In collision analysis, what does 'intersection' define?

In collision analysis, the term 'intersection' primarily defines the area embraced by the prolongation of the lateral curb lines. This definition encompasses the entire space where two or more roadways meet or cross. It includes not only the physical point of convergence but also the surrounding area that is impacted by the merging of different traffic flows, making it crucial for analyzing accident patterns and factors at these locations.

This comprehensive understanding is essential for traffic engineers and safety analysts as they evaluate how vehicles, pedestrians, and other elements interact at these critical points. The area defined by curb lines accounts for the complexity of traffic movement, which is a significant consideration when studying collisions in those zones.
