Traffic management
Objectives
Traffic management arose from the need to maximize the capacity of existing highway networks within finite budget and, therefore, with a minimum of new construction . methods , which were often seen as a quick fix ,required innovation solutions and new technical developments . many of the techniques devises affected traditional highway engineering and launched imaginative and cost effective junction designs .introduction of signal – controlled pedestrian crossings not only improved the safety of pedestrians on busy roads but improved the traffic capacity of roads by not allowing pedestrians to dominate the crossing point .
More recently the emphasis has moved away from simple capacity improvements to accident reduction ,demand restraint ,public transport priority ,environment and restoring the ability to move around safely and freely on foot and by pedal cycle .
Demand management
There has been a significant shift in attitudes away from supporting unrestricted growth in highway capacity .the potential destruction of towns and cities and the environmental damage to rural areas are not acceptable to a large proportion . Traffic management has , largely , maximized the capacity of the highway network ,yet demand and congestion continue to increase .
Highway authorities accept that they do not have a mandate to provide funds for large amounts of new construction .it is clear that , for the foreseeable future ,resources will not be available to provide for unrestricted growth in private vehicular traffic .traffic engineering alone cannot provide for sufficient highway capacity even with limited amount of new construction

交通管理 目标 来自交通管理的能力,必须最大限度地在有限的预算和现有的公路网,以最小的新建. 方法,通常被看作是一种快速、创新方法和新技术的发展需要. 许多公路工程技术设计和推出具有传统影响和成本效益的设计路口. 采用信号控制的行人过路处不仅改善行人的安全,而且对改善繁忙道路的交通容量道路不让行人穿越主宰点. 近期重点已从单纯的能力,以减少意外的改善,制约需求,公共交通优先、环境恢复能力和安全、自由走动,徒步行循环. 需求管理 有显着地改变态度支持远离公路的增长能力. 可能破坏城镇和农村的环境损害不能接受了相当大的比重. 交通管理,很大程度上提高了公路网的能力,但是,拥挤的需求不断增加. 高速公路当局承认他们没有任务,提供了大量新的建设资金. 很明显,在可预见的未来,将没有资源用于私人车辆无限制增长. 交通工程公路不能单独提供足够的能力有限,即使有新的建筑
