多年的建设实践表明，随着桥梁设计理论和实践的不断发展，人行天桥在交通中所起的作用逐渐受到了人们的重视，天桥不再仅仅是具有交通功能的构筑物，而是具有多种功能可能性的城市建筑物。人行天桥除了应发挥本身的功能外，还应保持与周围环境的协调性，从而提高行人通行的便捷性，打造优美的景观效果。目前，也有一些城市已经形成了较大范围的空中步道系统，更强调与周围环境的协调统一性，对人行天桥的景观效果提出了更高的要求，也赋予了人行天桥内容和形式上的新概念。为此，厦门市公路事业发展中心融合了多年来的人行天桥建设经验以及对城市人行天桥的造型思考，并汇总国内外相关资料，编写了《人行天桥造型与应用实践》，以期为人行天桥的建设提供参考及借鉴。
