Title: CTR Tracts
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
This dataset contains commute trip data from the 2015/2016 biennial CTR survey of employees working in the state of Washington. Survey participants record one week of AM commute trip data. The data was aggregated by worksite, weighted by response rate, extrapolated to all employees at worksites, aggregated to Census Tracts, and joined to 2016 Census Tract geographic data, as delineated by the U.S. Census Bureau.Worksites participating in the CTR program have at least 100 full-time employees that report to work between 6-9 am. CTR worksites are located in the following counties: Clark, King, Kitsap, Pierce, Snohomish, Spokane, Thurston, or Yakima. For more information on the CTR program, visit: <http://www.wsdot.wa.gov/transit/ctr>.
Purpose:
2015/2016 Commute Trip Reduction (CTR) survey data for the State of Washington aggregated at the Census Tract level.

Attribute:
Attribute_Label: VMTperEmployee
Attribute_Definition:
Vehicle miles traveled (VMT) per employee is the average number of equivalent one-way single occupancy vehicle (SOV) miles traveled by employees, weighted by worksite response rate. For further details on how VMT is calculated, please contact Michael Wandler (wandlem@wsdot.wa.gov) or Rich Lee (leerich@wsdot.wa.gov).
Attribute:
Attribute_Label: NDATRate
Attribute_Definition:
Non-drive-alone trip (NDAT) rate is the percentage of trips made by non-SOV modes (e.g. transit, carpool, vanpool, bike, walk, telework), weighted by survey response rate.
Attribute:
Attribute_Label: TotalAnnualGHG
Attribute_Definition:
Total annual greehnhouse gas (GHG) emissions is the estimated annual commute-related CO2 for all CTR worksites within the Tract, extrapolated to all employees at the worksites. The results are based on EPA estimates and shown as equivalent metric tons of CO2. For further information on how this is calculated, contact Michael Wandler (wandlem@wsdot.wa.gov) or Rich Lee (leerich@wsdot.wa.gov).
Attribute:
Attribute_Label: DailyGHGperEmployee
Attribute_Definition:
Daily greenhouse gas (GHG) emissions per employee is the estimated daily roundtrip commute GHG (in equivalent pounds of CO2) per employee, weighted by survey response rate. For further information on how this is calculated, contact Michael Wandler (wandlem@wsdot.wa.gov) or Rich Lee (leerich@wsdot.wa.gov).
