WalkSanDiego made recommendations for Complete Streets supportive policies through the release of its Safe for All report:

• Plan streets to be safe for everyone. For years, traffic engineers have planned roadway design around Level of Service of the automobile - how efficiently cars will move through intersections and road segments at various times during the day. However, this doesn't really address other roadway users, like pedestrians and bicyclists. With a newly approved California manual, traffic engineers now have access to a methodology that considers all roadway users in estimating how a new design will function -- multi-modal LOS. The jury is still out as to how well this methodology performs, but the good news is that we are on the road to better balancing all of our needs.
• Adopt Policies Supportive of Multi-Modal Streets. Currently, cities have policies that require them to provide roadway improvements should the Level of Service fall below certain conditions. However, cities have it within their power to change this, especially on downtown kind of streets where there is more pedestrian and bike traffic. Some cities within the region have already adopted similar policies.
• Slow cars down. Studies have shown that high speeds are a major deterrent to having more people get out of their cars to travel. WalkSanDiego recommends cities to be strategic and identify streets with speeds upwards of 35 mph. Once the streets are identified, look at tools to calm traffic, especially in areas near schools, downtown areas, and transit routes.
• Put roads on a diet. Did you know that roads can 'lose weight' similar to humans? It simply means that they lose a lane or two. In fact, cities across the country are learning the tremendous value of road diets. Imagine a standard road with 4 lanes of traffic - 2 lanes in each direction with a painted yellow lane in the middle and no bike lanes or sidewalks on the side. By eliminating a travel lane in each direction (by repainting the stripes), suddenly, there is room to have a bike lane and/or a sidewalk making the street safer for all users. Road diets have in fact been proven to reduce pedestrian crashes 29%. WalkSanDiego recommends that cities conduct a comprehensive assessment of roads that can be placed on a road diet and take action.
• Adopt a strategic plan. Cities around the U.S. who are successfully making valuable, lasting change to their roads are developing a strategic plan that prioritizes goals and specific actions. Charlotte, NC and Seattle, WA are two such examples with 5-year Transportation Improvement Plans. This allows staff and decision makers to create a specific, longer-term vision on outcomes they want for their streets and to plan accordingly.
• Ensure new development projects complete the street.
• Adopt a Complete Streets policy.
