1. Introduction

In United States the toll gate payment requires more manual work. Toll App is an application

which enables automatic payment for the Toll gate. Toll gates are created as virtual geo-fences using

Google map and the cost of crossing the fence is defined. The user is tracked via his GPS enabled device

and the payment is made automatically from his credits purchased.

1.1 Methodology

The Rational Unified Process brings together elements from all of the generic process models,

supports iteration and illustrates good practice in specification and design. The RUP is normally described

from three perspectives:

A dynamic perspective that shows the phases of the model over time

A static perspective that shows the process activities that are enacted

A practice perspective that suggests good practices to be used during the process

Inception

The goal of the inception phase is to establish a business case for the system. Identifying all

external entities that will interact with the system and defining these interactions. This information is used

to assess the contribution of system to business.

Elaboration

The goals of the elaboration phase are to develop an understanding of the problem domain,

establish an architectural framework, develop project plan and identify key project risks.

Construction

This phase is concerned with system design, programming and testing. Parts of the system are

developed in parallel and integrated during this phase.

Transition

This is the final phase of RUP and is concerned with moving the system from the development

community to the user community and making it work in real environment.

1.2 Purpose

Toll App is a mobile application developed for automatic and easy payment in Toll gates. Toll

App is a useful and convenient application that spares you the trouble of stopping your vehicle and makes

the payment in Toll gate. This application helps people to automatically pay their charge while crossing

toll fences. The application which we develop here uses state of the art technology to track user’s location

accurately and secure payment.

1.3 Scope

There are two basic users – Administrator, US Peoples, who drive the vehicle across the States.

Administrator has an ability to manage geo fences using Google map.

Administrator has the ability to provide the notification message to the logged users via webpage.

Users should provide their identities in the Toll App website.

Users should download the Android application from Google play and connect to the server by

using his credentials provided by the administrator.

Users can be able to purchase credits using credit cards/pay pal account/debit card.

Users can view his history about the payments made.

Users can receive notification about the charges when he crosses the fences that created in

Google map.

The SRS will include two sections, namely:

Overall Description

This section will describe major components of the system, interconnections, and external

interfaces.

Specific Requirements

This section will describe the functions of actors, their roles in the system and the constraints

faced by the system.

2. Overall Descriptions 2.1 Product Perspective

The Toll App is available for use by the administrator and the user. The administrator and users

will use the webpage as a front end. Toll App mobile application is available for the user. The browser

goes through an http server. Application server manages the connection between the front end and

backend, all types of information and data, that are necessary for the users are stored in MS SQL Server.
