According to the statistics of the ministry of public security traffic management bureau, a lot of traffic accidents are related to vehicle bumper, which, as one of the main bearing and energy absorbing parts in traffic accidents, mainly serves to protect vehicle components and occupants.
Bumper beam system[7] means much importance in vehicle safety, absorbs collision energy through deformable energy-absorbing device, converts and balances collision energy through bumper front beam, and via front rails converts high-speed collision energy to column A,roof rails and doorsills and so on.

The smoothness of railway tracks diminished, and the speed of passing trains had to be limited to ensure safety.
As a result, the traffic can be resumed in time after the uplifting of concrete structure
The maximum settlement deformation was 50 mm and the maximum elevation difference between adjacent roadbed slabs was nearly 30 mm, which had seriously affected the traffic safety.
Conclusions The polymer grouting uplifting rehabilitation technology for ballastless track in tunnel has the advantages of rapid restoration and good effects which can neither affect the track structure stress adversely nor affect the traffic safety.

Introduction With the explosion of private cars, traffic accidents are more frequent.
In this case, it is likely to cause a traffic accident and is responsible for it.
This data collection strategy stated above has chosen to record only the representative vehicle operation parameters which may pose a threat to the traffic safety.

However, it also has an important role in securing track stability in all directions, and thus to be in accordance with permanent track maintenace work due to the defects caused by traffic density and other external effects.
The three basic parameters to identify the most applicable railway track are the economy, safety and comfort.
In terms of safety conditions near the track, the vehicles and the traffic system also have an important role.
It can be conluded that many economical, safety and environmental conditions have to be taken into account at the selection of the superstructure type.

Because of the characteristics, monorail traffic is becoming one of the preferred type of mountainous city, small city and waterfront urban rail transport.
In the single-track vehicle operation, excessive wear of tires will affect the acceleration and deceleration and braking performance of monorail, endangering traffic safety.

In order to adapt to complex and diversified international environment and the requirement of military struggle preparation, China planned and built some highway-runway corresponding to related expressway (grade) highway in mainland in combination with building of highway net, hereinafter it is briefly called highway-runway.
The loosened grain material on the asphalt pavement shall impact the safety of driving during transit of automobile.
Furthermore, the additional vibration effect shall also worsen the wearing of airplane parts, and endanger safety of flight.
In general situation, the automobile passes through the grade class day and night, the traffic volume is usually heavy, the channeling phenomenon of asphalt pavement is serious, and usually incur track pit on the traffic lane.
