摘要

限速是出于某些目的:例如，节油和安全。本文证明没有一个是合理的。速度限制减少了道路容量，或者等价地说，相同的交通流量需要更多的道路。本文揭示了交通经济学家是如何误解交通流量曲线的，有些人甚至把它误认为供给曲线。

The Dis-Economics of Speed Limit

Speed limit is imposed for some purposes: oil saving and safety, for example. This paper proves that none is justified. Speed limit reduces road capacity, or equivalently stated more roads are needed for the same traffic flow. This paper shows how traffic economists have misunderstood the traffic flow curve, and that some even have mistook it as a supply curve.
