1 Current System Summary
Currently there is a big problem in the parking of vehicles in Hood College, as the staff
and student search for parking spaces manually. The students just drive to the school
compound and search for any available parking space in parking lot. For the staff, they
have specific assigned parking slot in various departments. But, when it comes to a point
where they require to go to a different department, they have to go around the parking
space trying to identify any free parking slot. This becomes quite inconvenient as it is
time wasting in the searching process; whereas not all parking slots are occupied. The
staff, the students and visitors have different types of gate passes this helps in restriction
of entry in various gates. Some gates are only restricted to staff and other the visitors are
not allowed to go through.
1.1 Background
Based on the current system the main purpose is the restriction of entrance in various
section of the school. This helps to enhance security within the school especially in the
areas strictly designated for the staff only. Also the visitors cannot go to any area in the
school. They have some specific places they should go. But if there is a necessity to go to
certain areas in the school and their gate passes do not allow going to such places then
special gate passes are given to the user in need. The current system is not effective. This
is because the vehicles are allowed into the college compound but there is no specific
way in managing the vehicles in the car parks. A system that helps in the managing of
vehicle parking space was found to be useful in the college (Zhdanov, Korolev and
Utemov, 2010).
1.2 System Objectives and Current Functionality
The current functionality of the system could be termed as an incomplete system. The
restriction of vehicle users to access various areas within the college. The objective of the
system is to enhance security and ensure than ensure an equivalent distribution of vehicle
in different parking spaces within the college. This is system is achieved by use of
sensors in the gate passes.
Despite the objectives of the current system, the number of students, staff and visitors
have increased. This has resulted to an increase in the number of vehicles in Hood
College. The large number of vehicles in the college compound has resulted to poor
parking behavior where vehicles are even parked on the roads even when the parking
slots are not fully occupied. This is wasting of resources and the vehicles interfere with
the pedestrians on the college roads.

1.1 Current Methods and Procedures
DFD
Fig 1 data flow diagram.
The students, staff and visitors are the users of the current system.
A user is required to have valid gate pass according the user’s category. This categories
include: staff, student or visitor.
The gate pass has a chip that gives information about the areas a specific user is granted
access.
This gate pass will determine if the users has access or not to go to a specific area in the
college.
Once the user has access then he/she will manually find for a place to park the vehicle.
