Traffic jams are something nearly everyone can relate to. While driving is ideally a communal activity, where people pay attention to each other and follow the rules of the road, most people seem to follow their whims, only occasionally within the confines of common sense. This urge to do what is best for the individual leads to headaches for the group, increasing the total amount of time everyone has to spend on the road.
In a paper set to be published in an upcoming issue of Physical Review Letters, physicists Hyejin Youn and Hawoong Jeong, along with computer scientist Micheal Gastner, look at the result of self-interested drivers traveling on both hypothetical and real-world networks. The abstract describes what happens very clearly:
Uncoordinated individuals in human society pursuing their personally optimal strategies do not always achieve the social optimum, the most beneficial state to the society as a whole. Instead, strategies form Nash equilibria which are often socially suboptimal. Society, therefore, has to pay a price of anarchy for the lack of coordination among its members.
I find a couple major flaws in their analysis.
1. One can not quantify “the most beneficial state to the society as a whole.” The system is too complex. What usually occurs is people ignore or are ignorant of that which they are ignorant of. They ignore the unseen.
2. They mistakenly see the roads and those who drive on them as anarchistic. They are in no such way. The State has forced the road system onto the drivers. They force the licenses, the ‘public transportation’ methods, the HOV lanes, the one ways, even the design of cars through money and energy cost manipulations. The users are being directed. Just because X can take route 1, 2 or 3 does not mean they are free and surely doesn’t indicate any definition of anarchy.
As a result of this coercion the society, the market, is unable to work toward an optimal condition. State civil engineers decide what’s optimal based on their own beliefs without real responsibility. The entrepreneur road owner with a private civil engineer, with their business on the line and competition would find more efficient ways to provide their service incrementally and as a result of customer demand. Such as the analysis done by Youn, Jeong and Gastner.
Of course, issolated, lacking greater knowledge and an inability to change the structure of things will lead to less efficient systems. However, you will always have at least the first two… unless we become assimilated by the Borg. Individuals can only act on the information they have at any one time. Blaiming road congestion on the drivers because they are looking to optimize their route is missing the bigger picture completely. Forcing everyone into some computer calculated and controlled route will lead to (obviously) less freedom and all the ‘unseen’ resulting from that. Culling useless troublesome roads is a good idea but those who are in need of this fix are the problem in the first place. No matter how many of these discoveries they come across, government will always perform them inefficiently when compared to the natural flow of the market.
