6151.基于计算机视觉的城市交通自动控制研究
[交通运输、仓储和邮政业,信息传输、软件和信息技术服务业] [2014-07-24]
Urban traffic control is not only a real-time control system but also random,non-line ar,uncertainty complex system; the article discusses the use of PLC (programmable logic controlle r) control technology and fuzzy control method for traffic signal control system and how to complete the complex traffic control by using communications link technology between comp uters and application of fuzzy control theory,make vehicle and road navigation to realize intelligent.

6153.交通流检测的新型视频检测系统
[交通运输、仓储和邮政业,信息传输、软件和信息技术服务业] [2014-07-20]
A prototype of video detection system applied to traffic flow inspection is developed,which uses CMOS linear image sensor with high resolution 2K pixels and wide dynamic range as the core of imaging device.It combines FPGA with DSP as the core of acquisition and processing of massive image data.Moreover,a novel multiscale and hierarchical clustering algorithm for image segmentation is presented.Based on the theory of graph spectral,the algorithm can construct a new graph by analyzing the feature of an original image at different clustering scales,so that image (gmentation) can be accomplished easily to segment the image.The simulation results show that the (scan) speed of this system can reach to 1000 lines per second,the resolution being 2048 pixels.

6154.市区电动汽车充电站的规划
[交通运输、仓储和邮政业] [2014-07-20]
With respect to the planning problems of electric vehicle charging stations in the urban area,the paper presents a planning model which considers the road network structure,vehicle flow information,distribution system structure and capacity constraints,etc.Under the relative constraints of distribution network,the model selects the station sites and plug-in locations with the objective of minimizing the sum of users' wastage cost on the way to the charging station and the investments of station lines,realizes the auto-partition of station service areas by the weighted Voronoi diagram,and also optimally allocates the station capacities based on the queuing theory.Finally,considering both the benefits of the power company and the electric vehicle users,the planning program optimization is finished by minimizing the costs of the whole society.The case studied shows that the presented methods and models are to some extent practical and reasonable to the optimal planning of electric vehicle charging stations in the urban area.

6155.行业月度报告-物流201405
[交通运输、仓储和邮政业] [2014-07-18]
5月,受天气影响,物流业务总量指数有所回落至55.2%,仍处于较高水平。其中,运输型物流企业回落,而仓储型物流企业有所回升,意味着当前经济回暖仍处在由生产端向消费端传导的过程。此外,1~5月,交通运输、仓储和邮政业累计完成固定资产投资12143.98亿元,同比增长21.9%,扭转了自年初以来增速持续下滑的趋势。未来,我国物流行业仍将保持平稳发展:与居民消费相关的物流子行业将维持高速增长;资源类行业复苏乏力,将拖累大宗商品物流增速放缓;海运低迷,物流服务价格将继续回落。

[住宿和餐饮业,交通运输、仓储和邮政业,租赁和商务服务业] [2014-07-18]
5月,台湾入境旅客人数大幅增长,但同期港澳入境旅客人数出现一定程度下滑,全国入境旅游人数达1062.83万人,同比减少0.2%。但受益于经济型酒店平均房价有所提高,旅游外汇收入实现较快增长。当月旅游外汇收入43.87亿美元,同比增长3%。
2014年,人民群众日益增长的常态化的旅游需求将持续发酵,成为旅游市场的基础支撑。新型城镇化提出以及服务业发展需要寻求增长新动力,旅游业也再迎政策利好。预计下半年,我国旅游市场总体将保持平稳快速发展。

6159.2014年7月上半月港口航运业要闻综述
[交通运输、仓储和邮政业] [2014-07-18]
《中国交通报》7月1日报道,交通运输部7月1日印发《港口安全设施目录》(以下简称《目录》),对码头区安全设施、库场区安全设施、辅助生产区安全设施、消防安全实施、安全标志、个体防护安全设施进行了系统性规范。作为《港口法》、《港口危险货物安全管理规定》的配套文件,《目录》圈定了港政部门安全设施的管理范围,填补了该领域此前无统一明确规范的空白。
