Abstract
Our system it develops, markets and operates the mobile app, which allows consumers
with smartphones to submit a trip request which is then routed to drivers who use their own cars
or drive company cars.
To passengers, our system is essentially synonymous with taxis, and to drivers, it’s
basically a referral service. The Android, iOS and Windows Phone app connects riders with
drivers using their phone’s GPS capabilities, letting both parties know one another’s location
and removing the question of when the ride will actually arrive. In addition, the tech company
also processes all payments involved, charging the passenger’s credit card, and direct depositing
the remaining money into the driver’s account, all in the background and completely cashless.
The System Architect build based on the most modern technologies and concepts from
the idea of using smartphones to the software architect of SOA (Service-Oriented Architecture)
Considering the new and modern software methodologies and concepts we chose to use
the Unified Process (UP) model to construct our system. Which gives us the most flexibility to
develop our system and finalize software process stages.
Finally we consider of using the most productivity and capability tools for development
our system including (Databases, Software, User interfaces and documentation).

Project planning
1- Introduction the idea on E-Taxi is evolving the way the world moves. By seamlessly connecting
passengers to drivers through our apps, we make cities more accessible, opening up more
possibilities for passenger and more business for drivers , Get a reliable ride in minutes with the
E-Taxi app, no reservations or waiting in taxi lines, from low-cost to premium, every ride option
feels like an upgrade to the everyday. Create your account using a credit card or PayPal, and your
fare will be charged automatically at the end of your ride. You can also pay with cash in select
cities.
1.1 Project objectives as the ideas, thoughts and product designs began to accumulate our main
objective to provide you, the customer, with a safe, reliable and easy taxi service, still proved to
be the focal point. We believe that in today’s day and age, one should have confidence that their
taxi will arrive on time and that you will not be over charged, and for these reasons,we introduced
the much needed transparency
1.2 Project Stack holders
When we come to the designing of the information system, a term often make us think; who are
Stakeholders? So let us define this with the formal definition and it goes like this.
‘Any person whohas interests inan existingor proposed informationsystem.Stakeholders may include
both technical and non-technical workers. They also may be the internal ones or may be the external
one.’
So I think the idea of ‘Who are stakeholders?’ has come to the mind. In building the information system
the system owners, system users, system designers, system builders and all of the above system analysts
and the project managers all these are commonly known as the stakeholders. Whatever their roles in an
organization are it doesn’t matter, all the thing common in them are that, they are information workers.
Let us explore a little deep to the stakeholders:

System owners: An information system’s sponsor and executive advocate usually
responsible for funding the project of development, operating and maintaining the
information system.
In this system the system owners are the companies who intend to work on electronic
taxies field.
System users: Is the customer who will use the system or is affected by an information
system on a regular basis – capturing, validating, entering, responding to, storing, and
exchanging data and information.
In this system the system Users classified as internal and external users
A- Internal System users
1- Technical and professional staffs which are the staff will operate and maintain system
events like Driver registration approval block users or Drivers
2- Supervisors, Middle managers and executive managers which are the staff of managers
need generate reports from the system like system cash flow
B- External System User
1- Customers any external user have an registration ID will be customer and both of trip
requester or driver are customers on our system
System Designers: a technical specialist who translates system users’ business
requirements and constraints into technical solution. She or he designs the computer
databases, inputs, outputs, screens, networks, and software that will meet the system
users’ requirements.
A- Database Architect (DBA) creates and manages large and expansive electronic
databases to store and organize vast amounts of data. This is a highly skilled profession

