Trends in passenger travel no longer seem to closely track trends in economic activity. Changes in gas prices have had a role in affecting travel behavior, but their impact on VMT is rather weak. The urban form of American cities is changing. Current sociodemographic trends of U.S. households (including lifecycle effects, period effects, and generational effects) unveil potentially lasting effects on travel demand. Individuals belonging to all generations have become frequent users of modern technologies. A new generation of technology-enabled shared mobility services is quickly reshaping transportation by offering users new ways to get to their destination, a wider set of travel options and increased flexibility (on where and when to travel) without the fixed costs of owning a private vehicle.
It’s not theoretical, it’s political.
Engineers and planners are smart people, they can find solutions, they need direction

DESIGN FLAWLimited Access vs Fine-grained Network
“...frequent streets and short blocks
are valuable because of the fabric
of intricate cross-use that they
permit among the users of a city
Building of a highway “has about
the same result upon vegetation
and human structures as the
passage of a tornado or the blast of
an atom bomb.”
1. Strong community support with extraordinary leadership
and political will
2. An urban vision for the city that is not dominated by the
automobile; prioritize the short trip vs the long trip
3. Decision processes driven by long-term community
investment versus spending federal allocations on projects
within given timeframes.
4. Regulatory (FBC) and Land Disposition Control
