Car Navigation And Travelling Data Recorder System Performance Evaluation Methods

With the increasing of integration for the car navigation and travelling datarecorder system, there are increasingly problems of performance and stability appeared,and the performance indicators and the quality results of rapid determination systemare becoming increasingly difficult. Therefore, this research project will provide anevaluating method for the performance indicators of the car navigation and travellingdata recorder system. Through establishing the performance system of car navigationand travelling data recorder system, design the system of evaluation test method andevaluation process, and using the visual way to analysis the quality of the system undertest. Thus could solve the problem of evaluating the car navigation and travelling datarecorder system effectively and rapidly.The performance indicators design of the car navigation and travelling datarecorder, basic on system architecture and feature classification, to display theefficiency and rationality of the spatial navigation data system, the accuracy andtimeliness of the spatial data travelling data recorder, and the efficiency and rationalityof the route planning, for designing an indicator system of performanceevaluation.Combine with the industrial standard of vehicle navigation and travellingdata recorder, providing the indicator threshold of performance evaluation for eachpart.To determine the test method of performance indicator for navigation travellingdata recorder, it needs basic on the features under test system, through the approach ofequivalence class analysis, design the system performance evaluation case collectionwhich satisfy the coverage rate requirement with representativeness. Basic on thesituation that huge spatial and spatio-temporal data is difficult to visual analysis,design a visualization analysis method for space navigation evaluation results,spatio-temporal running record data analysis and navigation route planning results.Through establish the evaluation system and the performance indicators of carnavigation and travelling data recorder system, design and develop the automatedsystem performance evaluation tools, realization of the automated evaluation processfor space displaying data, spatio-temporal travelling data recorder’s data, and navigation route planning results under test. To visualize the results, satisfy therequirement of rapid regression verification and visual result analysis under test.This research project could evaluate the degree that performance indicatorsreached under test through establish an evaluation method of performance for the carnavigation and travelling data recorder system. A large number of experiments showthat providing the performance indicators and the performance evaluation methodscould confirm the performance indicators of car navigation and travelling data recordersystem, and providing the evidences for rapid completion of evaluation, system’sperformance and reliable optimizing.
