Approximately one-quarter of all automobile collisions in the United States are thought to be caused by a distracted or inattentive driver. As more wireless communication, entertainment, and driver assistance technologies become available in vehicles, the number of distracted driving accidents is projected to rise. Driver distraction is a major concern in North America, Europe, and Japan when it comes to road safety. The importance of driver distraction as a road safety concern, on the other hand, has just lately been recognized. This study presents an overview of current studies on in-vehicle driver distraction, with an emphasis on mobile phone usage, as this technol-ogy has garnered the most attention in the literature on driver distraction. The impact of in-vehicle gadgets on driving performance is discussed in this review. The adaptive techniques driv-ers use to maintain acceptable driving performance when distracted are discussed, as well as the situations under which these adaptive tactics can fail and how driving performance is harmed when they do. Legislation prohibiting drivers from using their cellphones while driving has had minimal effect, presumably due to a lack of regulation and enforcement. As potential preventive measures to decrease accidents caused by distracted drivers, behavior modification programs, enhanced vehicle safety, and public awareness campaigns have been created.
The status of the infrastructure of the transport system and then mobility in the governorate of Anbar is deplorable. Therefore, it requires two types of solutions in two phases. This study concerned with the first phase, which is represented by solving the problem of the inadequacy infrastructure in terms of availability between the cities, and work to develop it toward being maximally connected. So, generally speaking this study aimed to facilitate mobility through this network, by improving the accessibility in term of connectivity. The analysis process in this study, have twin objectives: first, to determine how much new linkages we need for our network to be maximally connected as a first stage? Second, Building a legislative framework lends the weight for decision makers in transport agency to take tough decision built up on ranking the new proposed linkages according to their relative values in providing access to the network, and the increment in comparable nodal accessibility due to the new additions. So, there is need for more sensible decisions based on more accurate analysis for deciding the optimum priorities for the new linkages to take place in the stage of development implementation via legislative framework. Therefore, the analysis will deal with topological characteristics for a number of aspects by expressing the simple graph of the network in a matrix format. These aspects are simulated and measured through the matrices powering process and the principles of graph theory. However, in addition to reducing the time the vehicles stays on the road, the study results will assist to divert a large proportion of the traffic volumes concurrently with the implementation process, and this in turn will pave the way to precede the solution of the second phase inside the cities. Not to mention, the legislative framework will bases for the financial framework of the transport agency.
