ABSTRACT
Elf is one of the leading transportation service providers in Garut, having earned a strong reputation for its superior reliability and Known for its cheap fleet.
Elf is the main choice of the people of Garut for daily travel and travel between villages and cities.
To keep up with technological developments.
Elf has integrated its services into a mobile platform, which allows people, including those in remote areas, to easily access information related to departure schedules.
However, there are still significant challenges related to access to information, especially schedules, routes, and tariffs, which currently still rely on conventional methods that are often inaccurate.
This research aims to design an Elf transportation information system that is integrated with a mobile platform using the waterfall method.
This approach includes several stages, ranging from needs analysis, system design, implementation, to testing.
The resulting system is expected to provide important features such as vehicle profile information, routes, travel schedules, and user feedback mechanisms.
With this integrated information system, it is hoped that it can improve Elf's operational efficiency and provide a better experience for users.
A user survey will be conducted at the bus terminal to gather feedback, in order to tailor the app's features to their needs.
The implementation of this system is expected to be an effective solution to improve the quality of transportation services in Garut.
