  2. Cross slope - Wikipedia

    en.wikipedia.org/wiki/Cross_slope

    Cross slope, cross fall or camber is a geometric feature of pavement surfaces: the transverse slope with respect to the horizon. It is a very important safety factor. Cross slope is provided to provide a drainage gradient so that water will run off the surface to a drainage system such as a street gutter or ditch.

  3. Drainage gradient - Wikipedia

    en.wikipedia.org/wiki/Drainage_gradient

    Typically on straight road sections, the drainage gradient is at least 1–3% due to the normal cross slope of 1–3%. In curved sections the drainage gradient is higher, and may often reach 5–12% due to superelevated CS that may reach 5–8% in areas with icy roads and up to 12% in areas without icy roads.

  4. Geometric design of roads - Wikipedia

    en.wikipedia.org/wiki/Geometric_design_of_roads

    The cross section of a roadway can be considered a representation of what one would see if an excavator dug a trench across a roadway, showing the number of lanes, their widths and cross slopes, as well as the presence or absence of shoulders, curbs, sidewalks, drains, ditches, and other roadway features.

  6. Curb cut - Wikipedia

    en.wikipedia.org/wiki/Curb_cut

    A pram ramp with tactile paving that connects a sidewalk to a road. A curb cut , curb ramp, depressed curb, dropped kerb , pram ramp, or kerb ramp is a solid (usually concrete) ramp graded down from the top surface of a sidewalk to the surface of an adjoining street. It is designed primarily for pedestrian usage and commonly found in urban ...

  7. Road surface - Wikipedia

    en.wikipedia.org/wiki/Road_surface

    In landscape architecture, pavements are part of the hardscape and are used on sidewalks, road surfaces, patios, courtyards, etc. The term pavement comes from Latin pavimentum, meaning a floor beaten or rammed down, through Old French pavement. [5] The meaning of a beaten-down floor was obsolete before the word entered English. [6]

  8. Diverging diamond interchange - Wikipedia

    en.wikipedia.org/wiki/Diverging_diamond_interchange

    Pedestrian (and other sidewalk-user) access requires at least four crosswalks (two to cross the two signalized lane crossover intersections, while two more cross the local road at each end of the interchange). [42] [41] This could be mitigated by signalizing all movements without impacting the two-phase nature of the interchange’s signals.

  9. Interstate Highway standards - Wikipedia

    en.wikipedia.org/wiki/Interstate_Highway_standards

    Pavement sloping: On straight sections of the highway, the roadway is to have a cross slope of at least 1.5%, and preferably 2% to ensure proper drainage, with up to 2.5% in areas of heavy rainfall. The cross slope of both the left and right shoulders should be between 2% and 6%, but not less than the main lanes.
