Near-wake dispersion of light-duty truck emissions: impact of fuel type and vehicle speed

Puntos clave

• Emissions dispersion varies significantly with changes in vehicle speed and fuel type, impacting local air quality.
• Key evidence includes changes in emissions noted between different fuels at varying speeds, highlighting differences in pollutant release.
• Observational analysis assesses how fuel type and vehicle speed influence emissions dispersion around light-duty trucks on urban roads.
• Findings may enable better regulatory policies targeting fuel choices and vehicle speed limits to reduce air pollution.
