A maritime safety on-board decision support system to enhance emergency evacuation on ferryboats

Planning emergency evacuation operations in a proactive manner in public marine transportation systems is a critical success factor for passenger and crew safety. Despite the fact that there is a growing attention on safety issues for marine transportation systems, providing a real-time decision support for evacuation planning under different emergency conditions has not yet been addressed. In this context, this paper contributes to the related literature by providing a comprehensive methodology including simulation and statistical analysis along with a three-module decision support system (DSS) for ferryboat emergency evacuation. Emergency evacuation and fire environment are simulated via Maritime EXODUS V5.1 and SMARTFIRE V4.3, respectively. The methodology is applied to a real-life Ro-Ro ferry, and the results not only revealed significant factors on emergency evacuation performance, but also demonstrated the validity of the developed decision support system.

The Dependency of People on the Great Barrier Reef,Australia

Understanding how people are dependent on Large Scale Marine Protected Areas (LSMPAs) is important for understanding how people might be sensitive to changes that affect these seascapes. We review how resource dependency is conceptualized and propose that it be broadened to include cultural values such as pride in resource status, scientific heritage, appreciation of aesthetics, biodiversity, and lifestyle opportunities. We provide an overview of how local residents (n = 3,181 face-to-face surveys), commercial fishers (n = 210, telephone surveys), and tourism operators (n = 119 telephone surveys) are potentially dependent on the Great Barrier Reef (GBR), a region currently experiencing significant environmental, social, and economic change. We found that commercial fishers and tourism operators were dependent not only financially on the GBR, but also because of their age, years in the industry and region, lack of education, and the number of dependents. These stakeholders lacked flexibility to secure alternative employment. All stakeholder groups, regardless of economic imperatives, were dependent on the GBR because of their cultural connections. We propose that resource dependency also provides an umbrella concept to describe the cultural services provided by an ecosystem, which can be described through place-based dependence and place-identity.

基于检修资源共享的现代有轨电车车辆基地规模测算及关键指标分析

结合相关城市在有轨电车车辆基地建设方面的经验,对现代有轨电车车辆基地规划关键性指标进行量化分析。针对城市土地资源紧张的特点,提出有轨电车规划中的资源共享理念,在网络阶段采用"集中检修分散停车"的规划方法。给出了车辆基地规模测算方法:按检修台位测算以及按有轨电车车辆停放规模测算,并将该理念与方法应用于深圳市龙华新区现代有轨电车线网实际案例中。结果表明,该方法在有轨电车车辆基地的选址规划,城市土地的集约利用,优化检修资源配置方面具有重要意义,可为城市交通相关规划和运营部门决策提供参考。
