| Figure 1 shows commute trips from downtown Seattle, color-coded by destination neighborhood. |
I got curious about
commuting speeds because my average speed biking to and from work regularly
exceeds my average driving speed. I live
in West Seattle and work in Fremont and I wondered what the trend might be for
the rest of the city.
Using the
PlaceProps Analytics database of more than one million trips, made by a curated
panel of 2,500 Seattleites dating back more than a year, I looked into the statistics
for afternoon commutes for 12 neighborhoods around Seattle (see Figure 1). Our data show that the average speed of rush hour trips, originating in downtown Seattle between 4:00 and 6:00 PM and
longer than two and a half miles, is 14 miles per hour regardless of
destination.
The
map below shows the average speed of trips that originate in downtown Seattle
and end in one of the twelve neighborhoods.
The bigger the blue bubble is, the faster the average speed of trips
that end in that neighborhood.
The yellow circle
is 2.5 miles in radius and it sorts the neighborhoods into three groups: Outside
the Circle, Edge Cases, and Inside the Circle.
Outside the Circle: For
neighborhoods outside the circle, drivers are using primary roadways like SR99
and I5. The average speed is about the
same no matter where you are headed.
That is the surprising bit: north, south, or west just doesn’t matter.
Edge Cases: Speed decreases as
folks travel to Beacon Hill and Queen Anne.
Trips shift from primary to secondary streets and the number of cyclists
and pedestrians rises.
Inside the Circle: If
you live in a neighborhood within 2.5 miles of downtown, your average speed on
the way home from work is pretty slow, about 5 to 6 mph. Folks from Capitol Hill and Central District
are using congested city streets or are walking home from work – which brings
the average speed down and the heart rate up.
Those hills are steep.
So, short commutes
are the slowest commutes, and once you get on to a high speed road at rush hour
you can expect to move at the blazing speed of about 14 mph no matter which way
you are heading: it is slow no matter where you go.
Have you found any
tricks to speed up your commute home?
