随着社会的进步,时代的发展,人们出行的节奏发生了巨大变化。古时候,人们不能想象也无法触及的大洋彼岸,当今社会通过先进的交通工具能够在较短时间内到达。这一切不只改变了人们生活的节奏,也同时改变了人们生活的环境。从汽车的普及开始,城市的所有道路都必须按照汽车行驶的需求来修筑。主干道的设计必须考虑到交通高峰期时的拥堵问题;各个路口也必须考虑到交通信号灯指示的问题;甚至当我们的城市规模过大而需要建设环城高速来缓解交通压力的时候,都无不体现出公共交通系统设计的重要性。比如90年代初的上海,地铁和都市环状高架建设完成,它们大大地缓解了上海的交通压力,起到了决定性的改善作用。城市的交通运转盘活了,城市的面貌也得到了根本的改变。但是只有道路没有标识的话,交通状况将会一片混乱。正是基于标识系统设计的良好易读性才使得整个交通系统井然有序。“有效和规范的公共交通导向系统是现代交通疏导的灵魂”。① With the progress of society and the development of the times, great changes have taken place in the rhythm of people’s travels. In ancient times, the other side of the oceans, beyond the reach of people’s imagination and reach, can be reached in a relatively short period of time by advanced means of transport. All this not only changed the pace of people’s lives, but also changed the environment of people’s lives. Starting with the popularity of cars, all roads in the city must be built to meet the needs of the car. The design of the main road must take into account the congestion problem at the peak of the traffic; all intersections must also take into account the problems of the traffic lights; even when the size of our city is too large and the construction of the high-speed around the city is needed to relieve the traffic pressure, Reflect the importance of public transport system design. For example, the completion of Shanghai, metro and metropolitan ring-shaped elevated buildings in the early 1990s has greatly alleviated the traffic pressure in Shanghai and played a decisive role in improvement. Urban traffic turntable alive, the city’s appearance has also been fundamentally changed. However, traffic conditions will be chaotic only if the road is not marked. It is the design of the logo based on the good readability makes the entire transit system organized. “Effective and canonical public transport-oriented system is the soul of modern transport ”. ①
