这些影响因素我们也有想到，可是要用模型函数把它们的影响，作用结合起来不易啊！

A classic summary of title
Combination of these practical, we have established a mathematical model to study the factors that affect the traffic flow in order to better assist us in designing the traffic around the island to solve some common problems, and put forward feasible contingency program. In the optimization of our model, considering the different markers set into the mouth method, changes in traffic flow and non-normal circumstances such as: accidents, road maintenance, weather and other factors, to fully explain our model is accurate, used in the design of traffic around the island is reasonable and feasible.

For different markers set into the mouth, we established a comparison model. Our model is the same loop by comparing the size of the delay time to realize I sign into the settings to determine the merits of Ways. Delay time refers to. . . . . . . May be set to a certain extent reduce speed signs and traffic lights can be set up to meet the flow loop size, we select a more economical method of energy conservation rather than simply to judge the traffic flow as the basis of size. We model a number of cities in the center of a loop simulation test, the result is in line with the facts, the same time, we also analyzed the impact of delay factors are: the flow of the paragraph loop size, loop length and radius, the number of crossroads, how many lights, as well as the impact of weather conditions.

Through our model the result is that traffic flow is small, reduce speed signs Ways to meet the requirements, preference will select it. When traffic flow is large enough, we must consider traffic lights to manage traffic control. Signal to be used in the circumstances, stay green during the day and 30s, the night of 20s, rain and other inclement weather when the 40s. When the loop appeared in the above-mentioned non-normal circumstances, they make a simple analysis and testing, and put forward relevant proposals and contingency measures.
