Effects of the London Congestion Charge on Road Casualties: A Synthetic Control Study
Publication: CICTP 2019
Abstract
This paper aims to estimate the causal effects of the London congestion charge (LCC) on road casualties. In this paper, a synthetic control group is constructed to approximate the casualty number that the central London area would have experienced in the absence of the LCC. The results show that the total casualties within the charging zone is reduced by 4.29%, while the reductions in slightly and seriously injured are 5.05% and 12.12%, respectively. The results of placebo-controlled study show that the estimates of the effects of the LCC are all significant at the level of 95%. The significant reduction in casualty number is most likely due to the fact that the traffic volume has decreased since the introduction of the LCC, coupled with the fact that the total number of accidents decreases as the traffic volume decreases.
