5891.三个挪威承运人公司的安全文化调查
[交通运输、仓储和邮政业,信息传输、软件和信息技术服务业] [2015-07-30]
The report presents the results of a survey of safety culture in three Norwegian haulier companies, which are selected based on an assumption that they have good safety culture. The study supports the assertion that the companies have good safety cultures. This especially applies to Company A, which has the highest safety culture score of the three companies, and which also have a higher safety culture score than we have found in other transport sectors. This is probably due to the fact that Company A transports dangerous goods, which is a line of transport which has particular framework conditions favoring safety. The accident involvement of the drivers were in accordance with the companies score on the safety culture index. Analyzing the data on the three companies work on safety, we have identified the following common characteristics of good safety work in haulier companies: 1) Follow up of drivers speed, seat belt use and driving style, 2) Managers and employees safety commitment, 3) Predictability, 4) Organization of transport assignments, 5) Pay system, 6) Control of drivers compliance with regulations related to drive and rest, 7) Safety training/education, 8) Arenas for communication about safety, 9) Reporting culture and systems, and 10) Safety management system: a) risk analyses, b) procedures, c) training.

5892.高速公路车辆火灾(2008-2010)局部火灾报告系列
[交通运输、仓储和邮政业] [2015-07-30]
From 2008 to 2010, an estimated 194,000 highway vehicle fires occurred in the United States each year resulting in an annual average of approximately 300 deaths, 1,250 injuries and $1.1 billion in property loss. These highway vehicle fires accounted for 14 percent of fires responded to by fire departments across the nation. Highway vehicle fires include fires in passenger road vehicles (e.g., cars, motorcycles and off-road recreational vehicles), freight road transport vehicles (e.g., dump trucks, fire apparatus and tank trucks), and agricultural and construction vehicles. This topical report addresses the characteristics of highway vehicle fires reported to the National Fire Incident Reporting System (NFIRS) from 2008 to 2010.

5893.增加损坏驾驶执法能见度:六个案例研究
[公共管理、社会保障和社会组织,交通运输、仓储和邮政业] [2015-07-30]
Research has shown that an effective way to reduce impaired driving is to increase the perceived risk of being stopped and arrested by law enforcement if driving while impaired. One of the most successful strategies for doing this is the coupling of intense and highly visible enforcement with publicity about the enforcement campaign. The term high-visibility enforcement (HVE) is used to describe law enforcement efforts aimed at deterring unsafe driving behavior by increasing the public's perception of being caught, arrested, and prosecuted. Two common enforcement strategies of HVE operations are sobriety checkpoints and saturation patrols. Checkpoints concentrate law enforcement officers at the roadside to identify impaired drivers passing through. Saturation patrols involve an increased number of officers patrolling a limited area where impaired driving is prevalent. Both use highly visible elements (such as a concentration of law enforcement officers, bright lights, signs, and marked patrol cars) to heighten their visual impact. Enforcement efforts must be supported by an equal amount of publicity and communications.

5894.全球民用航空模拟培训市场报告(2015-2019年)
[信息传输、软件和信息技术服务业,交通运输、仓储和邮政业,教育] [2015-07-25]
A civil flight simulator is a device that artificially recreates aircraft flight and various aspects of the flight environment. The flight simulator is used for pilot training on civil and military aircraft. There are two types of training: Initial training for new pilots and recurrent training for existing pilots.

5896.基于信息融合方法的对车辆危险的旅行状态的研究评价
[交通运输、仓储和邮政业] [2015-07-22]
An evaluation system of vehicle traveling state was proposed,and an unsafe vehicle traveling state recognition system was established using multi-level information fusion method.In view of the effects of the complexity of the driving environment,a variety of working conditions and the diversity of vehicle traveling characteristics,combing BP neural network with Dempster Sharer evidence theory technique,the multi-information decision-level fusion was proposed to estimate the different kind model of the vehicle status.To verify the proposed strategies,the vehicle traveling posture evaluation system was established.The lane departure parameters and the relative distance parameters were studied in order to get the characterization of the vehicle traveling status information.The simulation results indicate that the adaptability and accuracy and the intelligence level of driving characterization estimation are significantly improved by using the pattern classification and decision technology of multi-source information fusion.

5897.模态转变和高速公路:当今现状综述
[交通运输、仓储和邮政业] [2015-07-22]
This report provides a review of scholarly literature with direct relevance to the topic of modal shift and high-speed rail (HSR). HSR systems are usually planned on the expectation that they will attract riders who would have chosen other modes (such as air, automobile, bus, etc.) had the HSR not been created. Identifying and measuring the actual ability of HSR to effect modal shift is therefore critical. This report examines the evidence concerning HSR and modal shift in both secondary analyses of previous studies and in newer studies that use primarily original data. The studies that were reviewed comprise a large variety of HSR systems, time periods, data sources, and means of analysis.

5899.基于卡尔曼滤波算法对带有雷达的目标车辆运动状态估计方法
[交通运输、仓储和邮政业,信息传输、软件和信息技术服务业] [2015-07-22]
In this paper,based on Kalman filtering algorithm,a method of target vehicle motion state radar estimation with radar(or lidar) is presented.The state equations is established based on rigid plane dynamics theory,and then with a Kalman filter to do radar data processing,the position,velocity and acceleration of the target vehicle can be estimated at the same time,so that to cover the shortage that acceleration information can not be gained with radar system.Through simulation and field tests it is verified that the detection accuracy of position and velocity of target vehicle is increasing,and the acceleration of target vehicle can be estimated effectively and accurately.

5900.交通运输领域智能系统介绍
[交通运输、仓储和邮政业] [2015-07-22]
Urban mobility is not only one of the pillars of modern economic systems, but also a key issue in the quest for equality of opportunity, once it can improve access to other services. Currently, however, there are a number of negative issues related to traffic, especially in mega-cities, such as economical issues (cost of opportunity caused by delays), environmental (externalities related to emissions of pollutants), and social (traffic accidents). Solutions to these issues are more and more closely tied to information and communication technology. Indeed, a search in the technical literature (using the keyword "urban traffic" to filter out articles on data network traffic) retrieved the following number of articles (as of December 3, 2013): 9,443 (ACM Digital Library), 26,054 (Scopus), and 1,730,000 (Google Scholar). Moreover, articles listed in the ACM query relate to conferences as diverse as MobiCom, CHI, PADS, and AAMAS. This means that there is a big and diverse community of computer scientists and computer engineers who tackle research that is connected to the development of intelligent traffic and transportation systems. It is also possible to see that this community is growing, and that research projects are getting more and more interdisciplinary.
