The calendar quarter line depicted in Figure 11a and 11c shows the longest travel time in the 3rd quarter represented by July. In contrast, the longest travel time for the seasonal quarters occurs in the spring quarter (May) and the shortest bus travel time occurs in the summer (August) quarter. The different quarter aggregations for bus transit seem to give us conflicting results for quarterly travel time differences. This is likely further indication of the volatility of the bus transit monthly values.
