Minister of Transportation, Budi Karya Sumadi, has revealed that traffic congestion in DKI Jakarta results in losses amounting to Rp100 trillion annually. Therefore, he encourages all parties to initiate the development of efficient mass transportation systems in every province. Budi Karya stated that having an efficient mass transportation system can reduce the losses caused by traffic congestion and also help in reducing air pollution.

"That's why I urge all stakeholders or other provinces to focus on improving mass transportation. This way, we can reduce the number of private vehicles, tackle traffic congestion, decrease air pollution, and reduce the economic losses of Rp100 trillion per year for Jakarta," said Budi Karya when met at the Jakarta International Velodrome on Monday, October 30, 2023. On the same day, the construction of LRT Jakarta Phase 1B Velodrome-Manggarai officially commenced. He appreciates the efforts of the Jakarta Provincial Government in promoting mass transportation in the region.

"I appreciate and encourage the community to switch to mass transportation because this way we can preserve the environment, address traffic congestion, and even eliminate financial losses," he said. The LRT Jakarta Phase 1B project will cover a distance of 6.4 kilometers and will have five new stations, namely Pemuda Station, BPKP Station, Pasar Pramuka Station, Matraman Station, and Manggarai Station.
