Lighthill-Whitham-Richards model
The Lighthill-Whitham-Richards (LWR) model is a mathematical framework used to describe traffic flow on roads. It treats traffic as a fluid, where the density of cars (how many are on the road) and their speed change over time. The model uses this concept to predict how traffic moves and reacts to congestion, helping understand and manage traffic patterns. It can be applied to improve road design, signal timing, and traffic management strategies to reduce congestion and enhance travel efficiency. Essentially, it helps simulate and analyze how vehicles behave in a given roadway environment.

The Lighthill-Whitham-Richards (LWR) model is a mathematical framework used to describe how traffic flows on roads. It simulates how vehicles move based on their density (the number of cars per unit length) and speed, providing insights into traffic patterns and congestion. The model operates on the principle that the flow of traffic can be predicted by changes in density, helping engineers and planners design better road systems and manage traffic more efficiently. By analyzing these dynamics, the LWR model aids in understanding and mitigating issues like traffic jams and safety on highways and city streets.
