Final answer:
Railroad tracks are like one-way streets because they allow vehicles to move in only one direction, promoting smooth and efficient movement.
Step-by-step explanation:
Railroad tracks are like one-way streets because they allow trains to move in only one direction, similar to how cars on a one-way street can only travel in one direction.
In both cases, the tracks or streets are designed to ensure smooth and efficient movement of vehicles.
For example, just like how cars on a one-way street can avoid collisions and traffic congestion, trains on railroad tracks can also avoid congestion and maintain a constant flow of traffic.
Additionally, railroad tracks, like one-way streets, have signals and signs to guide the train or car in the correct direction.
