This page contains the summaries and graphs of the travel times of the
highways I monitor for each weekday. Occasionally, there are
"glitches" in the graphs. This is because sometimes a valid travel
time is not reported at that 10 minute interval on that day of the
week; in such cases, I insert the minimum possible travel time. Note
that the y-axis for I-90 is larger than the other axes. The time period is
from July 12, 2002, through 5pm on June 4, 2004.
