The Transportation Map Series explores the region’s transportation system with a focus on active transportation options:  transit, walking, and biking. The maps document the distribution of walkable neighborhoods, bikable streets, and public transit options, and show how these resources compare with demographic patterns, highlighting the areas where inequities in access to transportation impact the mobility and opportunity of low-income populations, populations of color, youth, and seniors.
