Grant Description
Grants to USA, Canada, and International research teams affiliated with research organizations for studies related to the health impacts of traffic-related pollution. Applicants must submit a pre-application prior to submitting a full grant application. Funding is intended for research that addresses the effects of the evolving nature of urban transportation.

RFA 23-1 is seeking to fund studies to assess health effects of long-term exposure to Traffic-Related Air Pollution (TRAP). Studies should propose novel or improved methods and approaches to evaluate exposure to and health effects of traffic-related air pollutants as technologies and fuels change, the fleet turns over, mobility transforms, and electrification makes greater inroads.

Specific Objectives: RFA 23-1 seeks to fund studies that can accomplish at least one of the objectives listed below. Note that in meeting the first three objectives, investigators should consider whether their work can effectively include effects in marginalized communities in high-income countries.

  • In the proposed health studies, develop, validate, and apply novel or improved exposure assessment methods suitable for estimating exposures to traffic-related air pollutants that (1) account for other air pollution sources in urban areas (such as airports, (sea)ports, industries, and other local point sources), (2) could distinguish between tailpipe and non-tailpipe traffic emissions, to the maximum extent possible, and (3) take into consideration the overall impact of (new) transportation and mobility trends on air quality and exposure.
  • Evaluate the effectiveness of key measures to reduce TRAP and improve public health, as well as to assess the health benefits of measures designed to mitigate traffic or achieve other policy objectives.
  • Estimate the impacts on urban air quality and health of various new transportation and mobility scenarios, including a baseline (status quo or "business as usual") scenario.
  • Investigate health effects of long-term exposure to TRAP in understudied low- and middle-income countries.

HEI considers the following features of the study design important to meet the overall objectives:

  • Study populations
  • Study designs
  • Geographic location
  • Exposure assessment
  • Health outcomes
  • Explore the role of other factors
  • Precision and statistical power
  • Statistical methods

For additional information regarding these objectives, see:


Additional Eligibility Criteria
Studies in all urban regions of the world would be considered responsive.

Research Team:
The research team should possess the full range of expertise to conduct the proposed research. The Principal Investigator (PI) must demonstrate a record of producing high-quality and objective research in areas relevant to the proposed work and be affiliated with an established research organization. The full team can include the PI, their immediate team (other faculty, research scientists, post docs, students, and technicians), co-investigators or collaborator(s) at the same or other institutions, and consultants. Researchers are encouraged to consult with government, policy experts, and urban planners to learn more about past, current, or future urban policy interventions to obtain a good understanding of the scope.

HEI strongly encourages applicants to diversify their research teams by including individuals from groups that are underrepresented in environmental assessment and health research and, to the extent appropriate for the study location(s), attuned to and knowledgeable about the communities in which the studies will take place. For this purpose, HEI has adopted the National Institutes of Health definition of underrepresented populations in the U.S. Biomedical, Clinical, Behavioral and Social Sciences Research Enterprise. The National Institutes of Health definition of underrepresented populations includes individuals from racial and ethnic groups underrepresented in health-related sciences on a national basis, individuals with disabilities who are defined as those with a physical or mental impairment that substantially limits one or more major life activities, and individuals from disadvantaged backgrounds, recognizing that women from these three backgrounds face particular challenges at the graduate level and beyond in scientific fields.
