TEMPO.CO, Jakarta - Transportation observer from Soegijapranata Catholic University Semarang, Djoko Setijowarno, opined motorcycle restriction was considerably more effective to be imposed rather than the expansion of the odd-even policy to curb air pollution and severe congestion in the capital.
“Motorcycle restriction that has been imposed on Jalan Merdeka Barat until Thamrin should have been expanded,” said Djoko, Monday, August 12.
Djoko said pollution in Jakarta and its vicinity was mostly caused by motorcycles as the majority vehicles, which accounted for 75 percent, followed by private cars with 23 percent and public transports with two percent.
Besides, the city's transportation agency recorded that the restriction policy in 2017 had reduced the vehicle volume up to 22.4 percent, increased vehicle speed to 30.8 kilometers per hour from the initial 26.3 km/hour, and boosted the traveling time by 15 minutes.
The Jakarta Police also concluded a drop in congestion sources, traffic violations, and traffic incidents at 30 percent. “This may sound like a political burden, but there is no harm to apply it for a broader impact,” Djoko remarked.
Djoko made his statement in response to the Jakarta Gubernatorial Instruction No. 66/2019 concerning air quality control, which stipulated the restriction of vehicle age and odd-even policy. The expanded odd-even policy is slated to take effect starting September 9, 2019.
