======= Review 1 =======

1.The detection principle of the WARIM is not clear,so
describe the detection principle  before the experiment,for
example ,how to detect the vehicle by PRR.

2.In the experiment 1, at d=8m,add comparative data of
multiple measurements between B to A and A
toB,which to be sure the reasons of the different
PRR.

3.Under the experimental test scenario, increase external
electromagnetic interference quantitative description.

4.The phrase is not accurate enough to express some
sentence,Please re-examination of the full paper. 



======= Review 2 =======

This paper proposed a WSN architecture for intersection
traffic monitoring based on experimental results. 

However, the experimental results show that 5-10m is chosen
to be the distance between two sensors on a given lane
without theoretical analysis . Short distance leads to
better connectivity, but meantime it is needed to deploy
more sensors which will result in more financial cost.
