Question

Evaluate the effectiveness and ineffectiveness of speed humps in reducing road accident

Answer 1

Answer:

Explanation:

Speeds humps are oval cylindrical structures made with cement and tar on roads to prevent over-speeding. They are effective as any driver who drives his/her car above the speed limit can see it from a far distance and will eventually reduce his/her speed otherwise the car will hit the speed humps underneath its body causing damage to the car or a shock to the car and its driver with a sound is produced. But this little step is not enough to prevent over-speeding as rash drivers do not care about this. They still enjoy the thrill of it regardless of the shock and sound.

Effectiveness. Generally, vertical treatments - such as speed humps - are expected to reduce accidents by around 44%. Motor vehicles are likely to travel at around 15 mph over a speed hump. If there's a series of speed humps, vehicles are likely to travel at 20 mph between them.

Answer 2

Speed humps are intended to reduce driver speeds down to 10–15 miles per hour over the hump, and 25–30 miles per hour between humps in a series. ... Several studies from the Iowa Department of Transportation have shown a 40 percent speed reduction for most vehicles.
