Long-distance trips in a sparsely populated region: The impact of high-speed infrastructures

This paper aims to analyze the different territorial performance of two new high-speed transport infrastructures, a national motorway and a high-speed rail (HSR) line, with an emphasis on their different roles on long-distance trip making, in a peripheral and sparsely populated province of Spain, contributing to the existing limited research on the influence of high-speed transport infrastructures on urban structure and mobility of sparsely populated regions.The paper provides empirical evidence by means of a mobility survey. The analysis of modal split, travel frequencies, and travel purposes allows a better understanding of long-distance mobility patterns and establishes different travel profiles. The study of commuting and discretionary flows shows different levels and types of metropolitan integration depending on the type of connection and on local characteristics.
