There has been an interesting experiment going on in Jakarta this week. The city administration has suspended temporarily the 3-in-1 rule whereby at peak traffic times cars, on some of the more critical roads of the city, have to carry a minimum of three passengers (including the driver). This rule has resulted so called Jockeys, people who are passengers for hire, waiting on the side of the streets to be picked up as the third person. The 3-in-1 rule has only marginally reduced the traffic congestion. Relaxing the rule has therefore resulted (on average) in a marginal increase in the traffic congestions, although, speaking to friends, it seems that traffic on main arteries has worsened considerably, while smaller alternative roads seem to be more free of traffic.
In the meantime, it would be great if there were more bicycles in the streets, more commuters cycling to work, more bicycle lanes protecting cyclists, more parking space for bicycles. That would really make a difference.
