Abstract. The Point to Point Bus system (P2P) is a relatively new transportation alternative available in selected areas in Metro Manila and other provinces nearby. New routes are continuously added to cater to the ever-increasing demand of the commuting public to avoid wasting time in heavy traffic and to provide alternatives to the inconvenient metro trains. This paper presents a methodology for the identification of potential sites of additional routes for P2P Premium Bus Service in Metro Manila. Trip generation, trip attraction, and friction factor were determined to show trip distribution using gravity model. A raster-based approach of gravity model was conducted to disaggregate zonal data into discrete and continuous trip distribution values. Through the generated trip distribution values, site suitability was conducted to identify origin and destination of routes, primarily the major malls. Using network analysis, 14 new routes were identified by connecting suitable sites for P2P Premium Bus Service routes.
