City Transportation Agency chief Udar Pristono said that the administration would coordinate with the police to enforce the policy.
"The even-odd restriction would serve as a transition from the 3-in-1 policy and the Electronic Road Pricing [ERP]," he
said the agency had calculated that the restriction would increase the average speed on Jakarta's roads from 16.8 kilometers per hour to 47 kilometers per hour and cut down roads affected by jams from 43.7 percent to 32.7 percent.
The restriction is also expected to save up to Rp 8.85 trillion (US$920 million) worth of productive time and vehicle operational cost as well as 345,000 liters of subsidized fuel each year.
The agency has also calculated that cutting almost half of the vehicles used each day would result in a need to provide an alternative for around 2.6 million person trips each day.
said that the city would compensate by providing a total of around 500 new buses in the BRT, granting 1,000 new minibuses to replace decade-old public minibuses (Metromini and Kopaja), and integrating the minibus services to the BRT system.
