To improve the security of EoC network traffic, the hybrid encryption scheme was presented.
As a result, this paper study the security mechanism of EOC system from the point of traffic data encryption and propose a method in which ECO downlink traffic is encrypted with hybrid encryption scheme combined with the special circumstances and security requirements of EOC system.
Commonly used AES can provide a good safety performance, but the resource occupancy is slightly large in the environment where the computing resource is limited.

Introduction With the popularity of the concept of sustainable development, it has been recognized that the road network construction target not only adapt to the traffic demand and improve the road network traffic performance, but rather to develop a concrete highway network planning.
Many index comprehensive evaluation index classification We refer to various kinds of comprehensive indexes classification methods of domestic and international to design a multi-level grading standard according to the normal distribution, and gibe the appropriate classification comments.
At the same time, when improving the technical grade and the level of science and technology of the road network we should take attention to the negative effects of highway traffic on social and environment development, and minimize the negative effects of road traffic as far as possible and promote the sustainable development of road traffic.

Introduction Crash safety of automobile has become one of the research focuses the last decade in the field of automotive passive safety research [1], especially the coach, which result in the casualties and property damage will be enormous in the event of traffic accidents for its large capacity and high usage.
Therefore, the body frame needs to be improved to increase its frontal crash safety.

ITS can effectively make use of existing transportation facilities, to reduce the traffic load and environmental pollution, to ensure traffic safety, improve transport efficiency [3].
Floating Car Data technology is one of the International Intelligent Transportation Systems (ITS) in recent years, advanced technical means of access to the roads traffic information.
The traffic flow is the basis data of the urban traffic guidance.

Introduction Advanced Driving Simulators (ADS), which coupled with high-fidelity scenario & audio subsystem, multi-DOFs motion subsystem, cab subsystem and multi-channel projection subsystem etc., have become the key experimental equipment in current traffic safety research area and played great role in the study of driving behavior, road safety audit and traffic crash reconstruction and so on.
Employing with ADS, the drivers were immersed in sight, sound and movement so real that impending traffic crash scenarios can be convincingly presented with no danger to subject drivers.
It provides the perceptual information of wheels and different road conditions for drivers and subsequently prompts drivers to take appropriate driving behavior (such as speed, steering and braking, etc.) to ensuring their traffic safety.

TT has also an important applicability in transport logistics - to reduce distribution costs for operators, distribution safety, improve service quality, efficiency establishing a network for planned transport: CVO (Commercial Vehicle Operation), EMS (Emergency Management System).
Numerous studies have shown that TT is a transport indicator sensitive to several factors: Demographic, Urban, Road design and management, road signalling system; The level of congestion of traffic flow; Human; The vehicle and its facilities; Environmental factors; Time of day, week, month, year, holidays, seasonality, tourism; Traffic flow characteristics coordinated with the signalling system; Special incidents that cause delays during trips; Speed traffic flow; Structure of traffic.
When travelling the test vehicle was driven in accordance to the general traffic flow.

First, the concentric circle structure about city traffic demands and traffic resources of cities.
Therefore, it brought a series problem, such as city traffic, traffic congestion, average speed is declining;,but the traffic accidents increase.
Solve the city traffic jam, the overall objectives and positioning of city public transportation is the completion of the "city public traffic system guarantee, service quality, perfect facilities, operation safety, management norms", the establishment of city public traffic status in the city traffic system, better satisfy people's basic demand for travel.
The fourth is the public traffic space to upgrade, various elements integrated rail, bus, slow traffic system and traffic environment, traffic environment, to create safe, efficient, green traffic space, improving people's travel quality.
