Evaluation of Influence Factors in Diesel Truck Pollution Control

Abstract

Diesel truck pollution emissions are major air polluting sources. Pollution control of diesel trucks is one of the important measures to improve air management. In order to study the influence factors in diesel trucks pollution control, an evaluation system consisting of one target layer, three criterion layers and 15 indicator layers was constructed. Through the comprehensive evaluation software Super Decision, the consistency test is passed, and the weight values of each indicator are obtained. Results show that the most important factor that affects the degree of diesel truck pollution is the number of law enforcement officers, with a weight of 0.24. The sum of weights of number of law enforcement officers, popularizing rate of environmental knowledge, blacklist rate, diesel trucks inspection rate, pollution control device configuration rate, correct use rate of pollution control devices, diesel truck emission standards is up to 0.84, which indicates that the seven influence factors determine diesel truck pollution control. The conclusions provide references in formulating measures to diesel truck.
