In order to check the wider applicability of our proposed Apps, we have tested Haversine modules for long and short distances, and the Spherical Law of Cosine and Pythagoras Theorem to compute shorter distances. These tested examples are presented in the Appendices A and B for all the four quadrants of the globe (Figure 3). These results justify that our proposed Apps are applicable for global, regional and local scales (Appendices B and C). Though several Apps are in use in Nepal, none is designed to track the RBT system as of today.
Four types of users can use our proposed Transit Tracker Apps. These users include: 1) Normal user; 2) Drivers; 3) Administrator(s); and 4) Sub-administrator(s). This application can be accessed by mobile application and web application.
