In Portugal, after the economic crisis of 2008\u20132013, a significant amount of road assets demand investment in maintenance and rehabilitation. The areas where these actions take place are called work zones. Considering the particularities of these areas, the proposed work aims to identify the main factors that impact the occurrence of work zones crashes. It uses the statistical technique of multinomial logistic regression, applied to official data on road crashes occurred in mainland Portugal, during the period of 2010\u20132015. Usually, multinomial logistic regression models are developed for crash and injury severity. In this work, the feasibility of developing predictive models for crash nature (collision, run off road and running over pedestrians) and for type of person involved in the crash (driver, passenger and pedestrian), considering only one covariate (the number of persons involved in the crash), was studied. For the two predictive models obtained, the variables road environment (urban\/rural), horizontal geometric design (straight\/curve), pavement grip conditions (good\/bad), heavy vehicle involvement, and injury severity (fatalities, serious and slightly injuries), were identified as the preponderant factors in a universe of 230 investigated variables. Results point to an increase of work zone crash probability due to driver actions such as running straight and excessive speed for the prevailing conditions.<\/jats:p>","DOI":"10.3390\/su15032674","type":"journal-article","created":{"date-parts":[[2023,2,2]],"date-time":"2023-02-02T02:21:12Z","timestamp":1675304472000},"page":"2674","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Modelling Road Work Zone Crashes\u2019 Nature and Type of Person Involved Using Multinomial Logistic Regression"],"prefix":"10.3390","volume":"15","author":[{"given":"Adriana","family":"Vieira","sequence":"first","affiliation":[{"name":"Department of Civil Engineering and Architecture, University of Beira Interior, 6200-358 Covilh\u00e3, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5545-892X","authenticated-orcid":false,"given":"Bertha","family":"Santos","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering and Architecture, University of Beira Interior, 6200-358 Covilh\u00e3, Portugal"},{"name":"CERIS, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2072-3188","authenticated-orcid":false,"given":"Lu\u00eds","family":"Picado-Santos","sequence":"additional","affiliation":[{"name":"CERIS, Instituto Superior T\u00e9cnico, Universidade de Lisboa, 1049-001 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,2]]},"reference":[{"key":"ref_1","unstructured":"OECD-ITF (2022, November 09).
