Community Perspectives Toward a Marine Reserve: A Case Study of San Felipe,Yucatán,México

San Felipe marine reserve, in Yucatán, México, is unique, and particularly suited for a case study because the local community created it without a mandate from higher levels of government. This article presents the results of a survey of local interest groups using the method of paired comparisons and rank correlation analysis, to reveal local judgments about the severity of damages to coastal habitats and the level of impacts of activities that cause the damages. The results show that fishers differ significantly from other interest groups in their rankings of the severity of damages to habitats and of impacting activities. These findings suggest that despite the overlapping interests in protecting the resources and the critical habitats, the different perspectives of local interest groups about the severity of damages must be considered in the management of San Felipe marine reserve.     

关于公交线路线形及对位编码的思考

把城市公交线路站点进行线性回归,将其归纳为纵线、横线、左斜线、右斜线和环(含弧)线,并对社区公交提出新的见解.同时采用了分线形按方位区间分别对位编码的方法,对普通的公交线路番号的每个代码赋予特定的含义,使其具有明确的线路走向和方位识别功能.还对“线形布线及对位编码法”在实施中可能出现的问题及应对措施提出了自己的意见.该...

移动式布料皮带机在双护盾TBM出碴中的应用

隧道TBM施工采用有轨运输方式出碴时,掘进过程中矿车卸碴布料涉及工序较多,且牵引列车编组的内燃机车持续运行会增加尾气排放,造成隧道内空气污染。应用于青岛地铁隧道施工的双护盾TBM的后配套配置了移动式布料皮带机,该皮带机可实现往复移动和正反向运行为矿车卸碴布料。对该移动式布料皮带机的工作原理、结构组成、移动方式、张紧方式和驱动方式等进行研究,并分析其应用效果。实践证明,该技术应用于TBM后配套出碴可行、实用,简化了施工工序并提高了工作效率。     

青岛地铁隧道双护盾TBM适应性设计及应用

为应对岩石地质条件下城市地铁隧道施工工况的特殊性,对应用于青岛地铁2号线的双护盾TBM进行适应性设计。盾体采用模块化设计并在前盾安装配合稳定器工作的辅助支撑,管片吊运直接由吊机喂送至拼装机,后配套出碴配置梭式皮带机,采用满足小转向半径掘进的双激光靶导向系统,从而保证隧道施工过程中装机、始发、掘进、出碴、过站、小曲线半径掘进和洞内拆机等工况的顺利实施,取得良好的应用效果。通过对施工过程中掘进参数、衬砌变形和地表沉降等应用效果的分析,验证了双护盾TBM选型的正确性和对青岛地质的适应性。     

A ‘placeful’ station? The community role in place making and improving hedonic value at local railway stations

In recent years, railway stations have come to be seen as non-places within society, points of transit and nothing more. The role of the station in place making is disputed with stations seen as both creating and destroying a sense of place within a community. Our study is located within the railway stations of Scotland and explores how local communities have been empowered to reclaim, customise, and re-appropriate stations to simultaneously create a sense of place and better promote their community to the outside world. Drawing on ethnographic research we refute the notion that stations are somehow ‘placeless’. We show how through a process of legitimisation, a sense of ownership and appropriation of the station environment, communities are able to transform the station, improving hedonic value and recapturing a sense of place.

Integrated smart feeder/shuttle transit service: simulation of new routing strategies

The idea of designing an integrated smart feeder/shuttle service stemmed from the need to overcome the problem of using an excessive number of cars arriving and parking at a train station within the same time span. This problem results in high parking demand around the train station. Moreover, some potential train riders will, instead, use their cars and hence become a party to increasing the traffic congestion. This work develops a new idea of an integrated and innovative feeder/shuttle system with new operating and routing concepts. The fulfilled objectives are as follows: (i) to construct and examine different operating strategies from both the user and operator perspectives; (ii) to examine different routing models and scenarios; and (iii) to construct a simulation tool for (i) and (ii). Ten different routing strategies are examined, with all the combinations of fixed/flexible routes, fixed/flexible schedules, a unidirectional or bidirectional concept, and shortcut (shortest path) and/or short‐turn (turnaround) concepts. These strategies are investigated by employing a simulation model specifically developed and constructed for this purpose. This simulation model is used in a case study of Castro Valley in California in which the feeder/shuttle service is coordinated with the Bay Area Rapid Transit service, and the 10 routing strategies are compared in regard to four fleet‐size scenarios. One of the interesting results found is that the fixed‐route and flexible‐route concepts are comparable in performance measures when applying a combination of operating strategies.
