Japek II South and Bocimi Prepared as Valves for Return Flow, Main Toll Burden Divided
REPUBLIKA.CO.ID, CIKAMPEK — The National Traffic Police Corps is counting on the Jakarta-Cikampek II South Toll Road and Bocimi to split the density of the 2026 Lebaran return flow. These two routes are being prepared as alternatives to reduce the vehicle load heading towards Jakarta.
Vehicle distribution indicates that 30 to 35 percent of the flow comes from West Java. This situation is driving the strengthening of alternative routes to prevent density from concentrating on the main toll section.
National Traffic Police Corps Chief Inspector General of Police Agus Suryonugroho stated that Japek II South has been trialled and is ready to be operationalised during the peak return flow. “From West Java, the solution is quite strategic because we have trialled Japek II South,” said Agus at the National Traffic Police Corps Command Centre in Cikampek on Sunday (22/3/2026).
The Japek II South section will be opened from Sadang to Setu to increase road capacity. This route is expected to handle the surge of vehicles from southern West Java.
Bocimi is also being prepared to support vehicle flow distribution. The integration of these two sections is hoped to reduce build-ups on the main route.
“From West Java, there is already Japek II South, which is very helpful, including Bocimi,” Agus remarked.
The Traffic Corps will continue to combine this scheme with other engineering measures such as one-way and contraflow. Arrangements will be made based on field monitoring of vehicle volumes.
The return flow from Trans Java is estimated to reach around 66 percent. This flow has the potential to meet vehicles from West Java at several congestion-prone points.
“From Trans Java, it’s approximately 66 percent. This is what we must manage,” said Agus.
The Traffic Corps is also anticipating a surge in mobility post-Lebaran. Inter-regional movements such as in Jabodetabek, Greater Solo, Greater Semarang, and up to Bali are predicted to increase traffic pressure.
Security will be carried out through security posts, service posts, and integrated posts. Supervision will also focus on tourist areas and ports to prevent congestion.
The Traffic Corps ensures that all strategies are implemented flexibly according to field conditions. Return flow control is carried out in an integrated manner to maintain smooth travel.