1.5 Problem analysis
Risks involved in existing system.
1.6 Feasibility study:
The objective is to determine whether or not the proposed system is feasible. The three
tests of feasibility have been carried out:
A- Technical feasibility
B- Economic feasibility
C- Operational Feasibility
Technical feasibility: In technical feasibility one has to test whether the proposed
system can be developed using the existing technology.
It is a study of resource availability that may affect the ability to achieve an acceptable
system.
This evaluation determines whether the technology needed for the proposed system is
available or not.
As the available technical resources (such as Microsoft SQL server, Microsoft
ASP.NET… etc.) are so satisfactory for the scope of the proposed system, the proposed
system considered technically feasible.
15. -14-
Economic feasibility: The costs and benefits associated with the proposed system
compared and the project is economically feasible if tangible or intangible benefits out
weight cost.
As the proposed system development costs are significant as estimated so the system
proposed considered feasible economically.
Operational Feasibility: It is a standard that ensures interoperability without stifling
competition and innovation among users, to the benefit of the public both in terms of
cost and service quality. It is mainly related to human organizations and political
aspects. In operational feasibility the following points are studded:
- The impact of the changes would be made by the new system.
- The organization structure that might be disturbed by functioning the new system.
- The gap between the skills that the staff of the organization /s that would use the system
and the skills needed by the system to operate appropriately.
The system is operationally feasible as it very easy for the End users to operate it, its
functioning disturbs no other organization structures, and it have no undesired changes
to be made by its functionality.
1.7 The system Development life cycle:
System development process: a set of activities, methods, best practices, deliverables, and
automated tools that stakeholders use to develop and maintain information systems and software.
System Development Process Overview:
The systems development life cycle (SDLC), also referred to as the application
development life-cycle, is a term used in systems engineering, information systems and software
16. -15-
engineering to describe a process for planning, creating, testing, and deploying an information
system.[1] The systems development life-cycle concept applies to a range of hardware and
software configurations, as a system can be composed of hardware only, software only, or a
combination of both
Figure (1.2)
Systems development life cycle
System Planning: the initial planning for a project to define initial business scope,
goals, schedule, and budget.
System analysis: the study of a business problem domain to recommend
improvements and specify the business requirements and priorities for the solution.
System design: the specification or construction of a technical, computer-based
solution for the business requirements identified in a system analysis.
System implementation: the construction, installation, testing, and delivery of a
system into production.

Requirements
Requirements analysis
The requirement analysis phase is the most important phase along the phases of the information
system development process in this system and any other information system. Inadequate
attention to that phase always results in user disagreements and dissatisfaction of the system or
some functions of the system which would be so costly to get over.
There is a 7 common fact finding techniques for gathering user requirements which are:
bservation of work environment
Each technique has its advantages and disadvantages. It is never better to consider one of them is
the best technique while the efficiency of the used technique differs from a system to another
depending on the nature of the system and the working environment.
1- Sampling of existing documentation, forms and databases.
The following screen shots were collected (only sample of the gathered screen shots
23. -22-
2- Observation of work environment
The advantages of this technique are:
Data gathered based on observation can be reliable.
24. -23-
The system analyst is able to see exactly what is being done.
Observation is relatively inexpensive compared with other techniques.
Because of the important advantages of this technique it has been used along with other used
techniques for fact finding techniques for this project.
3- Interviews
The type of interview used is the unstructured open-end interview.
This method was choosing because of the nature of the interviewees (students’ doctors and
heads of departments).
3.1 Functional requirements: Functional requirements are a description of activities and
services a system must provide.
ored data
The functional requirement of the proposed system according to the specified scope can be
divided to data requirements, process requirements and interface requirements.
First: data requirements as inputs and outputs
The system must handle the following inputs:
1- Allow user to enter its personal data like first name , last name , mobile number ,
addresses , email to can register on our system
2- Allow user to enter Location through GPS location system atomically or manual through
map
3- Allow user to set it ride target using map
4- Allow user to can evaluate driver if it passenger or evaluate customer if it driver
5- Allow Driver set it availability status
Second: process function all requirements
The main process the system must allow customer ride request and it is request must be service
Third: Interface requirements
25. -24-
The interface should be available for users all the time and they can access it from anywhere.
3.2 Non Functional requirements:
A description of other features, characteristics, and constraints that define a satisfactory system.
• Performance, ease of learning and use, budgets, deadlines, documentation, security, internal
auditing controls
The non-functions requirements of the system are:
- The system should have a user friendly interface which is simple and easy to use and
understand.
- The system should be highly secured.
- The system should have an interface for news.
3.3 System Constraints:
The primary impact of project constraints is the likelihood of delaying the completion of the
project.
There are three types of project constraints:
- Technological
- Resource
- Physical
The technological constraints
Relate to the sequence in which individual project activities must be completed.
26. -25-
Resource constraints
Relate to the lack of adequate resources which may force parallel activities to be performed in
sequence. The consequence of such a change in network relationships is delay in the completion
date of the project.
Physical constraints
Are caused by contractual or environmental conditions.
