Why Cost Benefit Analysis is perceived as a problematic tool for assessment of transport plans: A process perspective

Academic discussions on Cost Benefit Analysis (CBA) as an appraisal instrument for integrated land use and transportation plans tend to focus on its technical aspects. However, many issues of CBA also arise from process related matters, especially when assessing integrated plans. Using an inductive research design, we explored how these process related issues play out in Dutch planning practices. In two applied research techniques, focus group sessions and open in depth interviews, we focused on process related issues as perceived by CBA participants ranging from plan makers to CBA testers. This article presents the different perceptions of issues in CBA processes. Through these collected perspectives, we found that these issues are multi-layered and present a number of fundamental dilemmas. After relating our empirical data to theory, we conclude that the biggest challenge lies in decreasing the level of mistrust and communication deficits revealed between plan owners and CBA calculators and their respective frames of thinking when assessing complex integrated land use and transportation plans.

近年国内常用非开挖施工技术施工方法综合概述

与传统开槽施工技术相比,非开挖技术可以使管道施工造成的的环境问题、社会问题和交通问题的影响程度降到最低。因此,非开挖技术广泛应用于铺设新管线、修复置换旧管线、探测原有管网等方面。其施工方法主要有水平导(定)向钻进铺管法、顶管铺管法、盾构铺管法、气动矛铺管法、无缝衬装置换法、管道翻衬置换法和爆(碎)管衬装置换法等。该文对近年我国常用的非开挖施工技术、施工方法,以及部分应用实例作了阐述。

Is the bus transport contracting system in South Africa leading to trusting relationships between contracted parties? An analysis of funding issues and the impact on relations between government and operators

The 1996 South African White Paper on National Transport policy provided the guidelines for the restructuring of the commuter bus industry. The restructuring objectives were based on improving the competitiveness of and service levels within the industry through a competitive tendering regime, the selective implementation of negotiated contracts and the general transformation of the industry to also include improved transparency in the funding arrangements between government and operators.In order to set the context of the paper, a brief overview is provided of the progress made with policy implementation and the background to funding issues that are experienced in the bus transport sector. To gauge the impact of the funding issues on the relationship between government and operators, a survey of the largest contracted operators was undertaken to determine, amongst other, how these funding issues have potentially impacted on trusting relationships between contracted parties.
