The street hierarchy is an urban planning technique for laying out road networks that exclude automobile through-traffic from developed areas. It is conceived as a hierarchy of roads that embeds the link importance of each road type in the network topology (the connectivity of the nodes to each other).

The expansion caps belong at each end of the dowel bar and the dowel bar support chairs are used to firmly hold the dowels centered in the slots during backfill operations. The foam core insert is used to re-establish the joint or crack, which allows the bar within each side of the slot to expand and contract.
The alignment is the route of the road, defined as a series of horizontal tangents and curves. The profile is the vertical aspect of the road, including crest and sag curves, and the straight grade lines connecting them. The cross section shows the position and number of vehicle and bicycle lanes and sidewalks, along with their cross slope or ...
According to Charles Marohn, a stroad is a bad combination of two types of vehicular pathways: it is part street—which he describes as a "complex environment where life in the city happens", with pedestrians, cars, buildings close to the sidewalk for easy accessibility, with many (property) entrances / exits to and from the street, and with spaces for temporary parking and delivery vehicles ...
