👉 Traffic fluid refers to the continuous flow of vehicles and pedestrians on a road network, governed by principles similar to fluid dynamics. It encompasses the movement of vehicles as a cohesive unit, influenced by factors such as speed, density (number of vehicles per unit length), and flow rate (vehicles passing a point per unit time). Traffic fluid theory helps model and predict traffic behavior, optimizing road design and management to minimize congestion and improve safety. It considers both free-flow conditions, where vehicles move smoothly without significant interactions, and congested conditions, where delays and stop-and-go patterns prevail, providing insights into traffic control strategies like signal timing and lane management.
