Study Notes
Surveying
- Bias in Surveying: Key to avoiding bias is using a sampling method where every combination of individuals has an equal chance of being selected. This ensures that the sample accurately reflects the population.
Road Safety
- Safety Barriers Use: Use safety barriers if hazards like steep slopes, unforgiving obstacles, or water hazards are present within the road's clear zone.
- Pavement Messages: Pavement messages should be concise, limited to four words or less for optimal readability and driver comprehension.
Road Markings
- Pavement Markings: Four main types of pavement markings: Longitudinal lines, transverse lines, stop lines, and center lines.
- Overtaking and Climbing Lanes: Design considerations include the initial diverge taper, auxiliary lane length, and end or merge taper.
Traffic Flow
- Traffic Density: Traffic density is measured by the number of vehicles present on a road segment at a given moment, typically expressed as vehicles per mile or per kilometer.
Maritime Infrastructure
- Wharf: A continuous structure alongside a waterway allowing ships to dock for loading, unloading, or resting.
- Pier: A structure extending into the sea from the shore, used for similar purposes as a wharf.
- Port: A body of water with navigable depth providing access to a harbor.
- Channel: A navigable waterway leading to a harbor.
Road Design
- Vertical Curves: These curves are typically parabolic, connecting vertical tangents.
- Shoulder Paving: It provides structural integrity to the pavement, width for edge line markings, safety by preventing vehicles from skidding, and lower maintenance costs compared to unpaved shoulders.
Navigation & Time
- Determining South with a Clock: Align the hour hand of a watch with the sun, and south will be located halfway between the hour hand and the number 12.
- Site Plans: North direction, legends and symbols, scale, and a vicinity map are crucial components of a site plan, aiding orientation and understanding.
Road Geometry
- Azimuths: Azimuths are calculated clockwise. Steps involve planning, performing the calculation, checking the calculation, and calculating azimuths for both clockwise and counterclockwise traverses.
- Geometric Relationships: There are specific relationships applicable to instruments used in surveying, such as the perpendicularity of the vertical axis to the plate level axis, and the perpendicularity of the line of sight to the horizontal axis.
- Stopping Sight Distance: Stopping sight distance comprises two components: reaction distance and braking distance.
Highway Design
- Geometric Cross-section: Drainage, shoulders, and railways are fundamental elements considered in the design of highway cross-sections, runways, and taxiways.
Traffic Engineering
- Capacity: The maximum number of vehicles, passengers, or pedestrians that a facility can handle at a given service level.
Construction Management
- Work Control: There are typically three levels of control in construction: primary, secondary, and working control.
