They also provide access to individual plots such as farms and homes, usually these roads are unpaved or poorly paved. Collector roads: these connect the more lightlypopulated rural areas into the secondary and primary road network. Generally road networks comprise of three classes of roads: - Major arterial: These connect main towns and governorates, they carry mostly long- distance traffic that is either generated in the towns or collected from the rural areas by the secondary and local roads - Minor arterial: these connect small towns and groups of villages and link these areas into the primary road network. Travel patterns within the central part of Dhi-Qar are focused on Nasiriyah which provides strong links and good services between Nasiriyah and the other District centers, Al Shatra, Al Rifaai, Suk Shoyukh and Al Jabayish, which are lack good services locally. Transportation provides the means to travel for purposes of employment, exploration, personal fulfillment and is a necessary condition for human activities, such as commerce, recreation, and defense.
1 Introduction The purpose of transportation is to provide a mechanism for the exchange of goods, information, and to support economic improvements for society. On the basis of that proposed to add new roads to change path of external - external trips and also add new bridges to get rid of the congestion that appeared in the city center.

The network is used to assess the flow of the current traffic network patterns through several programs such as the (TransCad, GPS, GIS) so collecting different types of data, such as (Traffic volumes and free flow speed) using a device (MSSS), field surveys is done for the work of large-scale map road network.the results of the evaluation showed that most of the roads in the city have a level of service type (B), as the network showed service-level type (F) at which the vehicle relative to the road capacity (v/c) is greater than one in the city center, such as (Habboubi Street, Nasir bridge, Sumer Street, etc.) as illustrated in analysis map. Network in the city center suffers congestion, particularly during peak hours simply because of the existence of vitality centers (educational, commercial and government). AL-Nasiriyah is one of the highly congested urban centers within Dhi-Qar province. Transportation is an essential element for the development of countries economically, socially, and culturally.
