Research On The Five Dimensional Quantitative Evaluation Method Of Driving Active Service Quality Under The Vehicle Networking Environment

With the rapid development of economy and the continuous innovation of science and technology,the Driving Active Service System?DASS?has been widely used with the help of vehicle networking technology.With the wide application of DASS technology,the requirement of DASS service for traffic users is increasing day by day.In order to improve the quality of DASS service and the ability of DASS services,it is necessary to evaluate and judge the quality of DASS service by using the feasible method,so as to provide more efficient,safe and environmental services.However,there is little literature on DASS service quality evaluation,which requires us to learn from the merits of the common evaluation methods.At present,according to the different objective problems,the evaluation methods are not the same,the overall can be divided into two categories:subjective and objective weighting evaluation method.Based on the analysis of the advantages of various evaluation methods and the combination of the characteristics of DASS system,using the integration of DASS service robustness,autonomy,adaptability,scalability and real-time characteristics,five quantitative evaluation method and technology system structure,according to the DASS service quality comprehensive evaluation,improve the DASS service improve the service quality,diversification,and meet the different needs of the user's traffic.At the same time,it makes up for the blank of the evaluation of service quality,which is of great significance for the realization of the multi level and all-round evolution law of DASS.This paper mainly does the following three aspects of work:?1?The characteristics of DASS services are analyzed in detail,and according to its characteristics,a five dimensional comprehensive evaluation index,namely robustness,autonomy,adaptability,expansibility and real-time is put forward,and a perfect evaluation system is set up;?2?According to the advantages and disadvantages of the common subjective and objective evaluation methods,a five dimensional quantitative evaluation model of DASS service quality is constructed by combining subjective and objective methods.The minimum value f_{cos t}is used to represent the optimal service;?3?Build PreScan simulation scene independently,select two typical scenes as simulation scenes in the 86 types of application scenarios.The simulation results verify the feasibility and effectiveness of the five dimensional quantitative evaluation algorithm,and can effectively evaluate the quality of DASS services...
