In the past, concrete linings were built in Korea with scanty attention to their fire safety, as demonstrated by the lack of studies on fire resistance of both materials and structures.
Introduction Long 40~60 m deep underground tunnels are being planned to be constructed in Korea to solve the problem of serious traffic congestion which has been caused by the rapid growth of cities.
In Korea, active fire protection centering on saving lives has been the mainstream in the safety design for tunnels against a fire.
Difficulties in reparing, as well as safety issue are inherent in tunnel fires.
Fire-resistance evaluation standard for tunnel structures provided by the ITA(International Tunneling Association) suggesting maximum concrete temperature of 380°C was used in the test.

Introduction Machines, traffic and blasting generate surface waves that can adversely affect nearby structures.

The Adaptive Front-lighting System (AFS) has been widely concerned in the area of traffic safety.
Therefore, preview control model established has good control effect, and can improve the system’s active safety.
The preview control system built has good effect which can increase AFS system’s active safety.

In March 2012, the official website for eVolo – the American architectural journal - posted its listing of those architects awarded top tier in their annual Skyscraper Competition.
As international diplomacy between east and west has developed, over the last twenty years, Chinese architects have become more and more internationally renowned for their ingenuity.
The project conceived of attaching double skinned skyscraper to the mountains so as to not only restore the ecological environment but also help the indigenous community get between work and home, safety and promptly.
They predicted that due to the development of intense traffic, caused by the overburdened public transport system and heavy resource consumption, a large number of vehicles will be abandoned by the city’s residents.
Their triumph demonstrates the benefits of international collaboration and has made Chinese conceptual architecture the model for the world to beat.

Each application field contains several main aspects, for example, transport organization contains dispatching, transport organization, train operation control and traffic safety monitoring.
Analysis on signal industry chain of rail transportation The function of the railway signal system is to ensure traffic safety, improve interval and the carrying capacity of station and the classification ability of marshaling station through collecting, analysing and processing the information of railway transportation.

The current city land use pattern in Taiwan is still in the city mode based on traffic way development.
Green Transportation Since the 1950s, the land use pattern based on private operation in major cities in the world has caused many problems in the inner structure and outer environment of the cities, such as urban sprawl, environment pollution, financial difficulty, economic depression, insurance expenses, traffic jam, transportation cost, personnel safety, health, and interpersonal alienation, etc,.
It also takes problems such as traffic jams along with the development of the cities, and living environment quality debasement, etc,.

Introduction Along with the increasing traffic volume, traveling speed and axle loads, serious premature failures occurred on many asphalt pavements soon after opening to the traffic, such as flooding oil, loose inside, frost boiling, settlement and bottom stripping [1].
Because of the dynamic load of traffic and temperature expansion and contraction repeated affect, the water which enter the asphalt pavement voids continuously generate hydrodynamic pressure or the vacuum cycle, water gradually infiltrated into the interface of asphalt and aggregate, then the asphalt will be emulsified, the strength of asphalt mixture will be declined [5].
That is seriously reducing the use of pavement performance, endangering the traffic safety, shortening the life of asphalt pavement, and causing enormous economic losses.

When fault is detected, alarm message will be sent to the monitoring center of the system to ensure the safety of the following vehicles.
Track dynamic examination is an important method to ensure traffic safety.
It detects the vibration caused by interaction of train wheel and railway track and computes the real-time data to monitor the track condition to ensure safety.
u The wireless transmission module will send alarm message to the monitoring center of the system and the following trains may decelerate on the region of fault track for safety.

Its dynamics quantitative and qualitative determininations are made comparing the fake traffic situations with the real ones.
The driver is able to adapt to different traffic situations, when the vechicle orientation changings are necessary on trajectory.
