在只有有限的道路通往市中心时 ,城市交通最为顺畅。这个有悖直觉的发现或许能让规划者们通过关闭而不是修建道路来防止堵车。这个发现来自津大学的尼尔·约翰逊、道格拉斯·阿什顿和蒂莫西·贾勒特对复杂网络系统的新思考。三位研究者先用一条环线和若干条在中心交汇的干线模? With only limited access to the city center, the traffic is smoother. This paradoxical discovery may allow planners to prevent traffic jams by shutting down instead of building roads. The discovery comes from Nean Johnson, Douglas Ashton and Timothy Jarrett, of Tianjin University, who are new to complex network systems. Three researchers first use a loop and a number of center lines in the intersection?
