Hardback. Zustand: Good. 间断流 (Interrupted flow) 和非间断流 (Uninterrupted flow) 是道路交通系统的两大类问题。间断流问题多见于城市街道。为了保证安全，需要在道路相交处通过外部控制将各方向的车辆和行人在空间或时间上分隔开来。信号控制就是交叉口时间分隔最严格的表达方式，也是本书《信号交叉口》讨论的重点。非间断流问题多见于高速公路，它们常常是由于构成流体的内部原因例如车辆之间以及车辆与道路之间互动造成的。为了提高效率，需要发现瓶颈点、寻找拥堵的原因、了解拥堵发展的过程、以及解决拥堵的策略。这些就是作者另一本专著《交通流理论》讨论的重点。本书为高等院校交通工程专业提供一本交叉口信号控制方面的入门教材。它由浅入深、逻辑递进：从交叉口的由来到它的控制等级、从使用信号的理由到它的计算原理、从定时信号到感应信号、从低速交叉口到高速交叉口、从点控到联控。它侧重于交叉口信号控制的定量讨论。重点阐述了信号控制的基本原理，例如：为什么要使用信号？应该使用哪些信号阶段、这些阶段如何递进？各阶段如何配时？如何响应交通需求？如何动态调整信号？如何解决两难区问题？如何实施联控？通过学习本书，读者对于交叉口信号控制可以做到不仅知其然，还知其所以然&#12290. …
