Greenshields model
The Greenshields model is a mathematical approach used to describe how vehicle speed on a road changes with traffic density. Essentially, it suggests that as more cars fill a roadway, the average speed of those vehicles decreases. This relationship is typically depicted as a linear equation, indicating that speed drops steadily as congestion increases. The model helps traffic engineers understand and predict traffic flow, enabling them to improve road design and traffic management strategies to reduce congestion and enhance safety on roadways.

The Greenshields Model is a theoretical framework used in traffic flow analysis. It describes the relationship between vehicle speed and traffic density, suggesting that as more vehicles occupy a road, their speed decreases. The model sees traffic flow as a balance where low density means high speeds, while high density results in slower speeds and potential congestion. Essentially, it helps traffic engineers understand how traffic behaves under different conditions, assisting in designing better road systems and managing congestion effectively. By examining this relationship, planners can implement strategies to improve traffic efficiency and safety.
