From Wikipedia, the free encyclopedia.
Highway engineering is the process of design and construction of efficient and safe highways and roads. It became prominent recently and has its roots in the discipline of civil engineering. Highway engineering standards are continuously being improved. Concepts such as grade, surface texture, sight distance and radii of horizontal bends and vertical slopes in relation to design speed, in addition to interchange design and important sign boards, are all important elements of highway engineering. Most developed nations have extensive highway networks based on the traffic density.
Geometric design Edit
The modern geometric design of roads is based upon safety concerns for the vehicles' passengers. To put this goal into practice, concepts such as grade, surface texture, sight distance and radii of horizontal bends and vertical slopes, were developed.
