Speed humps are a common physical measure installed at pedestrian crossings to reduce vehicle speeds therefore improve the safety and mobility of pedestrians at the crossing. The aim of this study was to determine whether variations in distance between speed humps and pedestrian crossings contribute differently to the safety and mobility of pedestrians and cyclists, especially children and the ...

In India major road accident is based on potholes. To identify this potholes and humps in roads may reduces the also damages cars bike. holes or speed breakers, ultra sonic sensor, display board buzzer used it. Project mainly prototype model of vehicle which has capable to find road. When hump it started showing distance obstacles, once obstacles reduced 10m range gives alarm signals drives tha...

-In this paper, an efficient numerical solution for the scattering problem of inhomogeueuns dielectric rough surfaces is presented. The inhomogeneous dielectric random surface represents a bare soil surface and is considered to be comprised of a large number of randomly positioned dielectric humps of different sizes, shapes, and dielectric constants above an impedance surface. Clods'with nonuni...
