Road Geometrics part 1,Highway engineering, civil engineering
Road Geometrics Introduction "Road geometrics" means fixing up of visible dimension of a road so that the traffic could utilize it conveniently for its safe and comfortable movements. The geometric design of highways provide these facilities. Road Geometrics include the following features: Cross-section elements such as formation width, carriage way, camber, gradient etc. Sight distance considerations such as stopping and passing sight distance. Horizontal and vertical alignment including transition curves and super elevation. Although the road geometrics are greatly influenced by topography of land, locality or area and traffic requirements, but design speed is the most important controlling factor in the geomteric design of highways. Glossary of important terms used in road geometrics Road Geometrics: the proper planning , design and fixing up of visible dimensions of highway for providing optimum speed, comfort and maximum safety to road users at a minimum operational cos...
