各位英语强人，帮我把下面一段汉语，翻译成英语吧，急用，多谢了。
With the scientific and technological progress and national economic development, electricity transmission networks grades improved, people generally enhance the awareness of energy conservation. China's industrial and mining enterprises supply voltage levels for most of 10 kV, and 6 kV high-voltage motors to the majority, therefore enterprises need for the establishment of such electrical power transformer. Power Transformer access is not only complicated system, maintaining a large quantity, but also its own power transformer losses. This paper will be aimed at analysis of 6 KV three-phase asynchronous motor transformation for the same three-phase capacity of 10 KV electric induction, simplified system to achieve energy-saving purposes.
请英语高手帮忙翻译一段文章，文章有点长，小弟表示歉意，不要用翻译器翻译的，非常感谢！
Traffic Volume
【交通量】
The role of the traffic engineer is to enable all traffic to travel on the road at a reasonable speed and with an appropriate degree of safety. This is not the loading that is used in the Pavement Design. These values are used to determine the road width only.
【交通工程师的职责是让整个交通以在合适的安全度下以合理的速度在道路上运行。这样的一个“承载量”并非我们在铺路设计中所应用的那个“承载力”，这些数值仅仅是用来确定路面宽度。】
With relation to the volume of traffic using the road, the passenger car is adopted as the standard unit and other vehicles are assessed in terms of passenger car units (pcu).
【与道路使用的交通流量有关，客运车被当作标准参照，其他车辆则以“客运车单位(pcu)”来进行描述。】
Differences in the urban and rural situations arise due to the variation of speeds in the two areas. Decisions on road width are not normally made on total traffic flow per day as this is misleading but rather on the peak hourly flow. In Britain the maximum permissible flow is 3,000 pcu/h for a two lane dual carriageway and 4,500 pcu/h for a three lane dual carriageway (motorway). For all purpose roads with junctions these figures reduce to 1,100 ‘‘and 1,900 pcu/h respectively.
【城市与农村两个区域运输速度的不同导致了他们状况的差异。道路宽度的确定并非由通常每天的总流量来确定，因为这在运输高峰期时完全就是一种误导。在英国，二车道通行的双向车道最大通行量是3000客车单位/小时，而三车道通行的双向车道(高速公路)则是4500客车单位/小时。而在那些带有路口的路上，这两项数据分别减少为1100客车单位/小时和1900客车单位/小时。】
Where the road is new, studies must be carried out to estimate the volume of traffic expected to use the road. Where the new road replaces existing roads this is not too difficult. If however the road is expected to change the flow of traffic then analysis should be carried out as to the volume and constitution of traffic on the new road. Matters are further complicated if the road is very long or provides access to or from a large town. Computer methods are now available to aid in this process. The constitution of traffic on the new road is of interest to the pavement engineer.
【当道路新造成的时候，为了预计道路的使用情况，就必须通过进行研究对交通量进行估计。如果新道路是用来替代旧道路，那么这项工作并非很困难的事情。然而，如果新道路的预期是要改变交通流量，那么应该就新路交通流量和交通结构进行分析。如果道路非常长，或者道路是通往大的城镇，那么分析工作还会变得更加复杂。现在计算机方法已经被应用到这种分析过程中，新道路的建设是路面工程师所关注的。】
Traffic Loading
【交通负载】
In this section, we will discuss the traffic loading that is taken forward to the pavement design section. Unlike in the above section where Passenger Car Units were the reference unit, we will work in Standard Axles. This is a reference unit to determine the average loading on a pavement by what is known as the standard axle. This then allows a total loading over the life of the pavement to be determined, normally in Millions of Standard Axles (msa).
【在本章节，我们将会讨论交通负载 路面设计部分。这里并不想前面章节那样用“客车单位”来作为参考单位，我们使用“标准车轴(Standard Axles)”来计算。“标准车轴”是一个用于确定路面平均负载的参考单位。这个参数一确定，路面在整个工作寿命期间的总负载也随之确定，计数单位通常使用“百万标准车轴(msa)”。】
1 pcu/h=1 客车单位/小时
