After receiving a speeding ticket and taking an on-line driver’s safety course, I found a link in that course that took me to trafficwaves.org. Absolutely amazing! It describes how a single driver can completely destroy a huge traffic jam by putting some space in front of him before entering the jam. It talks about the wave patterns in traffic and many other things. The author of the site has single-handedly broken up many traffic jams already with these simple techniques. It’s also interesting that virtues such as patience and generosity are through this experiment shown to increase efficiency in traffic flow. It also shows how the vices of impatience and greed can cause a backward travelling wave of jammed cars behind him that can last for hours and it decreases the efficiency of the highway – so the most aggressive person in the jam is causing and increasing the jam and is slowing himself down without knowing it. Check out the site – it’s quite interesting!
