• People commuting to UW suffer delays, congestion using both public and private transportation.

• We propose a park & ride system with express shuttle service to campus from the parking location.

• Parking location needs to be centralized, yet still provide a high-speed route to campus.

• We will use GIS to perform an analysis utilizing property values and metro/traffic data.

• Analysis will provide a parking location that:

• Minimize property purchase cost

• Minimize transit time to campus

• Maximize potential system users

• Acquired data using WAGDA, sources were King County and City of Seattle.

• City of Seattle

• City boundary shapefile

• Street centerlines shapefile

• King County

• Tax parcels polygons

• Tax account description (property values)

• Park and ride location shapefile

• Metro revenue service footprint

• Constructed model by inserting base layers.

• Narrowed scope of KC data by clipping it to City boundary.

• Applied property values to parcels.

• Had to adjust PIN join field.

• Convert fields from strings to numbers.

• Calculate value/square foot.

• Apply color gradient to property values.

• Quantified requirements:

• Within mile of I-5

• Greater than mile from existing P&R

• Within 5000 feet of high-density roads

• Within 500 feet of major bus line

• Property values less than $25/square foot

• Applied buffers and eliminated parcels that lay outside buffer region (inside buffer for P&R buffer).

• Eliminated remaining parcels that exceeded price limit.

• Resulting area was dispersed along I-5 corridor, greatest density in South Seattle area

• Selected South Seattle area because it met analysis requirements, offered greatest concentration of parcels

• Recommend to UW that it look at South Seattle area for transit expansion project (park and ride)

• Work with City of Seattle planners, community to determine which specific parcels meet demands, scope of final park and ride location
