Final answer:
The smoothest traffic flow on a road with three or more lanes tends to be in the middle lane(s), which offer a balance between merging and fast-moving traffic. For a rabbit crossing such a road, safety depends on various factors including lane usage and traffic conditions.
Step-by-step explanation:
When discussing traffic flow in a roadway system with three or more lanes in one direction, understanding motion in one dimension is essential.
Typically, the middle lane(s) provide the smoothest traffic flow as they offer a balance between the merging traffic of the right lane and the faster-moving vehicles in the left lane.
To address the specific scenario of a rabbit crossing, if a rabbit must cross a freeway that’s 3 meters wide per lane, it would need to cross a total of 9 meters if there are three lanes.
Timing this endeavor would depend on the rabbit’s speed. If a car is traveling in the lane furthest from the rabbit, the likelihood of the rabbit crossing safely increases.
However, the safety of the rabbit also highly depends on traffic conditions and the rabbit's own awareness and speed.
