Jersey barriers on the road. A Jersey barrier, Jersey wall, or Jersey bump is a modular concrete or plastic barrier employed to separate lanes of traffic.It is designed to minimize vehicle damage in cases of incidental contact while still preventing vehicle crossovers resulting in a likely head-on collision.
The F-shape barrier is a concrete crash barrier, originally designed to divide lanes of traffic on a highway. It is a modification of the widely used Jersey barrier design, and is generally considered safer. [1] A parametric study, one that systematically varies the parameters, was done through computer simulations of barrier profiles labeled A ...
A geometric design saved on construction costs and improved visibility with the intention to reduce the likelihood of traffic incidents. The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in ...
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.
Typical left-hand motorway road layout in Ireland and South Africa Divided median strip on a boulevard in Huizhou, China. A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways.

The elevated illustration, [8] reminiscent of the Miller Highway and some of its descendants, featured partial left lane ramps, a highway running across the width a populated boulevard, almost building-to-building, a local traffic lanes underneath the highway. The report also includes a picture of the then-recently constructed Gowanus Parkway ...
Also, the West Road interchange on I-75 in Woodhaven, Michigan, was upgraded from a B2 to a B4 in the mid 1980s after suburban sprawl had made the B2 interchange obsolete. In Indiana, the B4 design along IN 37 at its Bloomington interchange with IN 45/46 was retained when the former route was converted to become I-69's exit 120 in 2018.
