The paper unpacks the planning process into its component parts: model, process, technique, and goals—the “good thing”. The
paper advances the concept that planning, policy-making, and organizational restructuring can be analyzed under the same framework.
Each of the four components is described and reductionist examples are presented to clarify the intention and to illustrate
the technique that the transport analyst teams employ in their work. The examples cover both successes and failures. They
point toward the enormous scientific task ahead for planning to become meaningful and relevant to the problems of today. Finally,
in the frame of the willingness to pay, the paper puts forward a case for an institutional framework for a financially autonomous road administration. Similarly
organized, administered, and managed entities are relevant also for other transport modes.

The success of any coastal zone management policy is dependent on, among other things, effective legislation and its enforcement. This article examines some possible legal constraints on the implementation of an integrated coastal zone management policy in Ireland. An introduction to the existing legal framework is provided, and the inconsistencies and ambiguities related, in particular, to jurisdiction and area of responsibility are highlighted. In particular the effect of land ownership and property rights on coastal zone management are examined with reference to two popular resort beaches in County Donegal, Ireland. While a revision of the relevant legislation is desirable, it is probably unrealistic; however, powers are available to the various institutions involved in coastal management that are currently unused. These are reviewed and their potential to improve coastal zone management is discussed. 相似文献

为落实《珠江三角洲绿道网总体规划纲要》的要求,珠海市制定了《珠海市城市绿道网总体规划(2010—2020)》(简称《规划》)。首先阐述了对绿道定义及分级的认识。然后,分析了珠海市独特的山水自然环境,提出绿道网规划建设应遵循的原则和理念,认为《规划》应坚持"三因""、三边"、"三不""、三化"的"四三"原则及"环山滨水、通廊串联、单元式使用"的规划理念。《规划》以区域绿道为依托,根据城市组团分布、生态格局、自然人文景观分布等,形成了"四纵、两横、二环、六岛"的绿道网空间结构,绿道长度达1 003.02 km。《规划》还将建设任务分年度、分辖区进行分解,以确保规划建设的可操作性。 相似文献
