    Abstract: This paper deals with the effectiveness of various bracing systems used in lattice towers. Seven types of bracings used in 4-legged square based self-supporting power transmission and telecommunication towers and four types of bracings used in 3-leg triangular based self-supporting telecommunication towers are analyzed. The investigated bracing sys... Show More

    Abstract: Safe roads are the foundation for the traffic safety. An accident is an unintentional injury, incidental and unplanned event that are caused by the transfer of energy between the human body and the environment. It involves a minimum of one road vehicle during which at least a minimum of one person is dislocated or killed. They impose a huge socio-e... Show More

    Abstract: In the estimation of saturation flow at signalized intersections using the HCM model, the influence of area-type characteristics on flow is accounted for by the area-type adjustment factor (fa). The recommendation by the manual to use fa=0.9 for CBD-intersections and 1.0 for all others tacitly assumes that the nature of non-CBD areas does not influ... Show More
