Sometimes the result of roadwork may leave visible marks on the pavements. An example is the dowel bar retrofit process to reinforce concrete slabs in order to extend the life of older concrete pavements. The completion of the process leaves a symmetrical pattern of dash marks on the roadway, as if there were an associated meaning to the ...
Hatch marks (also called hash marks or tick marks) are a form of mathematical notation. They are used in three ways as: Unit and value marks — as on a ruler or number line; Congruence notation in geometry — as on a geometric figure; Graphed points — as on a graph; Hatch marks are frequently used as an abbreviation of some common units of ...
Tally marks, also called hash marks, are a form of numeral used for counting. They can be thought of as a unary numeral system . They are most useful in counting or tallying ongoing results, such as the score in a game or sport, as no intermediate results need to be erased or discarded.
In sports, a hash mark or hash line is a short line/bar marking that is painted perpendicular to the sidelines or side barricades, used to help referees and players recognize on-field locations and visually measure distances. Hash marks serve the same function as the graduated markings on measuring tools such as rulers.
Hatch marks may or may not be labeled. If not labeled, the pattern of the marks tells the viewer the value of the number line at the location marked by a specific hatch. For example: Comment: This is true for only the usage of hatch marks as unit markers. The example shows a number line, but it does not show a hatch pattern.
For bypasses, connecting roads, and parallel roads, the shield combines the "G" designation with a two-digit main line number, a type identifier, and a sequence number. Provincial expressways start with the letter "S". The main arteries and city bypass/connecting road shields display the "S" followed by up to two or two digits, respectively.
A common example is a sharp curve at the end of a long tangent section of road. The concept of design consistency addresses this by comparing adjacent road segments and identifying sites with changes the driver might find sudden or unexpected.
In addition to marking the road edge, delineators are used to mark ramp gores, medians, and objects near the roadway such as fire hydrants. In such areas, the height of the delineators is established based on the typical amount of snowfall the area receives, ranging from 4 feet to more than 8 feet in height in areas with extreme snow depths.
