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.

A global route planning method for intelligent vehicle is presented here based on the comparison,selection and development of classic figure search algorithms.In addition,the effects of traffic signs in road network are also be considered in the method,so to insure that any traffic laws such as steering or passing through is violated.With the testing results,the method in the paper can decide an effective(or shortest distance) and legitimate global route for intelligent vehicle's driving guide,and the algorithm is running efficiently enough to meet the real time need when it should work temporarily during vehicle driving.

The Coordinating Research Council, Inc. (CRC) is a non-profit corporation supported by the petroleum and automotive equipment industries. CRC operates through the committees made up of technical experts from industry and government who voluntarily participate. The four main areas of research within CRC are: air pollution (atmospheric and engineering studies); aviation fuels, lubricants, and equipment performance, heavy-duty vehicle fuels, lubricants, and equipment performance (e.g., diesel trucks); and light-duty vehicle fuels, lubricants, and equipment performance (e.g., passenger cars). CRC’s function is to provide the mechanism for joint research conducted by the two industries that will help in determining the optimum combination of petroleum products and automotive equipment. CRC’s work is limited to research that is mutually beneficial to the two industries involved, and all information is available to the public.

On February 18, 2014, President Obama directed the Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) to develop a second round of greenhouse gas (GHG) emission and fuel economy standards for medium- and heavy-duty trucks. The standards, which will affect trucks beginning with the 2019 model year, are to be proposed by March 2015 and finalized a year later. The standards will be the fourth set of GHG emission standards for mobile sources.

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.

We generate high-purity correlated and entangled photon- pairs at the telecom wavelengths in a cooled 10-meter highly nonlinear fiber (HNLF). In our previous project (contract no: FA8750-12-1-0136), we were able to generate correlated/entangled photon-pair using the highly nonlinear fiber in a counter-propagating scheme (CPS). With the HNLF at room temperature, we obtain coincidence-to-accidental ratio (CAR) approximately 26-30 and two-photon interference with visibility approximately 92%-93%. This is the best performance compared to the reported results in the literature on HNLF and Photonic Crystal Fiber (PCF) at telecom wavelengths. Unlike the PCF or microstructure fiber, the HNLF can be cooled at liquid nitrogen temperatures (77K) to suppress Raman photons. By cooling the HNLF, we expect to obtain a CAR approximately 130 and two-photon interference with visibility > 98%. We will verify the non-local behavior of high-purity HNLF-based entangled photon-pairs by making Bell's Inequalities measurements. We investigate the effect of multiple scattering on the telecom wavelength photon-pair. Our findings show that quantum correlation of polarization-entangled photon-pairs is better preserved than polarization-correlated photon-pairs in multiple scattering processes.

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.
