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
