Introduction This paper focuses on how to build this traffic cloud with the collecting and sharing traffic information.
The information could constantly reflect the vehicle status, vehicle location, vehicle safety and vehicle identification.
And for traffic managers, the traffic cloud platform can organically resolve problems in traffic safety, traffic environment and traffic flow in one platform and it greatly improve the utilization efficiency of information, saving information facilities for additional capital.

One important way to increase transport efficiency, reduce traffic congestion and improve traffic safety situation, is to implement traffic guidance and control, effectively use the road resource and give full play to vehicle function.

It is of great significant for improving traffic safety; easing traffic congestion and energy conservation in the future.
So it is essential to know the driver's characteristics effectively for future research issues such as real-time traffic safety warning.
The model was important for the microscopic traffic simulation model; it provided a theoretical basis for the real-time traffic safety warning system in the future.

And we must stress on tradeoffs between traffic flow and safety, the role of under- or over-posted speed limits, and other factors that may not be explicitly called out in this problem statement.
The scale factor of a, b, c is 0.5,0.3,0.2.Then we can get “Safety Factor” in the light or heavy traffic.
·Define a new concept“Safety Factor”to analyze the safety issues, quantify the abstract problem and make the calculation clearly.

The deficiency of parking place especially in town centers causes a lot of conflicts which influence the traffic flow continuity and traffic safety.
Proposal for Increase of Traffic Safety The following measures were taken as the basic points for increase of traffic safety on monitored section of the road: - the measures for simplification of parking maneuvers (if it’s possible), - the measures for reduction of speed.
