Transport and Urban Form

• Problems driven in part by high levels of
  migration, rapid urbanization, and extent of
  informal transport methods
• Rapid move from walking city to rubber-tire
  city
• Poor road infrastructure combined with
  competition for road space with walkers, hand
  carts and animal-drawn vehicles

• Costly to build
• Restricted spatial coverage
• Difficult to compete with cheaper means of
  transport

Urban Transport Strategies

• Capital intensive strategies of limited use
• Scarcity of public resources and individual
  income limits options
• Walking, non-motorized and motorizes IPT systems
  likely to continue to be important

Take-home messages

• Traffic problems in 3rd world cities involve a
  complex mix of diverse transportation needs and
  conflicting urban form
• Transport options involve more collective, public
  systems than in developed nations
• Public transport strategies, however, are
  constrained by limited resources
