Bicycling to Change Urban Transport
Transport is quickly changing
1 2 3Bicycling’s
future is uncertain
Address ‘knowledge gaps’ while
setting policy
PREMISES
1. Transport varies by culture & context 2. Development densities will increase 3. Robots are coming 4. Humans prefer to travel (& not cloister-up at home) 5. Streets can supply a “third space”
1. Transport varies by culture & context 2. Development densities will increase 3. Robots are coming 4. Humans prefer to travel (& not cloister-up at home) 5. Streets can supply a “third space” 6. Human flows will be accurately monitored 7. Energy efficiency will help guide policies

Forms of transport have big differences in energy efficiency
Bicyclist
Traffic, Technology, & getting around
town?
Things are behaving
differently
+autonomous vehicles & new vehicle types
continued advances, information tech
shared services
big changes in how roads will be used
changing demographics/preferences

BICYCLING depends on… 1. lowering its ‘generalized’ cost (relative to other modes) 2. providing intrinsic pleasure

Bicycling positive infrastructure feedback loop
REDUCE the relative &
generalized “cost” of bicycling
IMPROVE CONDITIONS for bicycling
(reduce conflict w/ fast moving cars,, provide higher quality
infrastructure)
ENHANCE bicycling
accessibility
INCREASE demand for
bicycling
Adapted from: “Diamond of Assembly” (Chapter 12, Planning for Place and Plexus: Metropolitan Land Use and Transport) & prompted by David Levinson
ASSESS degree to which “latent demand” for
bicycling is realized on city streets
Technology does not change geometric human facts
leverage accessibility coalesce vehicle types & speeds
capitalize on intermodality drill down into ‘human’ element
