The document describes a study that used linear regression to model urban growth in Irbid, Jordan from 2002-2013. It aimed to determine the relationship between growth in built-up area and factors like population, density, building permits, and construction costs. The best variable to represent growth was found to be the total number of building permits, which correlated negatively with increases in population and density. Urban growth occurred primarily to the north and east of the city. Population increased 22% while built-up area rose 70% during the study period.

Abstract
This study applied leaner regression to model urban growth in Irbid to discover the
relationship between urban growth and the driving forces. We will use cross section
from 2002 to 2013.There are many factors affect the new building construction
growth in the city which leads to urban growth. What we will study in this paper is.
A. Find the main 'Y' that represents the growth of built up area using leaner
regressionmodel.
The probable depending Y's are:
 Total Number of Building permits each year
 Total new Building area each year
 Total building construction price each year
 Building construction price per square meter.
B. The percentage ofgrowth in Irbid city from 2004 to 2013.
 Population and density growth.
 Built up area "new building construction".
C. Using GIS to study the direction of growthin Irbid.
1. INTRODUCTION
Due to the high concentration of population in urban areas there is a rapid growth in
urban. Urban development has often the meaning of urban growth. Thus, the rapid
change in the pattern of urban within a short period of time can be seen. On the
other hand, understanding the mechanisms of urban development is crucial for
planning and urban management in order to achieve sustainable urban development.
Therefore, I will develop a model for study the urban growth. The modeling aims to
discover the relationship between urban growth regarding to the increase in the built
up area and population and density growth in Irbid.

3. THE DATA FOR THE STUDY AREA
In this research the process of urban growth is modeled for the city of Irbid. Irbid is
the 2nd largest city in population in Jordan according to statistics provided by the
Statistical Center of Jordan, the city of Irbid, with an area of about 1,572 square
kilometers and a population of about 1.16 million. It is the city with the highest
density in Jordan. The city of Irbid, is located in the north of Jordan 320 35, to 350
48, .In this study, the satellite images shows the built up area of Irbid in the years
2004, 2008, 2011 and 2013 are used.

5. 3. YTotal number of Building permitswith Xpopulation +Xdensity.
In research on how population growth affects built up area. There is a strong relation
how greater population size and density affect the growth of total Number of Building
permits each year.
The relationship between population and density growth and the total Number of
Building permits each year is negatively correlated.
What we found that the number of new building permits decrease while the
population and the built up area increased and that’s related to many reason
1- Now they built building with from 7 to 21 or more flats per building.
2- Single building like villas is less.
3- We have new malls building which area is very big.
 There is no correlation between the growth of population size and density
with the total New Building area each year.
 There is no correlation between the growth of population size and density
with the total new building construction price.
 There is no correlation between the growth of population size and density
with the building construction price per square meter

D. Using GIS to study the direction of growthin Irbid.
In this paper, four satellite images of Ibid, which were taken in2004, 2008, 2012 and 2014,
are used as the base information layers to study the changes in urban growth direction of
the city of Irbid. The direction of the urban growth for the city of Irbid is to the north
toward Amman the capital of Jordan, the other direction or growth is in the direction of
Petra Street and in the center of the city which made the city very crowded. In a period of
twelve years the increase of population is 22% 211600 from 2002 with total population of
1162300 person is clear in the GIS photos. The increase in the built up area from 2002 to
2013 is 7300385 m2 which represent 70% increase from 2002.

11. 6. IMPLEMENTATION AND RESULT
In the first step of research, was obtained the variables. Then we collect the data
that is needed, the next step was by using linear regression model to find the best x's
and Y's that represent the urban growth of Irbid city regarding to the city growth.
Then we defined the direction of growth in Irbid by using GIS Arial views. Finally,
the simulated image of the urban growth was generated.
7. CONCLUSION
In this paper, at the beginning of the study I thought that the new building area or
the price are one of the main element that effect the growth and can represent Y in a
good way but after I worked on the SPSS I found out that they are not effective.
Also the price per m2 was the highest in the year's 2008, 2009, and 2010 while the
built up expansion and the new building growth was the highest in these three years
which show us that the price factor is not important and doesn’t affect the growth.
In the other hand the number of new building permits represents the best Y and
represents the growth with successful results. the number of new building permits
is decreasing from 2002 until 2013 by 14% while the growth is rapidly increasing
and that’s related to the decrease of the multi flat and level buildings, the decrease
of the villas and the increase of the huge building with thousands of m2 area like the
hypermarkets and the huge malls and shopping center which appear in the past
years. But I think there will be a limit then the number of permits will start to
increase again.
The satellite images of Irbid are used as the base information layers to study the
direction of the urban growth which is mainly to the north of Irbid in the direction
to Amman and to the east which appear after al Petra Street constructed. In my
opinion it's very important to study the urban growth, the element that affects it and
the direction of growth to be able to estimate the future expansion and its directions
to design the best future urban solutions.
