Roads at ground level must be laid out in more or less square grids. This requires us to drive at right angles to our intended direction of travel, and then wait at red lights for other cars also traveling at right angles to their intended directions. Gridlock is the result.
[kbecker] has proposed
making all roads elevated. This is a great advance but such roads retain the legacy property of directionality. Suppose the elevated road was built instead as a continuous omnidirectional driving plane.
To use the system the car would be driven manually to an on-ramp, and then put onto automatic guidance. All cars would travel across the surface in straight lines to the off-ramp nearest their destination, with only slight changes of speed and direction as required to maintain separation. The effect will be to produce an infinite number of virtual roads, each perfect for the individual vehicle. Cars will drive at their highest capable speeds as this minimizes the number of cars on the plane at any time.
A communication link will be needed between each car and the central computer, but the cost will be offset by the elimination of all traffic signals and markings.
The surface needn’t be completely unbroken; discontinuities will be mapped into the software for tall buildings and for windows to let sunlight into the chasms below.

You propose a roof over entire cities? A single elevated
road can screw up a whole neighborhood. This will screw
up everything under it. Traffic would be light, though,
because nobody would want to live in this town anymore. |

You mean this isn't a remixed Beatles album ? |

If we attach propellors to the roof of the cars then we can take advantage of another dimension entirely. An interesting alternative would be helium zepellins for everyone.
Would Air strips be elevated to allow the aero-planes to land or would they be phased out by the monumental success of the elevated onimroad-plane? |

isn't the exact opposite of this being baked for the last 20 years or so in Boston to the tune of 30Bil or so? Thank you, Teddy, on behalf of all US Taxpayers. |

As an alternative, the omniroad could be an omnitunnel - an enormous cavern underneath the entire city. The central computer would have to direct the cars around the cavern's roof supports, but that would be similar to how it derects them around tall buildings in the original idea. |

This one big road sounds like one big demolition derby. |

An automated road surfass? And who's going to design the software? Windows? |

Why? Most European towns and cities are anything but square grids. |
|
| |
European towns aren't square grids because they were designed before traffic was a consideration. That's why it's so painfull to drive in Europe. |

visit Coventry now thatis a city that has 1/2 the idea the carparks are on building roofs |

PRT would be a thousand times simpler, and do the same job. |
