Study Notes

Surveying and Sampling

Avoid bias by ensuring every population individual is invited to respond.
Representative sampling requires careful selection of individuals across important characteristics.
The most reliable sampling method gives every combination of individuals an equal chance of selection.

Road Safety Markings

Thermoplastic lane markings offer visual, audio, and motion warnings for motorists.
Rumble strips indicate increased vehicle safety but lane lines should not extend across:
- Signalized intersections.
- Side street entrances unless one-way.
- Past the taper at multi-lane road narrows.
Lane lines of low priority roads must cease at intersections.

Pavement Markings and Messages

Messages on pavement should be limited to six words or less.
Types of pavement and curb markings include:
- Longitudinal lines, transverse lines, lane lines, and center lines.
Shoulder paving enhances pavement integrity, provides width for markings, and adds safety to prevent skidding.

Road Design Considerations

Design of overtaking and climbing lanes must account for diverge taper, auxiliary lane length, and merge taper.
Safety barriers are warranted based on slope steepness, unforgiving hazards, and water hazards in the clear zone.

Nautical Terms

A body of water that remains navigable to a harbour is known as a 'fairway'.
Structures built into water but not parallel to the coastline include jetties, piers, and wharfs.

Azimuth Calculation and Design

To determine south with a watch, align the hour hand with the sun's position and find the midpoint.
Minimum sag vertical K value considers sight distance, low filling requirements, and riding comfort.
Step-by-step azimuth calculation involves planning, performing, checking calculations, and calculating both clockwise and counter-clockwise.

Vehicle Capacity

Capacity reflects the maximum number of vehicles or passengers a facility can accommodate under service limitations.
Capacity is a primary safety consideration in geometric highway, runway, and taxiway design.

Control Types in Jobsite Management

Primary, secondary, and working control categorize jobsite management.

Vehicle Measurement Basics

Density measures vehicles per unit distance on roadways, often expressed in vehicles per mile or kilometer.
Flow indicates the number of vehicles that pass a particular point over time.
