True. The traffic system brings needed order and organization to driving.

Explanation:

To understand this answer we need to remember the concept and then apply it to our context. The concept of traffic makes references to the flux of vehicles that circulate over a certain urban system. the word traffic is misused by the common person because it is taken as if it meant an accumulation of traffic in a certain area without an efficient circulation. Thus, we have a misconception about it and that is why we associate the word to another meaning. Nevertheless, the traffic system is the planning of a certain urban street net to guarantee communication over a certain settlement.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.
