The Jakarta Transportation Agency has revealed that the city will, again, try to implement the long-delayed electronic road pricing (ERP) system.

The agency’s acting head, Sigit Widjatmoko, said the city was in the process of finding partners to procure and build the ERP infrastructure.

“We aim to start implementing the ERP once the MRT starts operating [in March 2019],” Sigit told the press on Wednesday.

The ERP system, which will see vehicle owners charged for entering certain roads, is expected to solve traffic congestion in Jakarta, since 50 percent of vehicles moving on Jakarta’s roads are from outside the capital.

Greater Jakarta Transportation Body (BPTJ) head Bambang Prihartono said he hoped the ERP would be the next measure for the city [to tackle congestion] after the odd-even license plate policy.

According to Bambang, there will be three rings of the ERP in the city. The first ring will be Jl. Sudirman and Jl. MH Thamrin in Central Jakarta, and the second ring will be other main roads of Jakarta.

“The third ring are the national roads in the city’s border area,” Bambang said.

“We will also work with toll road operators. Just like with the ERP, toll roads will be more expensive when they are congested,” he added.
