Executive Summary
The 2003 Campus Master Plan specifies a set of monitoring and reporting activities that should be
undertaken to measure performance of the University’s Transportation Management Program
(TMP). This includes the Annual Campus Traffic Count as reported here. This report retains
continuity with past reports. However, in 2003, the number of locations in East Campus included in
the count was increased. The extent to which apparent trip growth is attributable to this change in
methodology is described in the report.
In 2008, there were 5,958 morning peak period inbound vehicle trips (of these 445 were from new
locations in East Campus) and 8,832 afternoon peak period outbound trips (of these 603 were from
new locations in East Campus). The total 24-hour count was 60,107 (with 3,979 of these trips
associated with new locations in East Campus).
On the following page, figure 1 summarizes the average 24-hour traffic counts. The portion of the
total count that is from the new locations in East Campus is indicated in grey. As the figure shows,
more trips were generated in 2008 than in 2007.

Introduction
This report documents the 2008 Annual Campus Traffic Count. It includes results and analysis of
the 2008 data and a historical comparison of the results from 1983 through 2008. The University of
Washington Commuter Services conducted the 2008 count during the week of Monday, October
20th through Friday, October 24th. The temperatures were typical for this time of year, with highs
in the mid 60’s and overnight lows in the upper 30’s. The weather was cool and pleasant; however,
on Monday and Friday, the temperature dropped and it rained. Due to issues with traffic counting
equipment at Gate 5, Gate 6 Bypass, Gate 7, and Walla Walla Road, these few locations were
recounted during the week of Monday, November 3rd through Friday, November 7th, and the latter
data was used in the analysis. The weather that week was cool and rainy, with temperature highs in
the upper 50’s and overnight lows in the low 40’s.
Background
A 1983 agreement between the University of Washington and the City of Seattle established specific
traffic and transportation goals and objectives to control traffic congestion on city streets adjacent to
campus. Following the adoption of the Campus Master Plan in 2003, the limits placed on the
University were changed from limits on total vehicle trips to and from campus, to limits on faculty,
staff, and student vehicle trips to and from campus. The Annual Campus Traffic Count, which
monitors total vehicle trips without differentiating by trip purpose, will continue to be conducted for
the sake of historical comparison.
Study Methodology
The Annual Campus Traffic Count has two phases: data collection and data analysis.
Data Collection
The Seattle campus was divided into four sectors, illustrated in Figure 2. Each sector has specific
entry/exit locations, listed in Table 1. Traffic Data Gathering, a private consultant, equipped each
location with portable traffic counting equipment. The equipment counted all vehicles entering and
exiting each location during the study period. West Campus is bisected by city streets and has no
central counting location. As a result, traffic in West Campus is partially estimated. Traffic Data
Gathering provided the raw data to the University of Washington Commuter Services at the
conclusion of the collection period.

The definition of a vehicle trip is a single directional trip that has one origin and one destination. A
typical vehicle trip to campus originates off campus, enters campus, and then terminates in a campus
parking lot. The vehicle makes a second trip when it leaves the parking lot for an off-campus
destination.
However, it is important to note that all vehicles entering and leaving the survey locations were
counted, regardless of the purpose of the trip or the type of vehicle. University-owned vehicles,
contractors’ vehicles, transit vehicles, and private vehicles were all counted, as were vehicles driving
through without stopping on campus. This methodology does not allow one to distinguish trips
made by faculty, staff, and students, from trips made by visitors to the University and patients to the
University of Washington Medical Center.

