In order to explain NO<SUB>2</SUB> pollution mechanism in the envions of main traffic roads, NO<SUB>2</SUB> concentration inthe period from year-end through beginning of next year was measured with TEA capsule.<BR>The following three results were found out.<BR>Firstly, the relations between NO<SUB>2</SUB> concentrations in the edges of R-43 (Route-No.43) and R-2 (Route-No.2) roads, and the number of passing cars through there could not be found to be linear.<BR>Secondly, however the difference between the relation in the period from year-end through the six daysin the beginning of next year, and the relation in the periods except the above period could be found to bepositive.<BR>Thirdly, NO<SUB>2</SUB> concentrations in edges of R-43 road were found to relate with the wind-direction andvelocity.
