Why do some bus shelters face the road and some don't?

Bus shelters face the road to provide passengers with a clear view of oncoming buses, making it easier for them to identify when their bus is approaching. In contrast, some shelters may be oriented differently due to space constraints, local urban design, or to reduce noise and wind exposure for waiting passengers. Additionally, orientation can be influenced by safety considerations, such as minimizing conflicts with traffic or providing better visibility for drivers. Ultimately, the design of shelters is often a balance of functionality, safety, and aesthetics.
