INTERMITTENT CHIPPED MARKS ON THE ROAD

Obviously, the image is not mine.
I'm so amazed at our field, Psychology. It's powerful! Thanks to the human-factors experts in improving the driving environment. Grabe!

Thanks to the work of De Waard, Jessurun, Steyvers, Raggatt, and Brookhuis (1995)! They hypothesized that drivers would often reduce its speed when they are perceptually uncomfortable. Hence, you'll observe intermittent chipped markings on the road to penalize the speeding driver with uncomfortable noise which will reduce the average speed by 3 km/hr. This is an ample reduction of speed to increase safety.

You can read this on Michael Aamodt, 8th Ed. It's on the Appendix Part. (Oops, yes, hahaha I'm reading the appendix and there are summarize per chapter on his book at the end. Tip lang.)
