Examining the linkages between electronic roadway tolling technologies and road pricing policy objectives

The surge of road pricing projects in the U.S. and around the globe over the past 15 years has been enabled by a variety of new communication and transportation technologies. While all of these technologies increase the efficiency of roadway tolling vis-à-vis manual collection, no “best” configuration has emerged. Rather, optimal configurations depend on the objectives of the tolling effort, such as facility type, geographic scope, desire to price externalities, integration with other operations, and so on. While such policy objectives for road pricing have been examined extensively, little has been written on the explicit links between tolling technology configurations and policy objectives. This paper addresses this gap in the literature through an examination of eight road pricing programs. For each program we evaluate the conduct of the three technical tasks via the nine technology sets in light of six principal policy objectives of road pricing.     

An evaluation of the user characteristics of an open access DRT service

The successful provision of Demand Responsive Transport (DRT) in Europe, Australia, UK and the US has been addressed in several substantial studies and projects. The general finding of these studies is that DRT is a suitable transport solution in particular areas and can deliver social inclusion and community building objectives. Existing research confirms that DRT is particularly useful for connecting isolated communities and population groups to essential services such as healthcare and is cost-effective in terms of contributing greatly to community wellbeing. However, many existing DRT services are still not performing to their true potential, and many of them could not be viable as commercial services. The aim of this study is to develop greater understanding of DRT services from the passengers’ perspective using a case study of LinkUp in Tyne and Wear, one of the most successful DRT schemes in the UK. The paper has two key objectives: (a) to critically review, in the context of the detailed case study the general characteristics of the selected DRT scheme; and (b) to analyse and interpret the findings from a detailed survey of users (who are predominately elderly and female) with regard to passenger characteristics, their attitudes and perception of the service and their suggestions for improvement.     

Social change and future transport policy in the Japanese context

Despite bringing many external benefits, economic growth has not solved all problems. In Japan today two problems seem to stand out: an aging population and the need to protect the population from natural disasters. The first problem has long been noted but the population is aging so fast that society seems incapable of adjusting properly to the new situation.     

An Extended Policy Language for Role Resolution in Project-Oriented Workflow

IntroductionIn recent years,increasing attention is beinggiven to ways of role resolution in the context ofworkflow systems[1～3 ] . The mechanism for assign-ing the activities to appropriate available users isreferred to as a role resolution. However,therestill exists no whole solution for complex role reso-lution such as Separation of Roles or Binding ofRoles and several exception situations such as RoleDelegation or Role Unavailable[3 ] .This paper intends to cast light on the man-ageme…

关于秘鲁鱼粉自热自燃原因的探讨

近来，秘鲁鱼粉在远洋运输过程中屡次发生自然事故。本文就这一现象从鱼粉的组成、性质、抗氧剂的处理程度以及运输积裁条件加以分析，阐述了鱼粉发生自燃的诸多原因。并根据实际案例、秘鲁当地对鱼粉抗氧剂处理过程的现状及商检部门的检测方法等方面的资料分析，指出了秘鲁鱼粉在运输过程中发生自燃的主要原因是鱼粉中的抗氧剂分布不均匀，致使那些抗氧剂浓度不足的鱼粉在运输途中抗氧剂含量逐渐消耗而发生氧化反应，产生大量的氧化热，达到鱼粉的自燃点而发生自燃。     

智能交通国际发展概况和国内优先考虑的课题

综述智能交通系统10年来在国际上的发展状况，讨论了我国研究开发智能交通系统的优先链。指出：在宏观上，我国应首先制定发展智能交通系统的战略规划以及相应的技术标准体系，以保证智能交通系统的兼容性、扩展性和互联性。并建议在我国及早成立智能交通协调机构，认为在我国优先发展的智能交通项目应首先考虑解决城市交通堵塞问题。     

土地相关政策研究对盘活既有铁路用地重要性的思考
