This is progressively continuing in the developed countries. A comparable shift is expected in developing nations; however, empirical studies remain limited, especially in areas where AVs have not yet been deployed. This study investigates the willingness to adopt AVs in a developing city where AVs have not been deployed yet. A comprehensive travel behavior questionnaire was conducted among local commuters in Alexandria, Egypt, to identify the influential variables affecting AV choice. The well-known machine learning classifier, Extreme Gradient Boosting (XGB), was employed to develop a forecasting model, which indicated a notable accuracy. The results indicated that trip cost was the most influential feature. On the other hand, there is a considerable level of mode captivity, since most travelers prefer to remain with their current mode, regardless of the effects of other variables. A significant share of travelers expressed concerns about shifting to AVs due to safety worries associated with the travel behavior of other transportation modes\u2019 commuters. The analysis provides nuanced perspectives on the variables promoting modal shift toward the AVs, supporting future policies for smart urban mobility.<\/jats:p>","DOI":"10.3390\/systems14010045","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T16:08:00Z","timestamp":1767197280000},"page":"45","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Investigating User Acceptance of Autonomous Vehicles in Developing Cities Using Machine Learning: Lessons from Alexandria, Egypt"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8665-2082","authenticated-orcid":false,"given":"Sherif","family":"Shokry","sequence":"first","affiliation":[{"name":"The Center of Road Traffic Safety, Naif Arab University for Security Sciences, Riyadh 11452, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4041-932X","authenticated-orcid":false,"given":"Ahmed Mahmoud","family":"Darwish","sequence":"additional","affiliation":[{"name":"Department of Transportation Engineering, Faculty of Engineering, Alexandria University, Alexandria 21533, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hazem Mohamed","family":"Darwish","sequence":"additional","affiliation":[{"name":"Civil Engineering Department, Faculty of Engineering, Alexandria University, Alexandria 21533, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omar Elsnossy","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Port Said University, Port Said 42526, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1701-0411","authenticated-orcid":false,"given":"Maged","family":"Zagow","sequence":"additional","affiliation":[{"name":"Department of Architecture Engineering, Faculty of Engineering, Tanta University, Tanta 31527, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marwa","family":"Elbany","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering, Port Said University, Port Said 42526, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9176-2956","authenticated-orcid":false,"given":"Usama Elrawy","family":"Shahdah","sequence":"additional","affiliation":[{"name":"Public Works Engineering Department, Faculty of Engineering, Mansoura University, Mansoura 35516, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Qin, H., Yu, B., and Zhang, Y.
