Mode share is the percentage of commuters that do not drive alone to get to work. This is measured by surveying employees every two years about their modes of travel as required by the Commute Trip Reduction Act. The City's goal is to reach 45% mode share by 2030.
Transit ridership is defined as the average weekday boardings for all transit stops within City limits. This measure is provided by King County Metro. City targets for 2030 are 26,700 boardings per day based on the anticipated arrival of light rail service in 2024.
Concurrency is defined as the ratio of mobility units of supply to that of demand, and is an indicator of whether the City is delivering its Transportation Facility Projects at a pace commensurate with growth. The City's goal is to maintain concurrency at 1.05 or higher.
Air quality and water quality provide insight into whether the City's transportation system is working towards clean and green community goals. Air quality is measured by adherence to federal standards. Water quality is based on the City's goal to provide basic treatments to 100% of City right-of-way by 2112.
Maintaining our streets is critical to the proper functioning of the transportation system in terms of safety and enhanced mobility. The City has established a pavement condition index of 70 or higher on our arterial streets to ensure an adequately smooth surface at minimal costs.
