双子城的匝道仪表一直是最近对其有效性进行测试的对象，包括关闭它们八个星期。本文分析了几条典型高速公路在下午高峰时段有无匝道控制的结果。七项业绩计量：比较了流动性、公平性、生产率、消费者剩余、可达性、出行时间变化和出行需求响应。据发现，坡道米是特别有帮助的长途旅行相对于短途旅行。匝道控制，虽然通常有利于高速公路路段，可能不会改善行程旅行时间（包括匝道延误）。行程时间变化的减少包括坡道仪表的另一个好处。非工作行程和工作行程对坡道仪表的响应不同。结果是混合的，这表明一个更精细的斜坡控制算法，明确考虑斜坡延迟，是为了。
Ramp meters in the Twin Cities have been the subject of a recent test of their effectiveness, involving turning them off for eight weeks. This paper analyzes the results with and without ramp metering for several representative freeways during the afternoon peak period. Seven performance measures: mobility, equity, productivity, consumers’ surplus, accessibility, travel time variation and travel demand responses are compared. It is found that ramp meters are particularly helpful for long trips relative to short trips. Ramp metering, while generally beneficial to freeway segments, may not improve trip travel times (including ramp delays). The reduction in travel time variation comprises another benefit from ramp meters. Non-work trips and work trips respond differently to ramp meters. The results are mixed, suggesting a more refined ramp control algorithm, which explicitly considers ramp delay, is in order.
