Head of the DKI Jakarta Transportation Agency, Syafrin Liputo, said that his party had begun to prepare for the closure of 27 turning lines or U-turns in Jakarta.
Syafrin said the barrier installation that closed the route had begun to be carried out in stages. The 27 U-turn points were completely closed in June.
"The 27 U-turn points that will be closed are spread across 5 regions. We plan to complete the overall closure in semester 1, no later than June," said Syafrin at DKI Jakarta City Hall, Wednesday, February 8.
Syafrin said, the closure of 27 accesses to the back of this vehicle has passed a thorough study by means of simulations using transportation software.
Based on the study, U-turn is one of the causes of increasing traffic density. Because, there will be a slowdown in the rate of traffic when the vehicle turns around.
"U-turns are quite high in influencing movement. Because once the person concerned will rotate, usually the maneuver will take a lane and a half. This is what causes performance, the network (traffic) continues to decline," he explained.
In the first three months, 27 U-turn points will be closed using water barriers. At this time, the DKI Transportation Agency will evaluate the closure of the U-turn regarding the impact of breaking the congestion.
After evaluation, the means of closing the U-turn are permanently replaced using a movable concrete barrier (MCB) or concrete barrier. "We will automatically start the initial stage first. Automatically it will reduce people's efforts to make rounds there," he said.
