Professional Sporting Events and Traffic: Evidence from US Cities

Abstract

Sporting events concentrate people at specific locations on game day. No empirical evidence currently exists linking sporting events to local traffic conditions. We analyze urban mobility data from 25 US metropolitan areas with MLB teams over the period 1990 to 2014 to assess the relationship between local traffic and Major League Baseball (MLB) games. Instrumental variable regression results indicate MLB attendance causes increases in local vehicle-miles traveled. At the sample average attendance of 2.8 million, average daily vehicle-miles traveled increases by about 6.9% in cities with MLB teams. Traffic congestion increases by 2%, suggesting that MLB games generate congestion externalities.
