This resulted scenario is expected to favor adopting cleaner and flexible modal solutions centered on bicycles and scooters, especially as last-mile options. However, as the use of bicycles has rapidly increased, cyclists have been subject to adverse conditions that may affect their health and safety when cycling in urban areas. Therefore, whereas cities should implement mechanisms to monitor and evaluate adverse conditions in cycling paths, cyclists should have some effective mechanism to visualize the indirect quality of cycling paths, eventually supporting choosing more appropriate routes. Therefore, this article proposes a comprehensive multi-parameter system based on multiple independent subsystems, covering all phases of data collecting, formatting, transmission, and processing related to the monitoring, evaluating, and visualizing the quality of cycling paths in the perspective of adverse conditions that affect cyclist. The formal interactions of all modules are carefully described, as well as implementation and deployment details. Additionally, a case study is considered for a large city in Brazil, demonstrating how the proposed system can be adopted in a real scenario.<\/jats:p>","DOI":"10.3390\/smartcities4030056","type":"journal-article","created":{"date-parts":[[2021,7,25]],"date-time":"2021-07-25T22:07:00Z","timestamp":1627250820000},"page":"1058-1086","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["iBikeSafe: A Multi-Parameter System for Monitoring, Evaluation and Visualization of Cycling Paths in Smart Cities Targeted at Cycling Adverse Conditions"],"prefix":"10.3390","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4285-0006","authenticated-orcid":false,"given":"Franklin","family":"Oliveira","sequence":"first","affiliation":[{"name":"UEFS-PGCC, State University of Feira de Santana, Feira de Santana 44036-900, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3988-8476","authenticated-orcid":false,"given":"Daniel G.","family":"Costa","sequence":"additional","affiliation":[{"name":"UEFS-DTEC, Department of Technology, State University of Feira de Santana, Feira de Santana 44036-900, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1385-5908","authenticated-orcid":false,"given":"Luciana","family":"Lima","sequence":"additional","affiliation":[{"name":"UFRN-DDCA, Department of Demography and Actuarial Science, Federal University of Rio Grande do Norte, Natal 59078-970, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0116-6489","authenticated-orcid":false,"given":"Ivanovitch","family":"Silva","sequence":"additional","affiliation":[{"name":"UFRN-DCA, Department of Computer Engineering and Automation, Federal University of Rio Grande do Norte, Natal 59078-970, Brazil"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"51","DOI":"10.1145\/3416961","article-title":"Toward smart and sustainable cities","volume":"63","author":"Kon","year":"2020","journal-title":"Commun.
