Environmental and Wellbeing data collection

Equitable Mobility’s overarching research focus is on how vulnerable people (young, old, disabled, poor) face challenges on their daily journeys – commuting, school, access services.

It seeks to understand what is their exposure to different environmental stressors (air pollution, temperature, noise) and how this varies by: urban form (including locations identified as having problematic infrastructure during the P-GIS phase of the project); mode of transport; by type of vulnerability. Also, what are their levels of stress during their daily commutes? Are they affected in the same way by these factors.

Locations and participants

Data collection will take place in Nairobi and Mombasa between July and October 2021.

Stage 1: Usual daily commutes

People will be asked to go on their daily commutes carrying sensors to collect the following information:

Sensors that will be used for the transect surveys.
  • Particulate Matter (PM)
  • Carbon monoxide (CO)
  • Temperature
  • Noise
  • Heart rate variability

Stage 2: Fixed transect routes

We will select locations from Stage 1 to explore in more detail. For example, if a particular street or interchange appears to be associated with high stress levels we will design fixed transect routes and ask people to carry the same sensors as above but follow a fixed transect route that will allow us to gather more information.
