Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the research period?Late 1950s
2. What is the publication year?1964
3. Why do cars that go too fast or too slow have more accidents?Cars that are much faster or slower than most cars are harder for other drivers to predict, so they can cause crashes.
4. How does the Solomon curve help make roads safer?It shows that keeping cars around the average speed reduces accidents, so it helps decide speed limits and road designs.

Collision rate: A statistical measure indicating the frequency of accidents per unit of exposure (e.g., per vehicle-mile).
Average speed: The mean speed of vehicles operating on a specific road segment at a given time.
Confounding variables: External factors that can influence both the independent and dependent variables in a study, potentially distorting results.
Traffic calming: Measures designed to reduce the speed of vehicles and improve safety for pedestrians and cyclists.
