5981.路边/中央分隔带护栏的能量吸收器的使用评价
[水利、环境和公共设施管理业,交通运输、仓储和邮政业] [2015-07-21]
Several types of elastomeric energy absorbers were evaluated for use in a Manual for Assessing Safety Hardware (MASH) Test Level 4 (TL-4) energy-absorbing, urban roadside/median barrier. Twelve dynamic bogie tests were conducted on 60- and 80-durometer EPDM rubber cylinders. Five dynamic bogie tests were conducted on marine shear fenders. One dynamic test was conducted on a 27-ft (8.2-m) long installation of 2-in. (51-mm) thick EPDM rubber cylinders spaced at 8 ft (2.4 m) on center and attached to the front face of a 32-in. (813-mm) tall, concrete New Jersey-shaped barrier with a continuous 6-in. x 12-in. (152-mm x 305-mm) steel tubular front rail. One dynamic test was conducted on a 28-ft (8.5-m) long installation of 11.-in. (295-mm) tall marine shear fender posts spaced at 8 ft (2.4 m) on center with a 6.-in. (171-mm) tall, upper timber rail. Both barrier concepts showed promising results. Several static tests were conducted on the marine shear fenders at hot, cold, and room temperatures to evaluate its effect on energy-absorber behavior.

5982.交通部门的节能策略
[交通运输、仓储和邮政业,水利、环境和公共设施管理业] [2015-07-16]
Transit administrators, engineers, and researchers often face problems for which information already exists, either in documented form or as undocumented experience and practice. This information may be fragmented, scattered, and unevaluated. As a consequence, full knowledge of what has been learned about a problem may not be brought to bear on its solution. Costly research findings may go unused, valuable experience may be overlooked, and due consideration may not be given to recommended practices for solving or alleviating the problem.This study describes how transit agencies are reducing energy use and is based on survey responses from 51 diverse agencies across the country, a literature review of a variety of academic and professional publications, and case examples of four agencies.

5983.强海流的轮船航线选择

From the Surface Velocity Program (SVP) drifter current data, a detailed and complete track of strong ocean currents in the north-western Pacific is provided using the bin average method. The focus of this study is on the Kuroshio, the strong western boundary current of the North Pacific flowing northward along the east coast of Taiwan and then turning eastward off southern Japan. With its average flow speed of about 2 knots, the Kuroshio can significantly increase the ship s speed for a super-slow-steaming container ship travelling at speeds of 12 knots between the ports of Southeast Asia and Japan. By properly utilizing knowledge of strong ocean currents to follow the Kuroshio on the northbound runs and avoid it on the return trip, considerable fuel can be saved and the transit time can be reduced. In the future, the detailed Kuroshio saving-energy route could be built into electronic chart systems for all navigators and shipping routers.

5985.全球汽车租赁市场报告(2015-2019年)
[租赁和商务服务业,交通运输、仓储和邮政业] [2015-07-02]
Car rental services operate through a network of pickup/drop-off points and offer a range of vehicles that customers can pay to drive as and when required. Car rental is an alternative to car ownership. In this system, vehicles are owned by a firm or organization that rents them to users for short periods by the day or through monthly or annual plans. Over the past three decades, car rental has grown from a basic service provided by popular organizations to a widely recognized component of the urban transport industry. It is also quickly developing into a globalized industry that can provide many transportation, land use, environmental, and social benefits.
