Which statement best describes the visibility of bus schedules on CTA buses?

The statement that schedules are posted at most stops accurately reflects the efforts made by the Chicago Transit Authority to ensure that passengers have access to important route information. By placing bus schedules at most stops, the CTA enhances visibility, making it easier for riders to plan their journeys and wait for buses without uncertainty. This practice allows passengers to see arrival and departure times as well as route details, contributing to a more efficient and user-friendly transit experience.

In contrast, the other options neglect the widespread availability of bus schedule information. For example, the notion that schedules are available only inside the bus limits access to passengers who may not board the bus to verify times beforehand. Similarly, stating that schedules are not provided to passengers entirely undermines the CTA's commitment to transparency and rider assistance. Lastly, the idea that schedules are emailed to customers suggests a reliance on technology that may not reach everyone, especially those who may not have reliable internet access. Thus, the presence of posted schedules at bus stops represents an accessible and practical solution for enhancing public transportation information.