Data Analysis
For each location, trips were counted by direction (inbound/outbound), day of the week and hour
of the day (see Appendix A).
In this report an inbound trip refers to a vehicle entering a campus area from a non-campus area.
Likewise, an outbound trip refers to a vehicle leaving a campus area for a non-campus area. The
outbound trips are adjusted in this report in order to match daily inbound trips (see Appendix B).
The number of total vehicle trips is the sum of the inbound and outbound trips.
The traffic volumes in the peak traffic periods are highlighted in the report. The morning peak
period begins at 7:00AM and ends at 9:00AM. The afternoon peak period begins at 3:00PM and
ends at 6:00PM. These periods were specified by the City of Seattle when the traffic caps were
established in 1983. The actual AM peak in vehicle trips now appears to be between 7:00AM to
10:00AM. For the purposes of report consistency, the AM peak is still reported as 7:00AM to
9:00AM.
This analysis did not attempt to determine which trips were intra-campus trips (for example, those
by University vehicles), nor did it identify bus trips or service vehicle trips. Furthermore, this
analysis did not include a method to estimate how many of the total trips pass through campus
without stopping. Additionally, vehicles may have been counted multiple times by driving through
one campus area to another.
The hourly directional counts for each campus sector were added together for the five-day period.
This sum was divided by five to obtain the average hourly directional volumes. The sectors were
then added together to obtain the total campus average hourly directional volumes. Finally, the total
campus hourly volumes were added to obtain the 24-hour volumes.

Traffic Count Results
Total Campus
The average number of daily inbound and outbound vehicle trips was 60,107 in 2008. Compared
with 53,568 daily trips in 2007, the number of trips was about 12.2% higher in 2008. Of the 60,107
daily trips in 2008, approximately 4,000 of those trips can be attributed to areas in East Campus that
were not counted in years prior to 2003. Not including these new areas, there were only 56,128 daily
trips, a seven-percent decrease in average daily trips for campus as a whole compared to the 2002
count of 60,010 for the equivalent area.
Figure 3 illustrates inbound and outbound average daily trip distribution.

Main Campus
Main Campus vehicle trips were counted near Gates 1, 2, 3 and 5, and at the south entrances/exits
to the Central Plaza Garage. The average number of daily trips at Main Campus was 27,264 (13,632
inbound and outbound). Main Campus trips constitute approximately half of all Campus trips.
Compared to 2007, there were 754 more daily vehicle trips at Main Campus in 2008, a 2.8%
increase.
Figure 4 illustrates inbound and outbound average daily trip distribution. The distribution of trips at
Main Campus is more widely spread than some areas of Campus due to a larger proportion of
visitors.

East Campus
Beginning in 2003, the whole of East Campus was considered a single area—instead of only
counting the Stadium Lots and the Montlake Lots separately. Trips were previously counted at
Montlake Boulevard at Pacific Place, at the Montlake Boulevard entrance to lots E-11 / E-12, at the
three southern entrances/exits to E-1, at E-1 Walla Walla Road entrance, at E-1 Clark Road, and at
E-5 Douglas Road.
The new methodology in East Campus added the following sites to the locations previously
counted: E-16, Clark Road at Mary Gates Drive, Walla Walla Road (south of Wahkiakum), and
Canal Road. The decision to expand the areas covered by the count in East Campus was made in
recognition of the fact that a more complete picture of trips to and from East Campus was possible
with the addition of very few additional count locations.
Subsequent changes were made in 2005 with respect to data collection and analysis in East Campus.
With regard to data collection, Canal Road was not included in the 2005 count due to low vehicle
counts in 2003 and 2004 (6 and 24 trips, respectively).
With respect to data analysis, changes were made to the methodology used for calculating the sector
total. Due to the arrangement of counting locations, vehicles entering/exiting two locations – the
Clark Road entrance/exit to E-1, and the E-5 entrance/exit - cross two counters: one on Clark
Road, and another at each respective lot entrance/exit. In 2003 and 2004, totals from all of these
locations were included in the total for East Campus, resulting in double-counting trips
originating/ending at these lot entrances/exits. To correct for this error, these two locations were
not included in the totals for East Campus as of 2006. Without this change in methodology, more
than 1,060 trips would have been double-counted in 2008.
The average number of daily trips in East Campus was 13,293 (6,646 inbound and outbound). Of
these daily trips, 3,979 are from parts of East Campus not counted in the years before 2003.
Compared to 2007, there were 1,093 more daily vehicle trips in 2008, an increase of nine percent.
On the following page, figure 6 illustrates inbound and outbound average daily trip distribution for
2008.

