Another situation caused by MONEY.
If traffic volume increases over time, the typical solution is to build another highway, or add lanes to the existing one. In built-up areas of high property values and/or historical districts, either of those two choices is impossible.
By studying the traffic flow volumes over time, engineers can see if peak volumes can be channeled over existing streets and roads. Thus, a solution of making a two-way street temporarily one-way during “rush hour” is workable. Not perfect, but workable. The direction will usually change during the opposite rush hour period.
There are overhead signs that are above each lane, in each direction, with signalization indicating if a street lane is one way or two way.
This means, for instance, all lanes for the East-bound travel will have some green marking, like an arrow, in lights. The marking going in the opposite direction would be a red “X” also in lights.
You’ll have a signal controller box which will handle the lighting, just like the signals at an intersection.
Should you appear at a cross-street, you can look in each direction and see green arrows or red "X"s, indicating which way you should turn.
Yes, it’s confusing. And yes, people from out-of-town will be upset and probably quite pissed off. Folks who are on auto-pilot may make a turn and then be faced with a tunnel of red "X"s and think, “Oh, shit!”
The folks who are commuting are happy they aren’t sidelined by construction.
The tax payers are delighted the politicians aren’t trying to pass yet ANOTHER bond measure to finance new highways.
