More than 2,000 vehicles have been booked for violating the odd-even traffic system since it was implemented in the city two weeks ago.

The system requires alternating turns for cars entering the city’s main roads according to the number on their licence plates - odd-numbered licence plates will access roads on odd-numbered dates and even-numbered plates on even-numbered dates.

It was introduced after the city administration phased out the controversial ‘three-in-one’ carpooling system.

Metro Jaya traffic police chief Budiyanto was quoted by online media as saying that stern action had to be taken to ensure compliance by motorists.

He said based on observation, the system had been able to ease traffic congestion, as well as traffic flow, in the city.

The number of drivers booked for violating the system was also lesser, he said, adding that the errant drivers faced a maximum fine of Rp500,000 (about RM150).

Jakarta is among the top 10 cities with the world’s worst traffic with more than 20 million vehicles on the road every day.
