Smart concrete can also be used to monitor building occupancy for intruders or for people remaining during the evacuation, and to monitor traffic flow in an emergency. 2.
In case of a large building, such data obtained from sensor network shall enhance the safety of occupants and well as firefighting crews. 3.

The block diagram of sensor detection system in automobile whole process Cases empirical analysis According to the latest statistics, automobile rear-end collision accident is the main road traffic.
It uses radar anti-collision device in automobile body, and detects safety distance.
When it is over the safety distance, it alarms, so as to effectively reduce the rate of accident.

Palomoa had presented a novel approach to analyzing and visualising network traffic data based on growing hierarchical self-organising maps (GHSOM), the GHSOM was used to cluster network traffic data and to represent this in a manner [3].
After the new crime behavior being discovered, forensics is in the active state, the safety system reconstructs the crime behavior integrally, and makes evidence integrity and legal efficiency.

As shown in Fig.1: interior space tends to have more frequent activities will be used as a hub to organize part of space in order to reduce the length of traffic and at the same time save space.
Efficient use of traffic space In the design of public space, the effective and reasonable reduction in traffic area can reduce the public sharing area and improve the ratio of using space of the unit[3].
Therefore, enhance the identification of neighborhood space, construct appropriate living facilities and enhance the public safety management will increase people's sense of belonging.

When the temperature is frequently changed between warm and cold, the snow and ice on the pavement surface will melt under the traffic loads.
As the stability and safety of the vehicles operation is vitally affected, the rate of the traffic accident will be significantly increased.
Therefore, to explore a proper way to guarantee safe driving on the snow and ice road, avoid or reduce traffic accident, improve road passing capacity, and boost the road winter management efficiency has become an essential subject to the road management department.
