Introduction

One of the most challenging and complicated issues in city management in the present decade for Bangladesh is the traffic problem. This traffic congestion problem in Bangladesh are increasing at an alarming rate. With a view to saving Dhaka from the unbearable traffic jam, metro rail project has finally completed. It will save thousands of work hours by reducing traffic jams. But traditional ticketing model of passengers buying a ticket before being able to travel on the transport network leading to long lines during peak periods as people wait in line for tickets. If some of this ticket service could be provided online this will decrease the unnecessary waiting in long line as well as ensures a smooth buying process.

1.1 Purpose

Appendix A: Glossary

SRS: A software requirements specification (SRS) is a detailed description of a software system that will be created. The software requirements specification specifies functional and non-functional requirements, as well as a collection of use cases that explain the user interactions that the program must allow for ideal interaction.
