Public parking is an inseparable element of the cities. Parking shortage brings
many direct and indirect negative impacts on the citizens' life, including
wasting citizen's time while seeking barely found parking spots, and increasing
vehicle traffic and air pollution. Our analysis of the supply and demand of
parking spaces in Tehran, Iran shows Tehran lacks about 40\% of its parking
spaces causing the citizens to suffer daily. Assessment of unfavorable impacts of the parking shortage and the way citizens deal with it can be used for better parking management by the city managers and policymakers. To this end, in this research, we conduct a questionnaire survey to extract and assess Tehran citizens' opinions on different aspects of the issue. A 19-question survey with five main categories was designed. These categories include,1)the extent of the wasted time for finding free parking spaces, 2) citizens' priorities for the type of the parking spaces, 3) price of the parking spaces, 4) type of complementary facilities, and 5) the main sources of the public parking issues. The results achieved in the survey indicate severe impacts of the parking issue on the citizens' life. For example, 74\% of the respondents indicated that on average they spend more than 10 minutes for finding free parking spots in the city while 65\% of them suffer from high tension and stress during this time. About 66\% of people expressed they have witnessed or even have been involved in the street fights and quarrels on free parking spaces. The lack of free parking space, with the frequency of 78\%, and the poor public transportation, with the frequency of 42\%, were found in the survey as the main sources of the parking issue on the citizens' point of view. In the current situation, parking price, type of parking space and complementary facilities in the parking buildings are not the citizens' main concerns. Though, being able to find a parking space, not so far from their destination, is the main preference.
