Transportation Programming Tool (TPT)
This tool will allow planners to predict the likely benefits of proposed non-motorized transportation projects such as bike lanes and walking trails. A benefits calculator created from the LUTAQH research results will allow them to weigh the likely increases in route connectivity and transit access, as well as the decreases in conflicts with vehicles, associated with each proposal. It will also take into account factors such as population density in the surrounding community. The result will be a score for each project’s predicted transportation, safety, economic, air quality, and health benefits.

Development Impact Assessment Tool
This tool will focus on proposed land-use changes, using the study results to modify a standard modeling tool (the PLACES model) to assess the likely impacts and benefits of development plans. It will allow planners to compare baseline scenarios against various alternatives to determine the alternatives’ relative effects on transportation (i.e., transit use and walking), public health (i.e., obesity levels), and air quality (including greenhouse gas emissions).

King County Walkability Map
This map is derived from the Phase I findings and determines “walkability” based on the mix of uses, density, street connectivity, and amount of retail in the area. Residents of the most walkable areas of King County are less likely to be overweight and more likely to report being physically active.
