In the developing countries, urban areas commonly suffer from several cases of urban sprawling leading to the decline of accessible liveability so the ideal concepts of public transport (bus, TRAM, BRT, LRT, monorail and MRT) had been introduced to provide the accessibility with the reduced time of trip consumption while the public transport network itself needs to be well connected. Particularly, a concept of the urban rail public transport (TRAM) infrastructure principally focused on effective reachability and tandemly with mass transit concepts as the trip proposal indicator was perceived in order to visualize the urban public transport accessibility index (TPAI) that usefully supports a non – driven virtualization. The contribution of this work was to purposively define the changes in the accessibility of future rail transit network investment plan. Besides, the evaluation was attentively performed on both unimodal and multimodal transports to investigate the urban mobility performance for the whole public transit networks, also a comparative feeder-bus function was considered. The accessibility of the responsive buffer station was mentioned as part of the creative urban methods such as transit oriented development (TOD). Explicitly, research was computed altogether via the objective-based walkability optimization model and a densely district inhabitant technique (DID) in order to interpret the effective grid locations. Notably, this data analysis disclosed the mechanics of public transportation. As a results, the developed models elaborately described the relationships within the city transport networks, accessibility index, the modes of transport (included walk, bus and TRAM), the scale intensity, and the policies trends as the key factors to achieve the ideal concept for those urban rail public transport plans as a primary transport mode. Above all, the models effectively provided the supporting data for the urban plan guideline and the measurement criteria for an urban rail public transportation project.
