今天的交通工程行业并没有有效地履行其主要使命。本文将讨论该行业当前的问题领域、这些问题领域所加剧的问题、出现的一些有缺陷的干线和走廊规划流程，最后将提出拟议的解决方案。我相信我们的专业需要更新并改善交通工程的地位和状态。全国范围内有一些证据表明存在这些问题。 2007年，国家交通运营联盟（NTOC）准备了国家交通信号报告卡。该联盟对公共机构对交通信号维护和运营的整体管理给予了 D 级评价。等级如此之低是因为大多数机构没有对交通信号维护和运营进行主动管理。它与 2005 年准备的成绩单几乎相同，但一些机构显示出改进（NTOC 2007）。我们正在用最少的资源灭火。部分问题可以追溯到交通工程行业缺乏知识和宣传。资源的小幅增加就可以显着改善交通信号运营。德克萨斯州交通研究所编制的 2009 年城市交通报告指出，“拥堵是美国 439 个城市地区面临的一个问题，而且在各种规模的地区，情况都在恶化。2007 年，拥堵导致美国城市居民出行时间增加了 42 亿小时，并额外购买了 28 亿加仑燃油，拥堵成本高达 872 亿美元，比过去十年增加了 50% 以上。” （施兰克和洛马克斯 2009）。我们正在为交通工程行业的运作方式付出沉重的代价。
The traffic engineering profession today is not doing an effective job of fulfilling its primary mission. This paper will discuss current problem areas within the profession, issues being exacerbated by those problem areas, some of the flawed arterial and corridor planning processes occurring, and, finally, proposed solutions will be presented. I believe our profession needs renewal and to improve the status and state of traffic engineering. There is some evidence of these problems nationally. In 2007, the National Transportation Operations Coalition (NTOC) prepared the National Traffic Signal Report Card. The coalition gave a grade of D for the overall management of traffic signal maintenance and operations by public agencies. The grade was so low because most agencies having no proactive management of traffic signal maintenance and operations. It was nearly identical to the report card prepared in 2005, with some agencies showing improvement (NTOC 2007). We are fighting fires with minimal resources. Some of the problem can be traced to a lack of knowledge and advocacy by the traffic engineering profession. A small increase in resources could make a dramatic improvement in traffic signal operations. The 2009 Urban Mobility Report prepared by the Texas Transportation Institute reported that “[c]ongestion is a problem in America’s 439 urban areas and it is getting worse in regions of all sizes. In 2007, congestion caused urban Americans to travel 4.2 billion hours more and to purchase an extra 2.8 billion gallons of fuel for a congestion cost of $87.2 billion—an increase of more than 50% over the previous decade.” (Schrank and Lomax 2009). We are paying a heavy price for how the traffic engineering profession is being conducted.
