Abstract
Climate change can severely affect the rainfall pattern of a city and thus impact transport related activities. Travel time and mileage are an important transport parameter that may significantly be affected by rainfall. Objective of the study was to estimate the difference in travel time and fuel consumption for rainfall and non-rainfall days for Greater Mumbai. The study analyzed the impact of different intensities of rainfall on travel time and mileage for two roads of Greater Mumbai. A survey was carried out to collect data on the chosen transport parameter at different rainfall intensity. Rainfall intensity was categorized based on Indian meteorological department’s standards. The results shows that travel time and fuel consumption are influenced by intensity of rainfall. Due to rainfall, there is an increase in travel time by 8-140% for both the roads studied. Also, travel time during evening peak hours is ~10% higher than morning peak hours.
