Increased Social Interactions

Transportation access can play a key role in addressing social isolation and loneliness. Social interactions and connectedness are a key determinant of health, and, unfortunately, fewer social interactions and increased loneliness can lead to poorer health outcomes and increased risk of mortality. This is particularly true for certain populations, such as older adults or adults with disabilities, who often travel less than other people due to their physical and/or mental restraints. These individuals also often have unique mobility needs that deserve attention, such as requiring more frequent medical care. Additionally, lower-income individuals who cannot afford a car or live in more rural areas can feel more socially isolated due to a lack of transportation options. However, public transit facilities can provide opportunities for transportation-related social interactions. As the proportion of older adults in the United States increases, it is imperative that the transportation infrastructure is designed to foster community interactions.

This indicator helps determine the effectiveness of the following objectives

  • Less Contamination
  • Less Emissions
  • Less Traffic Noise
  • Connectivity and Inclusion
  • Healthy Destinations
  • Less Traffic Violence
  • Active Transportation
  • Green Space

Data Collection

Although it is difficult to measure the number and quality of social interactions, this can be done by using surveys that ask participants about self-reported loneliness and other risk factors. For example, various surveys estimate that approximately 30% of U.S. adults ages 72 and older report feeling lonely at least some of the time. This can be due to physical and mental declines that prevent this population from accessing transportation. Local-level community health assessments (CHAs) can also offer insight into specific population’s needs, such as a lack of a stable social network due to transportation issues.

Examples

Healthy Places by Design

Healthy Places by Design is a group of strategic partners that aim to advance community-led action to ensure health and well-being. They recommend that the transportation begin prioritizing social connections to improve overall community health. This can be done by policies that invest in public transportation and walking and bicycling networks.
