Timing of Transportation Transitions / by urbanexus

There is an interesting chart that appears in a new UC Davis report on imagining the future of transportation.[1] The chart comes from a 1998 article in the European Review.[2] The chart illustrates how that prior changes in transportation technology have taken 30 to 70 years to reach peak implementation.  The chart is reproduced below.
