Estimating Base Saturation Flow Rate for Selected Signalized Intersections in Al-Najaf City

The correct saturation flow rates for the specific circumstances must be used to calculate delays and the level of Service at intersections. As a result of a lack of local data, practitioners would often use default values from overseas software developers. Base saturation flow rate is an important factor for timing traffic signals. Despite the 1, 900 pc/h/ln number suggested by the Highway Capacity Manual (HCM), the base saturation flow rate differs from city to city, dependent on the local driving habits and traffic conditions. As a result, it's crucial to estimate, given the local climate. As a result, erroneous decisions may be made that have incorrect results. This study attempts to estimate the base saturation flow rate in Al-Najaf City. The following situations were observed: Turning movement (through or right); Gradient (Up and down); Number of through lanes; and Speed limit (60 and 80 km/h). The mean headway from a total of 9931 through moving vehicles from 187 lineups was calculated to be 1.55. The basic saturation flow rate was therefore determined to be 2, 323 pc/h/ln. This result is substantially higher than the 1, 900 pc/h/ln proposed by the HCM, but it is comparable to results from other nations with similar traffic conditions and driving habits. The results show significant differences between the saturation flow rates when the conditions of the movements are different in terms of the above characteristics. Recommendations are made regarding the most appropriate values to use under different conditions

Evaluation and Analysis of Al-Matar Road (Ring Road) In Al- Najaf City

Assessing and comprehending the degree of service rendered by diverse transportation infrastructures is of utmost significance for individuals responsible for designing and managing traffic networks. The current study was carried out on the principal urban road named Al-Matar, situated in Al-Najaf City. The methodology involves collecting data regarding the geographic location and implementing traffic surveys, which can include various metrics, including traffic volume, travel time, and free flow speed. The Highway Capacity Manual (HCM) has been designated for evaluating the functional effectiveness of various urban streets. The research findings indicate that the time of travel could be mainly used as an indicator for measuring performance during peak hours or off-peak hours. Additionally, the study observed that U-turns have a significant influence on both travel time and speed. The results indicated the crucial effect of U-turn on the city's operational performance on the ring road

Evaluating Urban Streets and Public Transportation in Karbala City Using GIS

Because of the privilege of the city of Karbala with its religious character, this city has become a destination for all visitors from all cities of the world; as a consequence, there are now more people living in Karbala, which has increased the number of vehicles on the road and, consequently, the amount of traffic congestion. In this study, the degrees of public transportation service in the city of Karbala as well as the urban road network, were assessed using GIS. The collected data include the number of nodes, links, and the total length of Karbala's urban road network using a GIS program and traffic composition (bus and minibus). Then, a set of coefficients for evaluating the urban road network was calculated) β- Index, α- Index, γ- Index, η- Index and GTP- Index), After determining the percentage of buses and minibusses, it became clear that public transportation in Karbala is very weak and needs development, as the percentage of buses and minibusses did not exceed 30% of the total traffic volume

Selected Indicators of Al-Najaf Road Network: Public Transportation Noise and Pollution

It is urgently necessary to improve the state of transportation and related infrastructure, especially given that the most important indicators of urban development gauge a city's progress. One of the most influential of these indicators is what is known as "smart transport, " which refers to transportation that utilizes modern communication and information technology technologies to address various challenges in various transportation sectors. The holy city of Najaf smart transportation strategy seeks to reduce dangerous levels of traffic-related noise and air pollution while enhancing various aspects of mobility and traffic flow indicators. This study aims to evaluate the performance of the existing traffic network and public transport in Najaf City and its interference with noise and air pollution at selected points for data gathering by using field measurements using cameras, noise meters, and pollution measurement devices. The study states that the public transport sector in Al-Najaf city is significantly poor as private cars are dominant by about 65% of traffic mix with values of pollution and noise above the standards. One of the most effective solutions to traffic problems is the implementation of intelligent transportation systems. Part of these strategies is establishing a tram network and raising road classes’ strategies by proposing some geometric design editing, U-turns reducing, and raised ramps additions

Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

DESIGN AND STUDY OF A SMART PARK SYSTEM: UNIVERSITY OF KUFA AS A CASE STUDY

Finding a vacant parking space nowadays is time and fuel consuming. This problem may cause drivers to get frustrated and eventually improper parking will appear. The universities, in particular, are one of these places, which needs more attention for providing parking services. Therefore, this study has focused on finding the parking required for such facilities and the benefit of applying smart parking services there. The main campus of the University of Kufa has been evaluated by collecting parking data for both on-street and off-street parking. The results of field data show a clear lack of parking space for most of the faculties in the main campus. The required additional parking spaces are 260.This study has suggested using the smart parks. The model of smart park system has been introduced by this study as a solution to the parking problem, especially in the university and generally in other places. Arduino and ultrasonic sensors were used to detect the empty places in a park and display this status to the screen. The model has been applied at the park of College of Engineering with encouraging results
