المستخلص: This study aims at investigating the spatial relationship between cars roads and urban land of uses in al Khalis city.The study has revealed the geographical factors like the geographical position and the area which reached 24,696,632 Km2 a plane area of about 45 - 50 meters above the sea level. All those factors played a great role in the planning of the city, the expansion of the roads, then the development of urban transportation network in the city. Moreover, the spatial growth and the expansion came along with the development of the important roads like Baghdad - Kalis - Kirkuk road and the Main street "Al Hussein Street" in the city.The study also revealed the existence of three patterns of roads in the city : organic, radial, and quadric - grid. The grand length of the roads reached 219,446 meters. The grand area of roads reached 3,923,813 m2 in 2013 which forms 15.8 % of the city area.The use of land for transportation service purposes has increased from 0.231022 km2 in 1987 to 3,971,313 km2 in 2013. This represents 16% of the city area which is a small area regarding the international standards that propose that the transportation area should form 25 - 23% of the city area.The study also revealed that there is a relation between travelling, family size and characteristics, ownership of cars, and the family income. Concerning the traffic inside the city, it was found that the maximum traffic of the main entrance during the evening period was 65.7% incoming, whereas the traffic of regional highway junctions registered its highest traffic in Kalis - Kirkuk highway which reached 34.4%.In finding the relation between roads and the change in urban land uses, it was found that the city was horizontally expanded in investing the surrounding and vacant lands, as well as intensive use of lands and expansion towards orchards and breaching estate type uses along with the expansion of the roads. All this caused a fundamental change in urban land uses in Al Khalis City. The study also registered a great development in the urban land uses in the city between 1987 - 2013. When conducting the comparison, it was found that there is a great change in the distribution of lands along with the roads of the city, as well as increasing commercial use from 8% to 36%, industrial use from 5% to 24%, and the service use from 8% to 20%. On the other hand there is a decrease in the residential use from 19% to 16% and agricultural use from 37% to 4% in 2013. This draws the attention on that huge areas of orchards an farms in the city were transformed into other uses due to paving the roads in it as well as the decrease in vacant lands which explains the intensive investment of lands due to competition.The study also proved the role of roads in the functional and architectural structure of the city by the diversity of the values and area of the urban lands according to the type of the street. Competition utilizing the land is more intensive on the main street and its subordinate alleys and decreases near the highway. The main street has more commercial use that reaches 39% while more residential use was on subordinate streets which reached 25%. Service use registered its highest percentage near the main street and the highway. It reached 23% for both. Agricultural use was focused near subordinate streets and reached 6% in the city.The study ended by proving the existence of a positive statistical relation between roads and other variables like functional and architectural structures of the city. This was proved by the use of Chi Square in which it was found that calculated values are more than existing values of the study variables and the type of the street in the city
