The research of mechanized vehicle traffic resources condition is important to realize the development of environment and transportation system in harmony. This paper, from the view of static, dynamic and environment, sets up the evaluated index system of mechanized vehicle traffic resources condition, and construct a matter-element evaluation model on mechanized vehicle traffic resources condition by means of extensible engineering method. The grade of mechanized vehicle traffic resources condition and evaluated index as thing yuan, draw its land of classical land, festival, right coefficient. Dependence function is established based on the grade of mechanized vehicle traffic resources condition and then the grade is judged by calculating the synthetic dependence degree. ne example shows that this method is efficiency and in reason.
