Geometric roadway design can be broken into three main parts: alignment, profile, and cross-section. Combined, they provide a three-dimensional layout for a roadway. The alignment is the route of the road, defined as a series of horizontal tangents and curves.
A grid plan from 1799 of Pori, Finland, by Isaac Tillberg. The city of Adelaide, South Australia was laid out in a grid, surrounded by gardens and parks. In urban planning, the grid plan, grid street plan, or gridiron plan is a type of city plan in which streets run at right angles to each other, forming a grid. [1]
Site plans are often prepared by a design consultant who must be either a licensed engineer, architect, landscape architect or land surveyor". [3] Site plans include site analysis, building elements, and planning of various types including transportation and urban. An example of a site plan is the plan for Indianapolis [4] by Alexander Ralston ...
Plans would often show plan views (viewed from above), profile views (a "transparent" section view collapsing all section views of the road parallel to the chainage) or cross-section views (a "true" section view perpendicular to the chainage). In a plan view, chainage generally increases from left to right, or from the bottom to the top of the ...
The delay costs incurred by the conventional layout are 12% higher than the fused grid followed by the Neotraditional grid at 3% higher. The conventional layout is less cost-efficient than the fused grid network since they have similar infrastructure costs but the latter delivers significant savings in travel time costs.
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.

A common practice in conventional subdivision design is a road pattern that limits access to the arterials (or boulevards) to few points of entry and exit. These choke points produce traffic congestion in large subdivisions at rush hour periods. Congestion also increases on the boulevard (regional arterial) if the access restrictions are not ...
