vägnätsgeometri

Vägnätsgeometri refers to the study and design of the spatial arrangement and physical characteristics of road networks. It encompasses various elements that define how roads are laid out and interact with each other, influencing traffic flow, safety, and efficiency. Key aspects include road alignment, which describes the horizontal and vertical curves of a road, and the intersection design, where roads meet. Intersection types can range from simple cross-sections to complex interchanges, each with its own geometric considerations for managing traffic.

The geometry of a road network also considers elements like sight distance, which is the length of roadway visible to a driver, and lane geometry, including width, superelevation (the banking of curves), and shoulder design. The overall structure of the network, whether it's a grid, radial, or organic pattern, is also part of its geometry. Understanding and optimizing vägnätsgeometri is crucial for transportation engineers to ensure that roads are safe, functional, and can accommodate current and future traffic demands. It involves balancing capacity needs with environmental constraints and the surrounding landscape.
