This study chiefly examines the probability of private car and transport network vehicle service (TNVS) users shifting to the Metro Manila Bus Rapid Transit (BRT)-Line 1 system along the Quezon Avenue-España Boulevard corridor given a range of time and cost savings. Chosen respondents are those who ply any portion of the corridor at least once a week using a private car, TNVS, or both. Results indicate that female respondents or non-working respondents generally have higher probabilities of shifting to the BRT than their counterparts who are male or working, respectively. Income, age, car ownership, frequency of use of private cars or TNVS, travel distance, and travel time can mainly be correlated with the respondents' propensities to shift. Based on the results of this study, general policy recommendations include a segmented fare scheme and a special consideration for women in the design of the service.
