城市综合交通调查的规范与创新

城市综合交通调查在中国已有30余年的广泛实践,当前的信息化和大数据背景下正历经发展与变革.在分析城市综合交通调查现状问题的基础上,提出制定《城市综合交通体系规划交通调查导则》(以下简称《导则》)的必要性.从目标与总体框架、调查项目分类、术语定义、调查内容与问题选项分类、调查流程规范几个层面对《导则》的主要思想与关键内容进行解析.提出城市综合交通调查未来发展方向应是将信息化技术与传统调查手段结合,提高调查效率与质量,关注信息化手段未能涵盖的交通特征.     

An integrated assessment of alternative land-based passenger transport policies: A case study in Tenerife

Over recent decades, there have been numerous cases of land-based transport policies that have lacked clear and coherent strategies. This has not only hampered the resolution of issues like road congestion, but has also created new ones (e.g. strong social opposition to new train infrastructures). The absence of such strategies highlights the need for long-term transport policies with a wider vision of the issues, since land-based transport cannot be considered from just a technical perspective.The main objective of this article is to implement a participatory integrated approach to facilitate the understanding of land-based passenger transport governance issues on Tenerife, in the Canary Islands. Relevant policy issues and alternatives are identified by the stakeholders involved. The inclusion of stakeholders in the assessment process is crucial to frame transport governance issues appropriately and to define and assess plausible policy alternatives. This assessment process even included a final step of validation of the results by stakeholders to foster discussion among them about transport issues and policy alternatives.Finally, due to the obstructive role played by some stakeholders in influencing past transport policies, an analysis of possible coalitions among stakeholders is also discussed.     

基于数据融合的公交客流规模测算方法

公交客流规模测算往往存在调查成本受限和准确度要求较高的矛盾.提出基于公交IC卡历史数据与人工补充调查数据的数据融合测算方法,以准确推算公交客流规模.首先根据公交线路的基本属性,采用聚类分析方法划分线路类型,从每一类中选择具有代表性的线路.基于IC卡数据分析公交客流时变特征,运用有序样本聚类Fisher算法将线路小时刷卡量进行聚类分析.划分刷卡量相似时段,进而采用优化方法确定调查抽样率,确定相应的调查车辆进行人工补充调查,最终经过数据融合计算获得公交客流规模.基于上海市某辖区IC卡数据进行案例分析,测算得到三类公交线路的日均客流量.     

公路经营企业内部控制探讨

我国公路经营企业在内部控制方面存在内部环境不健全、风险意识不强、控制活动不力、信息沟通不畅、缺乏信息系统支持和内部监督弱化等问题.加强公路工程项目内部控制,需要采取强化意识、明确责任主体、完善制度、加强实施力度和人员教育等相应的措施.     

山岭重丘区公路选线探讨

山岭重丘区选线受地形、水文地质、路线交叉、公铁交叉等多种因素制约,线位的优劣是制约经济、合理、可行的重要因素。背景为山西省晋城市G207线过境段公路改线工程,结合项目选线过程中遇到的实际问题,提出本次选线的几点原则,通过不同线位的比较,最终确定较为合理、经济的线位,对类似工程项目具有一定的指导意义。

Implementation of interactive transit information kiosks at New York City transit facilities: Analysis of user utilization and lessons learned

Transit Traveler Information Systems (TTIS) comprise a wide range of technologies that transit agencies use to provide reliable and timely transit-related information to customers. The touch-screen interactive information kiosk is an example of these emerging TTIS technologies. This paper examines the implementation of interactive touch-screen information kiosks, known as “On the Go!” Touch-Screen Travel Stations, at Metropolitan Transportation Authority-New York City Transit (MTA-NYCT) facilities in 2011. It analyzes data from passenger intercept surveys, from the kiosks’ built-in application usage logs and from field observations to understand actual passenger utilization of the kiosks and to assess the implications for transit agencies. The field observations also made it possible to obtain a profile of kiosk users, which sheds light on the concept of the “digital divide.” The findings, presented as lessons learned, can help agencies elsewhere develop guidelines and effective strategies for implementing similar interactive transit information systems.
