One must consider two things when it comes to drawing these comparisons:

• Traffic often follows strict patterns.
• These two are peak examples of careful planning

The second extends from the first.

To stop a city from being crowded, you must plan for the flow of people.

To stop a chip-set from being crowded, you must plan for the flow of electricity and the data that rides on its current.

There must be paths, road and highways for the movement of goods. Circuits

There must be places like warehouses to store goods. Capacitors.

There must be a method for keeping track of the goods in storage, as well as logs for their movement from place to place. Transistors

There must be places to hitch your beast of burden so you can sort and offload goods by hand, thereby preventing bulky animals from blocking the smaller paths. Resistors

There must be a large space to allow for the transfer of goods. Microchip/Processor

...

If you think about it, it is only logical that both Civil Engineers and Computer Engineers would come up with comparable systems for the movement of goods and electrical impulses alike.

Ultimately, what abstract concept we are seeing manifest in both these images is the notion of Flow.

For things to move perpetually, there must be a cyclical flow. What goes around, must come around. Anything you seek to build that is intended to stay functional perpetually must adhere to the Rules of Flow.
