One of the most important decisions in urban planning is understanding how to manage the flow of traffic. To assist with this, researchers have developed a way of visualizing traffic cell movements on a 3D map. By utilizing a method called particle tracking velocimetry, they are able to measure the speed and direction of traffic flows over time. This gives urban planners a better understanding of the dynamics of traffic flows, allowing them to plan more efficient road networks and better manage traffic. The researchers are also able to detect traffic jams and suggest appropriate solutions. This new method of visualizing traffic cell movements is a huge step forward in the planning of our cities.
