The Influence of Road Congestion on Urban Mobility

Urban mobility is defined by all the travel possibilities within a city and their spatial arrangement. In recent times, the world's major cities are changing their infrastructure to accommodate alternative and public transport modes and are also developing car-free policies as they increase mobility and pursue a sustainable future. Congestion in road traffic is defined as the phenomenon of the reduction of vehicle flow speed to the point of zero due to so-called sensitive areas on the road. This scientific paper has been developed by the authors in a logical and elegant manner, which deals with the influence of road vehicle traffic congestion on urban mobility in cities in the European Union. In this way, those interested can get acquainted with the main factors and conditions favoring the occurrence of road traffic congestion, the deterioration of urban mobility due to road traffic congestion in the European Union and the queues of road vehicles (moving or stationary columns at intersections, pedestrian crossings, railway level crossings, accidents or road events, etc.). The scientific paper also deals with two case studies on waiting wires. At the end the conclusions related to this research area are drawn and some recommendations are made by the authors regarding the field. The paper also contains an annex in which the 30-minute accessibility by car during peak hours in 2012 and 2019 in other EU cities is presented.
