The "3 in 1 rule" in Jakarta was a traffic regulation that mandated a minimum occupancy of three passengers, including the driver, for private vehicles traveling on certain major roads during specific hours.
Understanding Jakarta's Former 3 in 1 Policy
The 3 in 1 rule was implemented in Jakarta as a measure to mitigate severe traffic congestion. Under this policy, private cars were required to carry at least three occupants to be permitted entry onto designated routes, primarily main thoroughfares in the city center, during peak hours. The primary objective was to encourage carpooling, thereby reducing the number of vehicles on the road and easing traffic flow.
How the 3 in 1 Rule Operated
- Minimum Occupancy: Vehicles needed to have a minimum of 3 passengers, including the driver.
- Designated Areas: The rule applied to specific main roads within Jakarta.
- Time Restrictions: It was enforced during certain busy hours of the day.
This policy aimed to shift commuters from single-occupancy vehicles to shared rides, which theoretically would decrease the overall volume of traffic.
Replacement by the Odd-Even Rule
The 3 in 1 policy is no longer in effect in Jakarta. It has been replaced by the odd-even traffic rule. The odd-even rule allows vehicles to use specific roads only on certain days based on whether their license plate number ends in an odd or an even digit, alternating daily. This current system serves the same overarching goal of managing traffic congestion in the Indonesian capital.
Evolution of Traffic Management
Jakarta's move from the 3 in 1 rule to the odd-even rule reflects an ongoing effort to find effective solutions for its persistent traffic challenges. While the 3 in 1 rule attempted to reduce the number of cars by increasing occupancy, the odd-even rule restricts vehicle movement based on plate numbers, aiming to distribute traffic flow more evenly throughout the week.
