Analyzing Passengers' Mode Choice Behavior in an Integrated Urban Transport System: Application to BRT System at Ring Road in Greater Cairo

Egypt is actively pursuing sustainable urban mobility through the maximization of mass transit and the implementation of Transit-Oriented Development (TOD). In Greater Cairo, the planned BRT system on the Ring Road represents a significant stride towards achieving these goals. While the BRT forms the backbone, its effectiveness within the broader integrated urban transport system is enhanced by seamless linkages and safe transfers with active mobility modes, specifically Non-Motorized Transport (NMT). This paper employs the Logit calibration of advanced discrete choice models, a robust method for analyzing individual decision-making, to predict passengers' mode choice behavior. Data was collected from individuals across all relevant Ring Road zones in Greater Cairo using a carefully designed Stated Preference (SP) survey, which captured their responses to hypothetical travel scenarios. The empirical findings indicate that socioeconomic factors, particularly income, are powerful determinants of mode choice, with higher-income individuals showing a greater propensity to use private vehicles. However, aligned with trends in developing nations, attributes directly related to service quality and accessibility, such as in-vehicle time, were found to exert a notably greater impact on commuters' mode preferences for public transport options like the BRT.
