Argument4 Forestville Speed LimitSix months ago the region of Forestville increased the speed limit for vehicles traveling on the region's highways by ten miles per hour. Since that change took effect, the number of automobile accidents in that region has increased by 15 percent. But the speed limit in Elmsford, a region neighboring Forestville, remained unchanged, and automobile accidents declined slightly during the same six-month period. Therefore, if the citizens of Forestville want to reduce the number of automobile accidents on the region's highways, they should campaign to reduce Forestville's speed limit to what it was before the increase.
Conclusion: Forstville should reduce the speed limit to what it was before the increase, if the citizens of Forestville want to reduce the number of automobile accidents on the region’s highways.
1. 提速导致交通事故增多没有直接的因果关系,就像作者提到的Elmsford的限速没有变,交通事故却减少了。
2. 假使提高限速会对交通事故有影响,但是否还有其他的因素导致交通事故增加。(如新手增多,不遵守交通的人增加,而Elmsford,使用交通工具的人减少等)
3. 设想速度对Elmsford的交通事故率有影响,在Forestville是否会产生同样的效果。因为两地区的人口数,司机的水平,路矿也许不一样。
The speaker claims that increasing the speed limit induces to the increasing number of automobile accidents during the last six months, so only through reducing the speed limit to its original level can change the situation.
First, there is no direct cause and effect between speed limit and the number of automobiles accidents considering it is highways which no people walk on it. Moreover, just like the speaker selves said, speed limit in Elmsford remained unchanged, and automobile accidents declined slightly. If increasing speed limit increases the number of accidents, equally, keeping the speed limit should make the number of accidents unchanged.
Therefore, the speaker asserted the effect of speed limit without considering any other factor. For instance, the number of green hands may become rising during the six months, large number of people traveled to this region but cannot follow the traffic rules and induce to the traffic accidents, and drivers may become less careful when following the new traffic criterion. However, the situation of Elmsford may be contary, people were likely to stay home and not usually used the traffic transportation during the same time.
Providing that speed limit has effect in the Elmsford, it can not assert that reducing the speed limit to what it was before will do work in Forestville. Considering the elements of topographic, population, and the level of drivers. Furthermore, why Forestville need reduce the speed to the original speed limit, these is no evidence confirms that original speed limit is the best and most safety one.
Meanwhile, the number of automobile accidents in Forestville has increased by 15 percent which the speaker gives us is very skeptical. Because we can not understand whether the statistic is calculated by scientific method. We should figure out when he or she compared these numbers whether took into consideration the changing number of drivers. If the accidents happened more accompany with the increasing number of drivers, while the increasing rate of accidents less than of drivers, actually, the situation of traffic improved.
To sum up, even if Forestville reduces its speed limit to what it was before the increase, it may have little effect on the reduction of the number of automobile accidents considering the increasing number of green hander or some other changing elements, even the bad weather.
