Jakarta. According to the Ministry of Transportation, overloaded trucks are the main cause of traffic jams on the Jakarta-Bandung Toll Road.
While the time to reach West Java's capital from Jakarta through the 140-kilometer toll road should be three hours, it now takes between five and six hours, on average.
The ministry decided to investigate the causes of congestion.
"We inspected the toll road and will try to identify the causes," Transportation Minister Budi Karya Sumadi said, while visiting one of the toll road's gates in Cikarang Utama on Sunday (21/01).
One of the obvious causes is that 76 percent of the trucks passing the road are overloaded, which makes them move slowly.
As trucks and buses were involved in 63 percent of accidents and crashes on the road, the minister ordered the Directorate General of Land Transportation and the police to conduct more frequent inspections from Monday.
"We hope that in three weeks travel time will return to its normal," he said.
Budi also plans to limit the flow of trucks to one lane.
"We will also set time limits on when they can enter [the road]. This rule is common in other countries," he said.
State-owned toll road operator Jasa Marga records more than 100,000 trucks on the toll road each day. They account for 20 percent of vehicles on the route.
