Pavement Design- Highway Engineering (Chapter-4)
Pavement is a load-bearing & load-distributing component of a road. We need to consider all types of vehicles for the geometrical design, but only vehicles with significant heavy loads are considered for pavement design. These vehicles are generally commercial vehicles. As per IRC, vehicles having a gross load greater than 3 tons are called commercial vehicles.
Gradually Varied Flow- Open Channel Flow (Chapter-4)
The gradually varied flow (GVF) is defined as steady non- uniform flow, where the depth of flow varies gradually from section to section along the length of channel. (A steady non-uniform flow in a prismatic channel with gradual changes in its water surface elevation is termed as gradually varied flow (GVF).
Traffic Engineering- Traffic Studies and Analysis- Traffic Volume Study & Traffic Speed Studies
Traffic studies or surveys are carried out to analyze the traffic characteristics. These studies help in deciding the geometric design feature and traffic control for safe and efficient traffic movements. The traffic surveys for collecting traffic data are also called traffic census. The various traffic studies generally carried out are: Traffic Volume Study, Traffic Speed Studies.
Photogrammetry (Types of Photogrammetry, Types of Photographs, Scale of Photograph, Relief Displacement, ETC)
In this photogrammetry chapter, we detailed discuss about photogrammetry, aerial photogrammetry, vertical photograph, scale of photograph, datum scale of photograph, average scale of photograph, flying height, ground co-ordinates & length of a line from a vertical photograph, crab, drift, relief displacement, number of photograph required to cover an area, exposure interval, air base, etc.
