The factors affecting respondents to choose the transportation mode options are mode availability, travel time and cost. The probabilities of transportation mode chosen are motorcycle (49.9%), para-transit (36.5%), private car (12%), and taxi (1.7%), respectively. Arranging bus transit will decrease 18-19% private vehicle, and improve most of gateway road performance.
