Mobility problems in the city using the example of Radom

For centuries, humans have been involved in the construction and expansion of cities. A variety of social and economic activities are conducted in these cities. This article presents selected problems related to human functioning in urban areas. They are documented with numerous photographs from Radom.1. INTRODUCTION
At the beginning of the 19th century, no more than 30 million people lived in cities around the world. This accounted for 2.5% of the world’s population. Over the next 100 years, this number grew to 2 billion. In 1960, according to a World Bank report (Cities in Transition, 2000), the urban population already accounted for nearly 25% of the Earth’s inhabitants. Currently, more than half of the Earth’s population lives in cities. Forecasts suggest that by 2030, more than 60% of people will live in cities [10,16].
In the twenty-seven countries of the European Union, on average, about 74% of the population lives in cities, and in countries like the Netherlands or Great Britain, it is as much as 90%.
As can be seen, the number of city dwellers is increasing rapidly [22]. This applies primarily to cities in developing countries. In 1950, there were only 8 urban agglomerations in the world with a population exceeding 5 million, and only two of them were located in developing countries. According to the forecast for 2015, there will be 37 such urban centers, of which only 9 will be located in developed countries. Cities today occupy 2% of the Earth’s surface but consume 75% of its resources.
In cities, numerous problems related to the fulfillment of various transport needs are concentrated in a limited area. Statistical city residents travel 500-600 times a year. The number of trips is almost independent of the size (…)
