Vehicle Collision over time vs Instantaneous Traffic speeds.

This was just a small visualization I was experimenting with to show two contrasting data-sets on the same screen. The blue lines show the traffic speeds information (at the instant of 9/21/14 9:07pm) captured by various traffic speed detectors installed by the New York City DOT. In contrast, the red dots show the vehicle collisions that have happened in NYC over the last two years (2012-2014).
