This paper addresses the reality of slum housing and its characteristics, drawing on an analytical field study, where it focused on the city of Tebessa. The study showed that about 57% of the messy residences in the city are of the same type of steel that can be settled according to the construction laws in effect. It also showed that the majority of slum dwellers are rural immigrants who live in fragile conditions. In light of these circumstances, the state’s intervention to address this situation came through Law No. 15-08 related to matching buildings and / or completing their completion issued on July 20, 2008. However, the latter witnessed many obstacles and difficulties that prevented the achievement of its goals despite the passage of a full decade since the launch of its application, as the proportion of chaotic housing that was treated in the city did not exceed 28.59%. All of this was mainly due to the reluctance of the population to engage in it in light of the great weakness of the media and oversight role of government authorities, which prompted us urgently to search for viable solutions to this problem in order to achieve sustainable urban development.

From this study on the analysis of the urban transport network of the city of Tébessa using Geographic Information Systems (GIS), it can be seen that the transport network represents one of the most important components of the city. The objective of this study is to highlight the measures to ensure that the network meets the needs of the population in terms of accessibility, identifying black spots and showing the central nodes. (Customs node and amusement park) for the city of Tébessa, which are the two most frequent points of traffic congestion. With the geographic information system software (ArcGIS), a network analysis technique that allows us to define the shortest possible route between two points in order to reduce the distance travelled, to save time and to give and avoid as much as possible the black spots to move more easily in the city, another technique has been used, which is the sphinx software also used to create and analyse the questionnaire destined to the words of the inhabitants of the city to evaluate the road network.The aim is to test the research hypotheses that the transport network represents a major obstacle to traffic through all the problems that the transport network suffers from, such as traffic congestion, narrow roads and deteriorating conditions. The study recommends the creation of new roads and diversions to mitigate the efficiency of the transport network and achieve accessibility throughout the city of Tébessa.
