finding houses relative to one another in comparison to just names, which often do not have a clear correlation to each other.
