The three Indicators in the Transportation and Infrastructure Topic measure the different ways Oaklanders travel in the city. The first Indicator measures racial and ethnic disparities in car access, which is important due to the heavy reliance on cars for commuting to work, school, and other places. The second Indicator measures the frequency of buses along each segment of the network and compares majority non-White/mixed and majority African American census tracts. The third Indicator is a citywide measurement of curb ramps that are accessible to individuals with limited mobility, including seniors and those with physical disabilities.
