Smart Port-Cities of the future will take advantage of the newest IoT technologies to tackle those challenges in a joint fashion from both the city and port side. A specific matter of interest in this work is how to obtain reliable, measurable indicators to establish port-city policies for mutual benefit. This paper proposes an IoT-based software framework, accompanied with a methodology for defining, calculating, and predicting composite indicators that represent real-world phenomena in the context of a Smart Port-City. This paper envisions, develops, and deploys the framework on a real use-case as a practice experiment. The experiment consists of deploying a composite index for monitoring traffic congestion at the port-city interface in Thessaloniki (Greece). Results were aligned with the expectations, validated through nine scenarios, concluding with delivery of a useful tool for interested actors at Smart Port-Cities to work over and build policies upon.<\/jats:p>","DOI":"10.3390\/s20154131","type":"journal-article","created":{"date-parts":[[2020,7,24]],"date-time":"2020-07-24T11:16:35Z","timestamp":1595589395000},"page":"4131","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Framework and Methodology for Establishing Port-City Policies Based on Real-Time Composite Indicators and IoT: A Practical Use-Case"],"prefix":"10.3390","volume":"20","author":[{"given":"Ignacio","family":"Lacalle","sequence":"first","affiliation":[{"name":"Departamento de Comunicaciones, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreu","family":"Belsa","sequence":"additional","affiliation":[{"name":"Departamento de Comunicaciones, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2372-6253","authenticated-orcid":false,"given":"Rafael","family":"Va\u00f1o","sequence":"additional","affiliation":[{"name":"Departamento de Comunicaciones, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos E.","family":"Palau","sequence":"additional","affiliation":[{"name":"Departamento de Comunicaciones, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,24]]},"reference":[{"key":"ref_1","unstructured":"WHO (2020, June 29).
