The risk of motor vehicle crashes (MVCs) associated with on-the-job operation of motor vehicles or exposure to road traffic hazards affects millions of workers in the United States, and this risk cuts across all industries and occupations. MVCs are consistently the leading cause of worker fatalities, affecting workers who drive all types of motor vehicles during their work day . passenger cars, heavy trucks, fire apparatus, and many others. A wide variety of interventions may be applied to prevent work-related MVCs: administrative controls such as seat belt policies, distracted-driving policies, pre-trip vehicle checks, driver training, reduced travel, and fatigue management; and engineering controls such as more crashworthy vehicles, advanced driver assistance systems, or active safety systems. Questions remain as to which are the most effective interventions to protect workers from risks of work-related MVCs. Through strategic planning, research, collaborations with stakeholders, and communication of research results and prevention, the National Institute for Occupational Safety and Health (NIOSH) is working to ensure that recommended solutions to prevent work-related MVCs and resulting injuries are based on sound research and are clearly communicated to employers and workers. The NIOSH Center for Motor Vehicle Safety (CMVS) is the focal point for activities within the Institute that address this pressing occupational safety problem. The CMVS was designated in December 2010 to strengthen and sustain the Institute's research and prevention activities to reduce work-related motor vehicle crashes and resulting injuries. It is a 'virtual' Center through which researchers from across the Institute and external partners from government, non-governmental organizations (NGOs), academia, labor, and industry bring complementary expertise to identify crash risk factors, develop and evaluate workplace interventions to prevent crashes, and communicate the results to employers and other stakeholders. The NIOSH CMVS is guided by the vision that: All workers who are exposed to hazards of motor vehicle traffic while working have the highest possible levels of protection from the risk of motor vehicle crashes and resulting injuries. The primary purpose of the 5-year strategic plan for the NIOSH CMVS is to define the priority areas for research and prevention initiatives through 2018.

The performance of the aluminum alloy makes it the most popular lightweight materials for the automobile manufacturers.However,due to the disparity on the crystal structure,it has the higher springback values compared with steel.In order to solve the problem,we put forward a new springback compensation method based on displacement compensation principle and the principle of curved surface fairing design methods.Though full cycle simulation and calculate springback value for each working procedure,then generate the springback compensation surface.The method's practical application effect is good.

With the fast advance of communication technologies,there is an increasing demand of efficient operations in low-power roaming environment.Several protocols came into being successively,yet for special requirements in automobile roaming system such as low consumption,high performance and convenience,these protocols cannot achieve a proper balance between security and efficiency since these protocols pay more attention to a common network environment.In order to go out from the embarrassing situation,we commit to provide a secure and effective mutual authentication mechanism for automobile roaming scenario.Our protocol employs elliptic curve cryptography system to reduce computational and communicational cost.Moreover,we also take into account common attacks and give corresponding resist measures to ensure security.In summary,our protocol is suitable for automobile roaming scenario since it provides user's anonymity,mutual authentication and is more efficient.
