An efficient and fair transportation system must serve diverse users. The "Transportation for Everyone" rating system evaluates transport system diversity and, therefore, its ability to serve all community members.
An important current policy debate concerns whether the next U.S. federal surface transportation reauthorization should require spending on “enhancements,” which finance projects such as walkways, bike paths, highway landscaping and historic preservation.

In other words, should non-motorized modes be considered real transportation.
