-# 2021-193 User-friendly enhanced machine learning-based railway management system
-
-User-friendly enhanced machine learning-based railway management system
-
-**Main objective**
-Through this project, hope to develop the enhanced and user-friendly solutions for contributing the Railway service in Sri Lanka. We researched more about the railway passenger’s common problems and hope to develop the suitable solutions as user friendly for those problems.
-
-**Main Research questions**
-Some travelers do not know much about trains and attractive destinations to choose from. At present, there is no application to guide tourists to the tourist destinations of their choice. Therefore passenger needs to spend more time for find the visiting places. It may cause them to waste their time which can spend on their enjoyment.
-Passengers cannot get information about train stopping station, facilities, and the time duration of the trip. Railway passengers cannot get the needful and exact information about their visiting places.
-When passengers booking the ticket they cannot be booked which seat they want and there is no process to suggest the most preferred seating place. It may cause personal conflicts between closely seated passengers due to differences of personal interest.
-Difficult to find the visitor's attracted places that are located near the trip route. Therefore unpopular attractions are missed by many travelers. It is affected by traveling passengers and the tourism industry.
