{"abstract":"Motorcycle taxi-hailing services have emerged as an alternative mode of urban transportation, particularly in traffic-congested cities. In the Philippines, Angkas is among the most widely used motorcycle ride-hailing platforms, yet concerns regarding its reliability, safety, and time efficiency persist. This study examined the perceived reliability of Angkas as a mode of safe transportation among third-year Aircraft Maintenance Technology students at Indiana Aerospace University during the 2024–2025 academic year. A quantitative descriptive research design was employed, and data were collected from 100 students using a structured questionnaire with a four-point Likert scale. Statistical analyses included frequency, rate, weighted mean, and ranking. The findings indicate that respondents generally agreed with the reliability, passenger safety, and time efficiency of Angkas. However, several operational concerns were identified, including booking system issues, fare inconsistencies, trip cancellations, punctuality problems, and noncompliance with traffic regulations. Based on these findings, the study recommends improvements in the booking system, fare transparency, rider accountability, and safety training to enhance the overall reliability of motorcycle ride-hailing services.","abstract_source":"original","authors":["Quenie Espinueva","Karl Angelo Avila","Jiv Levis Gonzaga","Loue Martin Lacea","Jhovie Lapiz","Amaze Prietos","Michael John Ranara","Vince Jhenon Retiza","John Sandoval","John Paulo Solon","Kimberly Cui-Toring","Eugene Toring","Jhoselle Tus"],"date":"2026-02-16","doi":"10.70838/jasaam.010406","id":7190,"issue":4,"journal":{"issn":"3062-4460","name":"Journal of Advanced Studies in Aviation, Aerospace, and Management"},"pdf_sha256":"6b0042945325a4118ef25cc5c8bd08cdb09ab479e62dbb485c80c9b6117e19dd","schema":"scimatic-article/1","title":"Assessing the Reliability of Angkas as a Mode of Safe Transportation Among University Students","volume":1}
