请教达人:哪里可以找到Wardrop这篇论文?

John Glen Wardrop
John Glen Wardrop was an English transport analyst who developed Wardrop';s first and second principles of equilibrium.
The concepts are related to the idea of Nash equilibrium in game theory developed separately. However in transportation networks, there are many players, making the analysis more difficult than in games with small numbers of players.
Network equilibrium models are commonly used for the prediction of traffic patterns in transportation networks that are subject to congestion. The idea of traffic equilibrium originated as early as 1924, with Frank Knight.
In 1952, Wardrop stated two principles that formalize this notion of equilibrium and introduced the alternative behavior postulate of the minimization of the total travel costs.
Wardrop';s first principle of route choice, which is identical to the notion postulated by Knight, became accepted as a sound and simple behavioral principle to describe the spreading of trips over alternate routes due to congested conditions.
Wardrop';s first principle states: The journey times in all routes actually used are equal and less than those which would be experienced by a single vehicle on any unused route. Each user non-cooperatively seeks to minimize his cost of transportation. The traffic flows that satisfy this principle are usually referred to as "user equilibrium" (UE) flows, since each user chooses the route that is the best. Specifically, a user-optimized equilibrium is reached when no user may lower his transportation cost through unilateral action.
A variant on this is the stochastic user equilibrium (SUE) wherein no driver can unilaterally change routes to improve his/her perceived travel times.
Wardrop';s second principle states: At equilibrium the average journey time is minimum. This implies that each user behaves cooperatively in choosing his own route to ensure the most efficient use of the whole system. Traffic flows satisfying Wardrop';s second principle are generally deemed "system optimal" (SO). Economists argue this can be achieved with marginal cost road pricing.
The first mathematical model of network equilibrium was formulated by Beckmann, McGuire and Winsten in 1956.

回楼上,你贴的是wiki上的,可能只是文中的几句话而已,不是论文的全部啊?

52年的东西,还是会议论文,不好找了。不过这篇牛文被引率的确狂高:
[图书] Some Theoretical Aspects of Road Traffic Research
JG Wardrop - 1952 - Institution of Civil Engineers
被引用次数:523 - 相关文章 - 网页搜索 - 图书馆搜索
黄海军教授那里肯定有,我看他的多篇论文都引了这个。发邮件吧求助吧
