Commuters in various transport modes are generally exposed to a higher level of pollution. In this study, we monitored the Particulate Matter (PM2.5 and PM10) concentration inside the cabin of four different transport modes—Car, Electric Bus, Tempo, and Bike, along a 3.5 km long stretch of road and analyzed the variation of the pollutants in the transport. The data was collected using a portable laser particle counter during the evening peak hours from the period of January to March, 2024. The highest average PM2.5 concentration was found in trips conducted by Tempo at 256.7 ± 112.7 µg/m3, while the lowest were found in trips completed by car with AC and RC on at 69.6 ± 52.5 µg/m3. On comparing the effect of ventilation settings, it was found out that the modes with open/natural ventilation had higher PM concentrations than modes with closed/mechanical ventilation. These studies help in making an informed choice by the commuters in selecting their mode of travel and by the development authorities for better city planning. Further work can be done on determining the concentration of different other pollutants in the vehicle cabins.
