[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.

5973.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.

5974.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.

5976.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.

5977.管理通道中免除交通工具的影响研究
[交通运输、仓储和邮政业] [2015-07-22]
In order to better utilize available capacity in high-occupancy vehicle (HOV) lanes, states are permitted to allow certain qualifying non-HOVs to use HOV lanes. In general, states may allow motorcycles, public transportation vehicles, high-occupancy toll (HOT) vehicles, and low-emission and energy-efficient vehicles to use HOV lanes. For any or all of these types of vehicles, the states must establish programs addressing candidacy, enrollment, and management of the lanes. In the case of tolled vehicles, dynamic pricing is the primary control that limits the potential to cause congestion in the lanes. In the case of the energy-efficient vehicles, the programs typically include decals, licenses, license plates, or stickers, that serve to identify and, in some cases, cap the number of allowed to use the lanes vehicles.

5978.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.

5979.2012年用户限制使用情况:基于交叉研究的国际化用户保护使用调查结果
[交通运输、仓储和邮政业,公共管理、社会保障和社会组织] [2015-07-21]
This report presents results from the 2012 National Occupanst Protection Use Survey (NOPUS) Controlled Inter-section Study. NOPUS is the only nationwide probability-based occupant restraint use survey. The National Center for Statistics and Analysis of the National Highway Traffic Safety Administration conducts this survey annually. The 2012 NOPUS found that male seat belt use increased significantly (up to 84 percent in 2012 from 81 percent in 2011) and that female seat belt use increased significantly (up to 88 percent in 2012 from 86 percent in 2011). Seat belt use among occupants age 25-69 years old increased significantly (up to 87 percent in 2012 from 84 percent in 2011). Restraint use for children in vans and SUVs decreased significantly down to 94 percent in 2012 from 97 percent in 2011. Seat belt use in rear seats stood at 75 percent in 2012.

5980.死亡评估和控制评价报告:伊利诺斯州州际高速公路连环车辆碰撞现场的志愿消防员死亡情况
[公共管理、社会保障和社会组织,交通运输、仓储和邮政业] [2015-07-21]
On March 5, 2013, a 39-year old male volunteer fire fighter was struck and killed by an enclosed car hauler with trailer (used to haul luxury vehicles) on an interstate highway. The fire department was operating at the scene of a multiple vehicle crash when a fire department pumper, a fire department utility vehicle, and an Illinois State Police vehicle were struck by a car hauler. The fire department was preparing to clear the original incident when this incident occurred. Utility 105 (fire department utility vehicle) was initially positioned approximately 1/2 - 3/4 mile from the incident blocking the left lane of the interstate. The Incident Commander radioed Utility 105 to move behind the state police vehicle. The car hauler was approaching the scene in the left lane and failed to stop for the initial incident. The victim was leaning against the rear passenger seat on the driver's side of Utility 105 with the door open. Members of the fire department were in the median of the interstate and witnessed the car hauler approaching the crash scene at a rate of speed that was excessive for road conditions. Realizing the car hauler was not going to be able to stop, members yelled for everyone to get out of the way of the car hauler. The victim moved away from the utility vehicle. He was struck by the car hauler and pushed onto the shoulder of the interstate. After striking the victim and the utility vehicle, the car hauler struck the state police vehicle and then struck Engine 102. After the crash scene was secured, the Incident Commander initiated a personnel accountability report. Utility 105 was located in the median between a trailer from the initial crash and the car hauler. The victim was located by a state trooper and was unresponsive. Despite receiving cardiopulmonary resuscitation (CPR) and basic life support (BLS) at the scene, and advanced life support (ALS) in the ambulance and in the local hospital's emergency department, the victim died.
