CTR Performance 2013/2014 Cycle Paul Mason Lynn Peterson Performance Analyst Lynn Peterson Secretary of Transportation CTR Performance WSDOT Nisqually Board Room October 23, 2015

Foreword – The Latest Aggregate Report Outdated Aggregate Report (9/18) Certain sites were initially excluded in the 2013/2014 aggregate report due to response rates. 948 Sites DAR decreased 2.2% VMT/Employee decreased 1.4% 18 million more miles annually Latest Aggregate Report (10/18) Consistent with previous cycles, some sites were added in, since their somewhat lower response rates are statistically valid 966 Sites DAR decreased 2.6% VMT/Employee decreased 3.1% 33 million fewer miles annually

The Calculations 2007/2008 2013/2014 Approach: Replicate the approved methodology used for previous cycles

The Calculations - Continued A Brief Overview: Compare baseline (2007/2008) results to current 2013/2014 results (at the jurisdiction level) Drive Alone Rate Total Weekly Trips Total Vehicle Miles Traveled (VMT) per Employee per Trip Convert the weekly survey results into annual numbers Add up and report the reductions in: Trips VMT Use a conversion factor to convert VMT into a Greenhouse Gas (GHG) reduction

Participation Between 2012 and 2014, the Board requested pilot projects, to test techniques outside of the survey. As a result, the number of surveys distributed decreased from ‘12 to ’14.

Participation Note in the baseline ‘07/’08 the return rate was 70.6% There was a drop in response rate in ‘09/’10, and ‘11/’12, with the ‘12 rate being 58.0%. However, in ‘13/’14, the response rate increased to 66.1%

Participation Between 2012 and 2014, the Board requested pilot projects, to test techniques outside of the survey. As a result, the number of worksites distributed decreased from ‘12 to ’14.

Non-Drive Alone Rate In the baseline year, the non-drive alone rate was 34.3% In subsequent years, the rate has been roughly 37% So, despite an increase in the number of employees affected by the program, the mode split for CTR sites has been able to maintain itself around 37%

Vehicle Miles Traveled and Greenhouse Gases While the above numbers may not look impressive on the surface, the bigger story is that even with a growing economy and adding more and more employees, the vehicle miles traveled per person has improved, decreasing by about 3% from the baseline.
