Abstract
Transport interactions perfectly reflect real spatial interactions and inter-urban relationships. They represent the mobility of passengers, information or goods, including commuter flows, commuting to services, etc.
Delimitation of functional transport regions based on passenger-car traffic flows represents a traditional approach in geography, but has recently been neglected. The article explains why road-network traffic flows should be reconsidered for the purposes of delimiting functional urban areas (FUAs) and demonstrates that delimitation of functional regions based on passenger-car traffic flows is an efficient way corresponding to former approaches to the delimitation of functional urban regions in Slovakia.
This study utilises periodical and well-available road-traffic survey data as of 2010, interpreted in GIS environment.
