按照ISM／NSM规则建立安全管理体系,是航运界的普遍做法。在实行体系化管理的过程中,体系运行“两张皮”的现象一直困扰着广大安全管理者。文中从分析“两张皮”的现象入手,研究形成“两张皮”现象的根源,探索消除体系“两张皮”现象的方法。     

重庆市主城区自行车交通系统规划与实践

为了优化城市交通结构,探索自行车交通在重庆市的发展途径,对重庆市主城区自行车交通系统进行规划。首先,针对主城区的山地城市特征,从城市及交通发展特点出发,研究分析发展自行车交通系统的必要性及可行性。然后,提出＂服务特定区域,满足中短距离出行;接驳公共交通,完善出行网络＂的功能定位,以及＂两个网络＂（公共交通接驳网络、局部区域自行车出行网络）＂、一个特色＂（特色景观自行车线路）的发展模式。最后,提出重庆市主城区自行车交通系统规划方案并进行实践,为同类山地城市自行车交通系统发展提供了有益借鉴。

Sustainable mobility: Policy design and implementation in three Norwegian cities

The paper explores barriers for designing and implementing policies for the transition to more environmentally sustainable urban mobility, and strategies for overcoming these barriers in three Norwegian cities. Empirical data has been collected by interviewing key informants and analysing relevant documents. The findings show that there is broad political support for placing sustainable mobility high on the political agenda. Challenges appear when policy measures are designed and implemented. Cultural, legal, political, organisational, financial and knowledge-related barriers are identified. Many similar barriers are identified in the three case cities, but differences also appear. The results indicate that the size of the cities as well as the type of policy packages implemented are important factors, impacting both the type and strength of barriers. Several strategies for overcoming barriers have been implemented in the three case cities with success. The implementation of policy packages with a combination of “push” and “pull” measures is perhaps the most important strategy. In addition, using communication strategically and allowing for trials and step-by-step introduction of policy measures are success factors. Better methods for stakeholder involvement and planning tools for bicyclists and pedestrians may increase the acceptance of policy measures and speed up the transition toward sustainable mobility.     

通用机场政策文本量化分析

通用机场是综合交通基础设施网络的重要组成,阐释通用机场政策工具体系的类型与特征具有重要意义。本文构建了以政策工具为核心,以政策目标和政策执行为两翼的3*32分析框架。以2016年至2020年的40个政策文本为研究对象,剖析了政策工具的类型与特征,并对政策目标与政策工具、政策执行与政策工具展开了交叉分析。结果显示,环境型政策工具应用频率最高,供给型和需求型政策工具应用较少,政策工具结构存在明显失衡;政策工具主要服务于规范建设与运营和引导发展与创新政策目标,政策目标的均衡性不足;政策工具与政策目标的匹配度较低,政府购买、人才供给、资金支持等诸多行之有效的政策工具在具体目标中未得到充分应用。     

Panoramic and Personalised Intelligent Healthcare Mode

Although the development of national conditions and the increase in health risk factors undoubtedly pose a huge challenge to China's medical health and labour security system,these simultaneously promote the elevation and transformation of national healthcare consciousness.Given that the current disease diagnosis and treatment models hardly satisfy the growing demand for medical and health care in China,based on the theory of healthcare and basic laws of human physiological activities,and combined with the characteristics of the information society,this paper presents a panoramic and personalised intelligent healthcare mode that is aimed at improving and promoting individual health.The basic definition and conceptual model are provided,and its basic characteristics and specific connotations are elaborated in detail.Subsequently,an intelligent coordination model of daily time allocation and a dynamic optimisation model for healthcare programmes are proposed.The implementation of this mode is explicitly illustrated with a practical application case.It is expected that this study will provide new ideas for further healthcare research and development.     

Decision-making on Large Infrastructure Projects: The Role of the Dutch Parliament

Abstract

Validating microscopic traffic simulation models incorporates several challenges because of the inadequacy and rareness of validation data, and the complexity of the car following and lane-changing processes. In addition, validation data were usually measured in aggregate form at the link level and not at the level of the individual vehicle. The majority of model validation attempts in the literature use average link measurements of traffic characteristics. However, validation techniques based on averages of traffic variables have several limitations including possible inconsistency between the field observed and simulation-estimated variables, and as such the resulting spatial–temporal traffic stream patterns.

Due to these inconsistencies, this paper introduces a novel approach to the validation of microscopic traffic simulation models. A three-stage procedure for validating microscopic simulation models is presented. The paper describes the field measurements, experimental setup, and the simulation-based analysis of the three stages. The purpose of the first stage is to validate a benchmark simulator (NETSIM) using limited field data. The second stage examines the spatial–temporal traffic patterns extracted from the benchmark simulator versus those extracted from the simulation model to be validated (I-SIM-S). Different traffic patterns were examined accounting for various factors, such as traffic flow, link speeds, and signal timing. The third stage compares the aggregate traffic measures extracted from the subject simulator against those extracted from the benchmark simulator.
