The Corridor Function Map prioritizes Seattle's streets based on their character and role in the transportation network. The City has a designated set of street types, which serve as the basis for this analysis. The City's street types reflect the character of the street and its contribution to the pedestrian system. Street types also reflect the land uses adjacent to the street, which play an important role in shaping the pedestrian environment.
All street type categories were given a point value to reflect how important it is to be able to walk along the street. The streets with a darker blue color on the map provide the most important links in the pedestrian network. These streets have the most need for pedestrian infrastructure. As a result, corridor function is an important piece of the prioritization for pedestrian projects.