West Campus
A complete traffic count was conducted at West Campus Garage. These trips were added to the
trips from West Campus surface lots, which were estimated using the following method (see
Appendix D for more details):
1) Estimate the number of parked vehicles by subtracting empty spaces from lot capacity.
2) Estimate one-way trips by multiplying the turnover factor (1.2 1 ) by the number of parked
vehicles (a vehicle makes trips to a parking lot 1.2 times a day – the factor is consistent from
year to year).
3) Redistribute one-way trips to match the hourly trip distribution measured at the West
Campus Garage.
The average number of daily trips at West Campus was 3,370 (1,685 inbound and outbound).
Compared to 2007, there were 935 more trips in 2008, a 38.4% increase. West Campus was the
sector to experience the most significant increase in vehicle trips compared to 2007.

Following the 2002 Annual Traffic Count the accuracy of the turnover factor of 1.2 was questioned. Commuter
Services staff and City of Seattle staff discussed several methodologies for estimating a new turnover factor. However,
West Campus lot-geometry poses serious challenges to traffic counting. It was determined that there was no reliable
way of knowing if a new estimate was more accurate than the historic turnover factor. Therefore, for the sake of
maintaining historic consistency, it was decided that the turnover factor of 1.2 would continue to be used.

2008 Annual Campus Traffic Count
Table 6 summarizes 2008 daily peak period trips in the West Campus sector, and compares them to
2007. As in previous years, trips in West Campus were much more concentrated in the peak periods
compared to other sectors of campus, likely due to the predominance of commuters who park in
this area. In 2008, the concentration of both inbound and outbound trips increased, however the
concentration of outbound trips increased significantly compared to 2007.

Historical Data
Figures 8, 9, and 10, show campus traffic count data from 1983 through 2008. The Annual Campus
Traffic Count allows trends over an extended time period to be observed and provides information
regarding vehicle trip behavior on campus.
Morning Peak Trips
Figure 8 shows how the U-PASS Program has reduced morning trips. Average morning peak
inbound trips dropped dramatically when the U-PASS was introduced between 1990 and 1991, and
they have remained well below pre-U-PASS levels. The peak periods were specified by the City of
Seattle when the traffic caps were established in 1983. The actual AM peak in vehicle trips now
appears to be between 7:00AM to 10:00AM. For the purposes of consistency, the AM peak is still
reported as 7:00AM to 9:00AM.
In 2008, there were 5,958 morning peak inbound trips. Of these, 445 were from areas in East
Campus that were included in the traffic count for the first time in 2003. The trips from the new
count locations are indicated by the grey portion of the bar for 2003 through 2008. The 2008
morning peak trips for the whole campus and the East campus’ added sites increased since 2007 by
6% and 9%, respectively. However, the total morning peak trips for the whole campus are still well
below the 1983 morning peak trips according to both pre and post-2003 methodologies.

Figure 9 illustrates how the U-PASS Program reduced afternoon peak period outbound trips. In
2008, there were 8,832 afternoon peak outbound trips. Of these, 603 were from areas in East
Campus that were included in the traffic count for the first time in 2003. The trips from the new
count locations are indicated by the grey portion of the bar for 2003 through 2008. The 2008
afternoon peak trips for the whole campus and the East campus’ added sites increased since 2007 by

Figure 10 shows the number of average 24-hour vehicle trips each year since 1983. In 2008, there
were 60,107 total daily trips. Of these, 3,979 were from areas in East Campus that were included in
the traffic count for the first time in 2003. The trips from the new count locations are indicated by
the grey portion of the bar for 2003 through 2008. The 2008 24-hour trips for the whole campus
and the East campus’ added sites increased since 2007 by 12% and 7%, respectively.

2008 Annual Campus Traffic Count
Conclusions
Using the pre-2003 set of counting locations, the 24-hour vehicle trips, morning and afternoon
peak vehicle trips for the whole campus increased by 6%, 11%, and 12%, respectively, since
2007. Peak trips to and from the post-2003 locations on East Campus (E-12, Clark Road at
Mary Gates and Walla Walla Road), however, increased by 9 percent in the morning and 12
percent in the afternoon since 2007. The average number of daily trips increased in every sector
of the campus. Even though there was an increase in traffic volume from 2007 to 2008, traffic
volumes are still low relative to the campus population. Looking historically at comparible
traffic counts, the 2008 traffic volume is the same as the 1998 traffic volume; however the
population at the University of Washington has increased by 26.8% since 1998.
