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.
Unsteady Flow: Surge- Open Channel Flow (Chapter-6)
Rapidly Varied Flow: Hydraulic Jump- Open Channel Flow (Chapter-5)
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 Control Devices & Regulation – Traffic Sign & Road Marking
Traffic Control Devices & Regulation – Traffic Signal
Traffic Control Devices & Regulation – Intersection
Traffic Studies and Analysis- Origin and Destination Study, Accident Study, Parking Study
Traffic Studies and Analysis → Traffic Flow Characteristics & Capacity Study
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.
Traffic Engineering – Traffic Characteristics
Vertical Curve (Summit Curve, Length Of Summit Curve, Valley Curve, Length Of Valley Curve)
Theodolite Survey (Classification of Theodolite, Components of a Vernier Theodolite, Temporary & Permanent Adjustment)
Special Instrument (Hand Leveling, Abney Level, Indian Pattern Clinometer, ETC )
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.
