Distribution
In most cities, during rush hour, there is heavy traffic in one direction and light traffic in the other. If the lanes with the light traffic could be used for the rush hour traffic during rush hour times, traffic congestion may be alleviated to a certain extent.
How it would work
Get rid of fixed medians such as the one shown in the picture so that in-bound and out-bound lanes can be adjusted based on traffic density. Use a world harmonized color striped system on roads to indicate when and where that lane is in-bound and when and where that lane is outbound. Any other better system?

As far as I know, there are such streets in some places. The traffic is regulated by traffic lights and something else... perhaps.

Yes, there is an ad-hoc system in Mumbai as well. However, that requires manpower (police) presence and orange barrels. I was thinking more of a system that would function seamlessly without the need for temporary manpower or bandaged infrastructure.

Shireesh Apte Something like a railroad switch for lanes, which uses traffic cameras to decide which way to switch? One lane (the high-speed lane) on one side of the road (the outbound road) could be switched off for traffic. Once all the vehicles in that lane leave the next switch, the inbound lane could release vehicles through the switch into the empty lane. The vehicles are transferred back to the outbound lane once they approach the next switch. Multiple switches along a road could also help in case there are accidents and the road needs to be closed.

Madrid is an example - central bidirectional lane

I was fascinated by how Madrid dealt with this problem. The population of Madrid is a little above 3 million, while the Madrid Metropolitan area counts over 6 million! Many people living in the surrounding cities travel to work in Madrid. Since the rush hour is horrible in the morning towards the city, and in the afternoon in the direction heading outside, they created (using concrete walls) another central lane (between the two directions) which is:
  • in the morning open toward the city
  • in the afternoon open toward the Madrid surrounding cities
However, it can be used only by public and private transportation, including taxis, car sharing, etc. That means that you can use it if you are traveling with someone, and not alone.

Yes, other cities have dedicated lanes for public transportation like Bogota, Mexico city and Ahmedabad.. to name a few. However, I was thinking more along the lines of private cars and vehicles. Of interest: I have heard that in Indonesia (and probably other countries), people make a living by offering themselves as a rider so that the driver can then avail of the high occupancy lanes.

Shireesh Apte Maybe I didn't make it clear in the text above. You can use these separate lanes even if you are driving your private car. The only condition is that you are not alone in the car (that you share a car with someone - carsharing). The Indonesians would easily figure this one, too, then.

J. Nikola I think Shireesh Apte meant that in a system he has in mind, any vehicle could use the lanes, irrespectively from how many passengers are in/on it.

This could be easily used to adapt traffic to bicycles and electric scooters. Pop-up bike lanes could be formed on the existing lanes (where at least two go in the same direction) and used on sunny days for promoting green traffic and clean the cities from pollution.

J. Nikola yes indeed; the uses are multifarious.

J. Nikola They could also be used for marathons and cycle races without disrupting the traffic.
