Everyone has experienced stop-and-go waves on freeways, and most traffic scientists and engineers know that traffic waves can propagate in the opposite direction of traffic flow at a relatively constant speed. But have you ever seen a wave split into multiple waves and merge back together? Here, you can explore the beauty of wave dynamics!
You can select the lane number (defualt lane 1, i.e. HOV lane) and then click on the "Load Lane Data" button to view the clusters of wave components by the number of bifurcations, the number of mergers, and wave length. Go ahead, click on any point to discover the detailed wave component!
The visualization panel is a simplified scatter plot of the wave length (mile, in Y-axis) vs. the number of bifurcations (in X-axis). Click here to view the visualization panel if it is not visible on your screen.
You can have an idea of how complex each wave component is (based on the number of bifurcations) and how long it is (wave length).
Highlight: Wave topology can range from remarkably simple to incredibly complex. Some waves travel over three miles without any bifurcations before merging, while others can bifurcate more than 10 times along their propagation!
Click on any point on the "Cluster Visualization" plot to view the corresponding detailed wave component in the SVG format.
Enjoy the beauty of the wave dynamics!

To explore wave components by date, first select a date, then choose a cluster of interest. Click "Next" to view detailed wave components by clicking the buttons under "Available Indices". This will display all wave components for the selected date, lane, and cluster, along with information on wave length, number of bifurcations, and number of mergers.
