Objective
Use GIS data to form a bikability rating system for
Bellevue’s roadway network.
Bellevue, WA

Data Collection• King County GIS Center– King County Bike Facilities– Metro Transit Bus Stops– Metro Transit Bus Routes– Transportation Network
• City of Bellevue Standard Data– 2 Foot Topography– Street Network
• Google– City of Bellevue aerial photograph

Analysis - Criteria
• Rated bike network based on:– Type of facility– Slope– Speed Limit– Along bus route– Proximity to bus stops– Along truck routes

Model Equation
Rating = 1.00 * [Bike Facility Type] + (0.85 * 40) * [Slope]+ (0.75 / 10) * [Speed Limit] + 0.25 * [Overlaps Bus Route] + 0.25 * [Overlaps Truck Route] - 0.3 * [Within Bus Stop Buffer]
• The smaller the rating the more bikeable the roadway.

Results• Found best routes• Examined streets to
verify index• All interstates & state
routes - dangerous
