Overview:

Summary: High levels of traffic contribute to heat and exhaust, adding to the urban heat island effect. Increasing bikability and walkability can suport efforts to reduce traffic and change mobility patterns.

Implementation: Restrict vehicles in certain areas or at certain times of day to reduce congestion and encourage walking and cycling.

Considerations for Use: Policies restricting vehicle access can be piloted on specific days (e.g. weekends) or during particular seasons (e.g. summer) to ease adoptance and generate community support.

• Policy Levers:
  
  
  MandateMandates are government regulations that require stakeholders to meet standards through building codes, ordinances, zoning policies, or other regulatory tools.
• Trigger Points:
  
  
  City planning processesIncludes city initiatives such as the development of climate action plan, pathway to zero-energy, master plan, transit plan, energy mapping etc.
  No-regrets actions (low cost/low effort but substantial benefit)Interventions that are relatively low-cost and low effort (in terms of requisite dependencies) but have substantial environmental and/or social benefits.
