The study analyzed aspects of reducing the environmental impact of transport based on reducing the time to find parking for a car. The time spent by drivers searching for parking in the central part of the metropolis was analyzed. Data on the amount of time spent was obtained by interviewing drivers. The survey was conducted after completing a task to find parking in the central part of the metropolis at a certain time of the day (morning rush hour, daytime, evening rush hour). The data obtained reflect the time spent by drivers searching for parking in the central part of megacities; the data allows us to estimate the amount of environmental load arising from the “useless” movement of vehicles in the center of the metropolis, arising from the lack of free parking spaces. These studies can be used in the development of parking space planning programs and environmental programs aimed at improving the environmental situation in cities.
