Fig. 3 Safety Index Considering Aleatory Uncertainties Minimum LCC Assessment for Optimal Design The target of structural design is to minimize the total investment cost while keeping up the safety during life cycle.
The optimal safety level was examined to the beta when the expected LCC becomes minimum.
Damage cost was composed of the slight or serious cost item and the accidents, and it mostly comprises the economic loss resulting from the loss of life and the traffic closed or limited.

At the same time, China's expressway operation and management is lagging behind in the face of meteorological geological disasters, major traffic accidents, holidays minibus free passage and other emergencies, and especially lack the ability to deal with emergencies, which restricts the operational efficiency of the road network.
National highway video surveillance networking platform is mainly used to improve road traffic accident emergency handling ability and the public services level.
National highway video surveillance networking platform should be achieved, which is fully functional, easy to use, safety and stable.

The truck traffic also shows a single peak in the middle of the day, in contrast to the typical double peaks of general traffic patterns.
Truck traffic is heavier during the weekdays than on weekends, indicating the freight movements still conform to the business activities.
It can be seen clearly that truck traffic volume is a dominant variable.
It was found that at most sites, heavier trucks operated during the daytime and there was a ‘plateau’ peak of truck traffic in the middle of the day.

EDI in e-commerce application and safety measures Liu Dan Wuhan Biological Engineering College of Computer and Information Engineering Wuhan,China e-mail:15694270@qq.com Keywords： EDI; E-commerce; security; Legal Abstract：The science and technology, information industry, the development of sudden flight, so that means of transaction in international trade and method of the emergence of new forms, a variety of commercial institutions to establish electronic communications between the handling of the relationship between business activities and speed up the supply-side processing speed.
Currently, the developed countries and some developing countries in Europe and America, EDI has become the most basic means of foreign trade and contact, are widely used in trading companies, customs, commodity inspection, banking, transportation and insurance sectors or industries, and has achieved huge economic benefits to its users at an annual growth rate of 40%, as a new type of trade, EDI has begun to become a leading international trade.      
More familiar for both sides, more business, the case of a large amount of data communications, can be a virtual private network VPN, dedicated agreed by the parties encryption and authentication algorithms, re-set on the IP datagram packet and ESP header and the latter part of All the inner IP data encryption, which in both the internal network to establish an encrypted tunnel between security gateways, both to ensure data security, and simplify the mutual authentication complexity and unfamiliar for both sides, business exchanges less data traffic is relatively small, the true identity of identity not only includes the identification, but also on the credibility of the confirmation, CA certificate should be the core encryption and authentication system to ensure data transmission security.
Conclusion In short, EDI standardization of data packets through the realization of the automatic generation of business documents, transport processing, you can use VPN or a CA certificate-based encryption and authentication system to ensure their safety, and only really, really involved to solve the legal EDI questions to EDI technology as the core e-commerce will be a healthy development.

Introduction Air pollution caused by road traffic has been one of the major problems in our urban areas.
In despite of the requirements of intensifying emission control and the increasing installation of emission reduction systems, the continual traffic growth has raised more concerns over the effect of traffic emissions on human health and urban environmental quality.

ITS can effectively use existing traffic facilities, reduce the traffic load and environmental pollution, ensure traffic safety, enhance the transport efficiency.
Typical applications include e-Plates plan in England and Berlin traffic information collection plan in Germany.
RFID can be used in the urban traffic network or highway network monitoring. as a processing platform of spatial data, GIS can fuse real-time traffic information acquired by RFID and achieve management of objects logistics in the future.
Recently, International Standardization Organization(IOS) has announced a new standard of RFID for supply chain applications, which will help manufacturers track products better.

Road safety is of high importance in our modern life in terms of social and economic.
Introduction The traffic accidents, major public health problems, are one of the leading causes death and traumatisms in the world.

The Administrations are responsible for maintenance and repair of less important roads and roads with not so dense traffic.
Each criterion is viewed in terms of four aspects: § transport connections (a wide transport context, hierarchy, accordance with the Master/Zoning Plan), § building and technical condition of the roads and facilities, § operating characteristics (traffic intensity, heavy transport, number of accidence, traffic congestions at crossings), § economic aspects (associated investments, payback period).
Condition of the undermined roads It is clear from the figure above that the undermining effects are quite extensive - they reduce operation safety, comfort and function.
It is, however, necessary to arrange that low costs will not influence the operation safety.
