A recent traffic study revealed that altering the geometry of an intersection can reduce total pollutant emissions by over 50%! This is a fantastic finding which we hope will entice more traffic engineers and municipalities to closely evaluate the appropriate designs of their intersections. This is important as this can have a significant impact on the local air pollution and in turn the health of people living there especially if implemented on a larger scale. So, traffic
intersection design truly matters, and not just because of the safety or optimal traffic throughput.
