It is increasingly challenging for metropolitan areas to be sufficiently accessible in terms of transportation and mobility. European metropolitan areas will be able to learn from each other by utilizing wide-ranging research on accessibility, connectivity and mobility.
Increasing mobility in urban areas requires greater road capacity for which there is little space available. At the same time, citizens are less willing to deal with perceived downsides of more accessibility, such as increased traffic, congestion and air pollution. European metropolitan areas and cities need to develop efficient ways of ensuring they stay connected, by improving parking access, for example, or by using payment systems for inner-city roads.
