Streetsmart is a comprehensive clearinghouse of information concerning why and how to create healthy, inclusive and sustainable transportation systems. It aims to change the factors considered in the decision-making process so that climate change, public health, and equity are fully considered. It draws from research in political science, knowledge utilization, and evidence-based policy to inform our approach:
  • The aim of evidence-based policy is to inform democratic decision-making.
  • Evidence must be embedded in compelling narratives to be influential.
  • Evidence is necessary but not sufficient. Professional judgment and the voices of residents are equally important for decision-making.
  • The type of evidence matters: systematic reviews offer strong internal validity but lack generalizability to different contexts. Context-based evidence is important to understand what truly works for different places and populations.
  • Community engagement is therefore essential to successfully planning, designing, and implementing plans and projects. 
For each goal it provides a variety of implementation resources produced by leading professional organizations and research institutes.

The Research

The current beta version of Streetsmart builds on four sets of research reviews. Research related to physical activity, walking, and bicycling draws from the Built Environment Approaches Combining Transportation System Interventions with Land Use and Environmental Design and County Health Rankings & Roadmaps. These research syntheses involve an extensive review process. For example, this American Journal of Preventive Medicine article written by the Community Preventive Services Task Force explains the Community Guide systematic review methodology. ​​

Research related to vehicle miles traveled and greenhouse gas emissions draws from Research on the Impacts of Transportation and Land Use Related Policies, commissioned by the California Air Resources Board in response to California Senate Bill 375. Streetsmart also draws from Mark Stevens' meta-regression analysis as described in the journal article, Does Compact Development Make People Drive Less? and interpretations of the study expressed in reaction articles in the same issue. 

Streetsmart will increasingly draw from context-based research approaches to offer better contextual guidance. Examples include realist evaluation--which asks "What works, for whom, in what respects, to what extent, and in what contexts?"--case study research, and Community Based Participatory Research projects. ​​​​​
