Roundabout Studies in Kansas
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...
متن کاملBenefits of a roundabout
Electronic and nuclear spins in insulating crystals interact weakly with their environments, making them candidate systems for applications in quantum information processing [1, 2]. Several features of the nitrogen vacancy (NV−) center in diamond (see Fig. 1) make it ideal for this purpose, as well as for sensitive magnetometry [3, 4]: The electron spin has been shown [5] to store quantum infor...
متن کاملTurbo-roundabout use and design
The turbo-roundabout concept has recently emerged in the Netherlands as a viable alternative to conventional multilane roundabouts, aiming to solve a set of functional problems related to the weaving maneuvers in the entry and negotiation zones. Although this is a recent concept, the Dutch experience has been showing that it is an extremely efficient solution, mainly in terms of safety. In fact...
متن کاملModels of Roundabout Lane Capacity
1 Accurate roundabout capacity models are essential for optimal roundabout 2 designs, but there exists significant differences in the predicted capacities of various 3 state-of-the-art models and in their included explanatory variables. An empirical 4 study into roundabout lane entry capacity was thus performed in the U.K. using data 5 from 35 roundabout entry lanes, where various model forms a...
متن کاملMulti-lane Roundabout Capacity Evaluation
Although two-lane roundabouts theoretically exhibit excellent operating performance, in practice, safety problems arise because of inappropriate driving behavior. Turbo roundabouts, which are characterized by a much higher level of safety, are alternatives to classic two-lane roundabouts, but the capacity-related benefits derived from such roundabouts remain an open issue. Accordingly, this stu...
