Supporting Mode Shift
We must fundamentally change the way people, goods, and services move throughout the city to meet our climate goals. The National Household Travel Survey (2017) found that nearly half of all personal vehicle trips are within three miles. Many of these shorter vehicle trips could shift to walking or biking modes, and many longer vehicle trips could shift to transit service. Policies and investments that support the change in transportation methods, referred to as mode shift, also safety priorities like Vision Zero - Seattle's plan to end traffic deaths and serious injuries on city streets by 2030 - also help reduce barriers to economic success and the inequitable health impacts of transportation emissions on environmental justice communities in Seattle.
Recent analyses estimate that 30% of trips are currently zero- or low-emission trips. To achieve the additional 60% reduction in zero emissions trips needed by 2030, approximately 30% more vehicle trips need to be zero emissions (e.g., electric vehicles) and 30% more trips need to shift from vehicles to other zero-emissions modes (e.g., walking, biking, transit).
