Baghdad city depended on the private auto in transport and this led to great problems with increasing congestion and traffic problems. Existing public transport suffers from poor accessibility to opportunities which is considered the main existing problem. The local agency decided to construct Baghdad Elevated Train as one of the keys to solve this problem and decrease congestion. This study aims to discuss the changes that the installing of the planned train line could make, by using the Geographical Information System (GIS) to model the transportation networks (sidewalks, public transport network, and the planned elevated train) for two scenarios, first for the current public transport network and second for the long-term situation of the adding of the planned train, furthermore, to find the coverage area for each station and determine the population can be served for each station depending on the census of the zones for the year 2020. The modeled network databases were used to create the closest facility between the centroid of the 43 zones and the selected facilities (Commercial, Educational, Governmental, and Hospitals). The results revealed that the additional service of the train reduced the travel time between Al-Sadr City to four destinations selected for the mentioned facilities by the following percentages (62%, 40%, 46%, and 65%) respectively. Moreover, the population coverage stated that stations 8, 9, and 10 are the most populated.

Laboratory study for the use of recycled foundry sand to improve the performance of asphalt concrete mixture by replacement fine aggregate by waste foundry sand substitute for normal sand was conducted. The experimental work conducted for (4) different proportions (5, 15, 20 and 25)% as fine aggregate. (35) samples was prepared to examine the Marshall stability and flow and moisture damage for asphalt mixture. The obtained results indicate an increase of strength (IDT) for all mixtures than control mixture and higher resist to moisture damage with mixture has(FS (#50).The results showed improvement in behavior in terms of workability and durability and resistance.

In recent works on the Internet of Vehicles, "intelligent" and "sustainable" have been the significant in the case of transportation. Maintaining sustainability is always a challenge. Sustainability can be achieved not only by the use of pollution-free vehicular systems, but also by maintenance of road traffic safety or prevention of accidents or collisions. Quantifying the sustainability of urban transport is important as evidenced by a growing number of studies to measure sustainability in transportation. This paper dealt with the challenge of measuring transport sustainability based on the long environmental and safety indicators. To overcome the issue of using too many indicators for evaluation, this paper develops a method for obtaining a composite transport sustainability index for limited sources and time for collecting data. Seven sustainability indicators relevant to urban transport which deal with environmental and social (safety) aspects were selected depending on available data. The indicators were integrated to environmental, social (safety) sub-indices and then to a composite index, in a way that overcomes the limitations on normalization, weighting and aggregation. It is an attempt to quantify transport sustainability for arterials streets within the Hilla network which provides information about current situation of urban transport in different parts of the city. The value of I CST (composite index of transport sustainability) for main arterials at Hilla city (as case study) equal to 0.648, 0.542 and 0.462 for 40 th , 60 th and 80 th streets respectively. The value I CST is the highest at 40th street (inner Hilla citythe best case) and the lowest at 80th street (outer Hilla the worst case).

As a result of the development in Iraq and the reconstruction of the different buildings, there are construction residues that be assembled in a randomized area of cities where these residues occupy a large area of residential or agricultural areas and pose a danger to the environment and humans, so there has become pressing need to study the environmental impact of construction waste materials and how to recycle and use them in the construction industry in a manner that helps to preserve the environment from pollution and conservation of its natural resources. This investigation includes the production of high performance lightweight concrete sustainable building units containing crushed brick clay resulting from the demolition waste and reconstructive of buildings and manufacture artificial aggregate from waste materials, as coarse lightweight aggregate. These units are features by thermal insulation and lightweight, in addition they are an environmental friendly have low price, which can be used in the implementation of low cost buildings. Two High performance lightweight aggregate concrete mixes were produced, the first concrete mix containing crushed clay brick (mix MBR), and the second concrete mix containing artificial LWA (mix MAR) as coarse LWA. These concrete mixes were used to produce concrete masonry unites (CMUs). High performance lightweight concrete mix containing crushed brick clay has oven dried density of 1930 kg / m 3 , thermal conductivity of 1.0849 W / (m. K), and compressive strength of 41 N/ mm 2 , while concrete mix containing artificial aggregate has oven dried density of 1828 kg/m 3 , thermal conductivity of 0.9278 W/(m.K), and compressive strength of 47 N/mm 2. Two geometrical forms of CMUs with dimensions of 200×200×400 mm were produced, the first one contains spaces less than 25% and the other geometric form contains polystyrene insulation materials. Numerous laboratory tests were carried out on the produced CMUs including, water absorption, density, and compressive strength. The results indicate that these units conforms Iraqi standard requirements No.1077\1987.
