This circular transportation network is on average shorter from any point to any other point ​than an equivalent size grid network. And also (as shown in the picture below) has no stop-start intersections, reducing energy spent and saving time and stress. The circular transportation network is also for internet cables and potentially for energy. Though household energy production might work out to be more efficient than a network.

The central section of the intersection is a bridge or tunnel to allow animals to pass from one nature place to the other.

With everything we need less than 4 km of where we live for 73.4% and 5.6 km for 100% of the population. Walking, cycling, e-bikes and mobility scooters are ideal for day to day needs. For the occasional long journey a faster transportation system may be needed. It could be a single rail with bike like vehicles connected together to make a people powered bike train or even a wind tunnel. Or maybe we will be happy travelling more slowly.
