  Have learned nearly two years about the transportation, I confirmly understand the difficulity to be a  traffic engineering.They not only focus on the traffic itself,but also spicialize other field such as the optimal network theory,the linear algebra and the operation reasearch. Achieveing this subject needs much of effort and the continuous learning.Take the subject ot the traffic engineering for example,this field contains many cours that we have to study. First, we have to know about the definition of the  volume and to compute them according to the other effect that may lead to the make over .The consideration  must be conscientious and careful as the subtile design error may cause the whole network fail.Second,they should acquire the computation of the signal design.Where the signs have to be placed ,how do they set off that kind of traffic siganl and what time does the all phase and the green light can get. With the all thought ,they can conclud that wheather the approach should set the traffic signal and so on.I think that I have to strenghen the related field that improve my profession about the traffic.
