Road traffic is a multi-billion dollar drain on the US economy. Using machine learning, trend analysis, and Bayesian statistics, we explored patterns and causes of traffic at the intersection of Culver Road and East Main Street in Rochester, NY. This analysis was presented at the 2015 UP-Stat competition in Geneseo, NY.
