Understanding the dynamics of vehicular traffic is important to planning and improving shared public roadways, not only to effectively and efficiently facilitate the controlled movement of vehicles, but also to guarantee the safety of individuals in the vehicles. Because data from real-world traffic is difficult to measure, and conducting replicated experiments on humans has ethical and economi...

In this paper, two formulas were chosen among those that estimate the suspendedsediment discharge in rivers. These two formulas were Lane and Kalinske and Bagnold. Forstudying and knowing the correlation between input parameters and calculated suspendedsediment discharge (CSSD), the SPSS17 software was used. Input parameters in these twoformulas were as: water velocity, water discharge, suspend...

The Kansas Department of Transportation (KDOT) became interested in roundabouts in 1998 and started designing and building roundabouts on state highways in Kansas (KS). They sponsored three research projects to get before and after data at several Kansas roundabout locations. These studies are still on going at Kansas State University (KSU). Concurrently, the traffic engineer in the City of Man...

give access to the through pavements only at limited intervals. Where pavements pass through highly developed areas, I think such service drives will be necessary to overcome constant interference of traffic turning in and out of the property with through traffic. These service drives would not, of course, be improved to nearly as high type as the through pavements. In most cases a surfacing of...

The results of an extensive literature review of the safety performances of lowand intermediate-traffic-volume, two-lane rural highways are presented. The effects on traffic safety, as measured by accident rates, of pavement width, radius of curve/degree of curve, gradient, sight distance, traffic volume, and design speed on curved sections of two-lane rural highways are covered. The following ...

In this paper, a Laser simulator search graph approach for free-path search graph in complex unstructured environments has been developed and implemented for a robust mobile robot navigation system through the roundabout environments settings. The principle and methodology of laser simulator approach was clearly presented and explained for visibility searching of the optimum path in unknown env...

present study is an extension of earlier work carried out on two-lane two way roads in the two provinces of pakistan i.e. n-25, n-55 and n-5 regarding the measure of operating speed and development of operating speed prediction models. curved sections of two-lane rural highways are the main location of run-off road accidents. in addition to that the road alignment having combination of geometri...
