Which bus option experiences higher variability in arrival times based on the weekly data?

The selection of the local bus as having higher variability in arrival times can be understood by considering the nature of local bus services. Typically, local buses make more stops than express buses, which can lead to delays due to passenger boarding times, traffic at various stops, and other urban factors. This increased number of stops and interactions with passenger flow often results in a greater inconsistency in arrival times compared to express buses that follow a more direct route with fewer stops.

Research or observational studies on bus schedules frequently show that express buses tend to maintain a more consistent schedule due to their limited stopping pattern and priority lanes, whereas local buses are more susceptible to fluctuations caused by external factors such as street congestion, community events, or variability in passenger volume. Thus, when analyzing weekly data, it is reasonable to determine that the local bus exhibits greater variability in its arrival times.
