Travel requests are collected over a two-month period and consist of origin-destination flows between stations operated by the Belgian national railway company in 2016. The Louvain method is applied to detect communities of tightly-connected stations. Results show the influence of both the urban and network structures on the spatial organization of the clusters. We also further discuss the implications of the observed temporal and regional variations of these clusters for transportation travel demand and planning.<\/jats:p>","DOI":"10.3390\/ijgi5110216","type":"journal-article","created":{"date-parts":[[2016,11,15]],"date-time":"2016-11-15T10:25:31Z","timestamp":1479205531000},"page":"216","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Belgium through the Lens of Rail Travel Requests: Does Geography Still Matter?"],"prefix":"10.3390","volume":"5","author":[{"given":"Jonathan","family":"Jones","sequence":"first","affiliation":[{"name":"Center for Operations Research and Econometrics, Universit\u00e9 catholique de Louvain, Voie du Roman Pays 34, 1348 Louvain-la-Neuve, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christophe","family":"Cloquet","sequence":"additional","affiliation":[{"name":"Poppy, rue Van Bortonne 7, 1090 Bruxelles, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arnaud","family":"Adam","sequence":"additional","affiliation":[{"name":"Center for Operations Research and Econometrics, Universit\u00e9 catholique de Louvain, Voie du Roman Pays 34, 1348 Louvain-la-Neuve, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adeline","family":"Decuyper","sequence":"additional","affiliation":[{"name":"Center for Operations Research and Econometrics, Universit\u00e9 catholique de Louvain, Voie du Roman Pays 34, 1348 Louvain-la-Neuve, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Isabelle","family":"Thomas","sequence":"additional","affiliation":[{"name":"Center for Operations Research and Econometrics, Universit\u00e9 catholique de Louvain, Voie du Roman Pays 34, 1348 Louvain-la-Neuve, Belgium"},{"name":"F.N.R.S.
