Transportation is an indispensable factor on the successful hosting of the Olympic games. Comprehensive traffic management measures are essential to alleviate the traffic congestion during the Olympic games. In this paper, we studied the effects of the Traffic System Management (TSM) of the Tokyo 2020 Olympic games on the Tokyo Metropolitan Expressways (MEX). We further proposed a methodology to estimate the effects of TSM and Traffic Demand Management (TDM) separately based on the empirical data, and applied the methodology on a specific route as a case study. The results for the case study suggested that TSM was efficient for reducing onramp traffic demands, which will further contribute to the total delay reductions at merging bottlenecks. We found that on several days TSM was excessively implemented, and TSM worked more efficiently during the latter part of Olympic games.
