Because of its fast running, elevators, with great potential value and social requirements, are now days becoming very important traffic tools in high-rise buildings.
“The international symposium on elevator evacuation during high-rise building fire” was hold successfully in Shanghai in 2007.
The air curtain can ensure the safety of the elevator evacuation.
Only in this way, we can make sure that elevators undertaking the task of daily vertical traffic must become a kind of effective vertical evacuation way.

The five indicators were Speed, Gradient, Radius of Curvature, IRI, Traffic Volume and Green Belt.
Considering the requirements of different levels toward traffic safety, economical efficiency and environmental impact, block out equivalent green belt width data, and written in table 1.

It is expected that CACC will increase vehicle traffic efficiency and traffic stability [8].
As the ACC systems become increasingly complex, the development of the technologies largely via field test under real-world environment have become more and more impractical, if not impossible, mainly due to the cost, time spent and safety.
The virtual environment represents the outside world and takes into accounts of traffic environment (traffic flow, traffic signs, etc.), road environment (road boundary, speed limit, lane numbers, etc.), and weather conditions (sunny, rainy, windy, etc.).

Introduction According to the safety evaluation system of coal-fired power plant, we can control various factors which affect the safety of coal-fired power plant through comprehensive analysis to production safety, labor safety and equipment safety.
Construct Comprehensive Security Evaluation Model Construct index system According to the safety evaluation system of coal-fired power plant, we can control various factors which affect the safety of coal-fired power plant through comprehensive analysis to production safety, labor safety and equipment safety.
The evaluation index system and sore is shown as below: Table 1 The evaluation index system and sore One class index Secondary indexes Score A B C D E Production safety （0.3） Responsibility of production safety 8 6 5 7 9 Safety supervision system 7 9 6 7 8 Rewards and punishments of safety 7 8 9 9 7 MBO of safety 6 7 7 8 9 Comprehensive management 9 7 8 6 5 Equipment safety （0.3） Boiler and steam turbine equipment 8 9 7 9 8 Electrical equipment 7 8 6 8 9 Thermal and chemical equipment 9 8 6 7 8 Storage facilities of coal and oil 7 8 8 9 7 Desulfurization 8 6 7 9 6 Other facilities 8 6 7 7 9 Labor safety （0.4） Traffic safety 8 7 7 6 9 Working environment 6 9 8 7 7 Safety of fire and explosion 5 6 9 7 8 Flood control 7 7 9 8 6 Earthquake control 9 8 7 9 5 Determining the weight by entropy weight method (1) Production safety According to the safety evaluation index system and scoring condition, we can get the initial matrix: The Weight vector is: (2) Equipment safety The Weight
vector is: (3) Labor safety The Weight vector is: Fuzzy comprehensive evaluation (1) Production safety The results obtained is comprehensive sore of production safety, we can see that 4 experts are satisfied with the production safety except 1 expert

Once cable lines beak off, the system underground will be paralyzed, which will affect the production safety and the rescue work.
Then the sum of data traffic of nodes in is,
If we want to balance data traffic among each layers, we need to let variance of data traffic in each layer be the minimum, that is to say, searching to make the variance of minimum, is,
