Abstract：Research purposes:Road traffic signs and markings are important parts in the Traffic safety facilities，they are the most effective way of guiding vehicle along the way，which also can significantly reduce traffic accidents and improve transport efficiency．In this paper，introduced some basic design principles，concepts and materials in french traffic engineering，which can be useful to China＇s highway designer and be helpful to develop overseas highway project．
Research conclusions:(1) For the purpose of facilitating regional Traffic and improving road safety，France joined the" Convention on Road Traffic"and " Convention on Road Signs and Signals" which were formulated by United Nations ．(2) Traffic system in Africa road usually adopted the Europe standards．(3) There are some differences between homeland and oversea in traffic engineering system，but it is gradually in line with oversea’s．(4) The construction machine and materials of traffic markings are developed more slowly in our country，there is disparity with the developed countries，and we should accelerate the development step in research area．
