Basically building new roads entices more people to drive that route, or not carpool, etc. Seems retarded but that's the concept.


Well, if by "retarded" you mean, "backed up with observation and research" then, you're correct. How many lanes do the highways around the beltway have? They could have 30 lanes each way and be a mile wide - still would have crushing traffic jams.

Efficiency of the traffic flow is far more important to eliminating congestion than adding lanes. Straighten out the lanes (as much as possible) - every curve and turn slows down traffic, even if you have 1000 lanes. And all the curves and turns stack and have a cumulative effect. Cut down on stops before turns/turning across traffic and such.

Adding lanes actually adds to your traffic volume. If the system is already efficient (straight with minimal interruptions) the added volume will be handled efficiently. If your system isn't efficient, adding lanes won't improve that efficiency 1 bit.

Efficient public transportation that people actually use would solve the problem also

By "retarded" I meant most people would think adding lanes would lighten the traffic.

There's only one true solution:
