长江航路的改革与发展

航路改革是长江航运史上的一次革命,它规范了船舶航行秩序,大大降低了交通事故发生率,提高了通航效率。本文从航路改革的意义,作法,收益入手,重点对航路改革的发展进行了探讨,具有一定的实践指导意义。     

交通流数据质量检验方法

交通流数据目前对于交通相关研究具有很重要的参考和使用价值。交通流数据质量检验可以保证从数据源所获得数据的正确性和完整性,并为数据的管理和应用提供可靠的数据基础。交通流数据常见问题分为数据缺失、数据无效和数据时间点问题三类,针对这些问题,本文提出了一种交通流数据检验与修复方法。以北京市交通流数据为例,对本方法进行了分析与验证。结果表明此方法具有很好的实际应用效果。     

关于船长权力的思考

在船舶管理工作中,随着航运企业的营运市场化,必须改变传统观念对船长权力的思考,应以国际公约、规则和法律为依据,正确理解船长权力的界限,全面落实对船长的授权,保证船长具有适当的指挥资格;完全熟悉船公司的安全管理体系;能可靠地履行其职责。使船长能有效地实施船舶管理和安全运行。     

Vehicle sorting for platoon formation: Impacts on highway entry and throughput

Automated highway systems (AHS) are intended to increase the throughput and safety of roadways through computer control, communication and sensing. In the “platoon” concept for AHS, vehicles travel on highways in closely spaced groups. To maximize benefits, it is desirable to form platoons that are reasonably large (five or more vehicles), and it is also desirable to ensure that platoons remain intact for considerable distances. This paper develops and evaluates strategies for organizing vehicles into platoons at highway entrances, with the objective of maximizing the distance that platoons stay intact, so that they do not need to be regrouped into new platoons on the highway itself. Fundamentally, this entails grouping vehicles according to their destination. We evaluate various strategies in which vehicles are sorted on entrance ramps, with respect to platoon sizes, throughput and platoon formation time.     

建设项目交通影响程度模糊评价研究

交通影响程度评价是交通影响分析的决策依据。鉴于TIA涉及因素多定量描述困难等原因,提出了利用模糊评价方法求出项目的"交通影响度",选择合理的交通影响程度评价指标,建立两层评价指标体系,并以此为基础构造交通影响程度二级模糊评价模型。实例检验说明,采用模糊评价方法求出的项目的"交通影响度"符合审批结果。

Empirical analysis of hazard perception and driving behaviors among high school and college students on motorcycles in Phnom Penh,Cambodia

In Cambodia, motorcycle use has spread rapidly in recent years, and serious accidents involving motorcycles have increased. Motorcycle accidents involving young people are particularly common, and there are various issues concerning traffic safety. To understand the situation in Phnom Penh, Cambodia, we conducted a questionnaire survey on driving attitude and behavior of motorcycle users targeted at high school and college students and a video observation survey of motorcycle driving conditions. Based on the survey analysis results, we held a traffic safety workshop (WS) comprising practical skills and classroom learning centered on hazard anticipation. In this study, we conducted a statistical comparative analysis of driving behavior frequency on non-intersection intervals of arterial roads before and after the WS, based on observational results from video cameras mounted on motorcycles. The results showed that the WS effects were associated with a reduction in average travel speeds and changes in driving behavior, such as frequency of lane changing. Different responses to the WS were observed according to attributes, and thus, the relationship between the content of this kind of traffic safety WS and behavioral changes needs to be clarified and a more advanced traffic safety WS program developed.
