The Impact of Large-Scale Social Restriction and Odd-Even Policies During COVID-19 Pandemic to Traffic Congestion and Air Pollution in Jakarta

The COVID-19 pandemic has had a global impact on transportation mobility and air pollution, including Jakarta as the capital and busiest city in Indonesia. This paper reports the impact of two policies imposed by the Governor of Jakarta, namely the odd-even and the large-scale social restriction (PSBB) transitional phase-1, against the traffic congestion and air pollution quality in Jakarta during the COVID-19 pandemic. This paper investigates the odd-even and PSBB policy impact using paired T-Test. Moreover, this study assesses the relationship between traffic congestion and air pollution using the Pearson correlation. The result shows that the odd-even policy does affect significant only on MH Thamrin Street. Furthermore, the odd-even policy does not significantly affect air pollution reduction in Jakarta. This study also found that there is no meaningful relationship between traffic congestion and air pollution. These results can be used to reference future data-driven policy improvement on traffic congestion and air pollution management in Jakarta and other cities.
