Abstract
This study proposes trusted measurement and evaluation models for intelligent transportation system products to provide technological means for the transport sector and government departments to detect the compliance and availability of intelligent transportation system products and consider the market access of intelligent transportation system products. Then, this study builds a trusted testing platform based on a hardware-in-loop system to test and validate trusted measurement and evaluation models of intelligent transportation system products. Finally, a traffic signal controller is tested and validated in the platform in different operation environments. The result shows that the trusted measurement model can accurately measure the trusted status in normal and non-normal operation conditions, and the trusted evaluation model can dynamically calculate the intelligent transportation system product’s trusted attributes, namely, the trusted evaluation values and comprehensive trusted evaluation values of the intelligent transportation system product, as the intelligent transportation system product’s operation environment changes.
Highlights
Intelligent transportation systems (ITSs) show positive effects on improving traffic operation efficiency, alleviating traffic congestion, ensuring traffic safety, and reducing traffic emissions, among others
With the application and popularization of ITS in the area of transportation, especially in urban traffic system, people are becoming increasingly dependent on ITS products
In China, there are more than 2000 corporations engaged in the ITS industry.[2]. The products of these corporations include hardware products, software products, and integrated systems. These products are used in the fields of traffic signal control, traffic flow guidance, traffic information service, electronic toll collection (ETC) system, traffic monitoring, and so on
Summary
Intelligent transportation systems (ITSs) show positive effects on improving traffic operation efficiency, alleviating traffic congestion, ensuring traffic safety, and reducing traffic emissions, among others. In China, there are more than 2000 corporations engaged in the ITS industry.[2] The products of these corporations include hardware products, software products, and integrated systems These products are used in the fields of traffic signal control, traffic flow guidance, traffic information service, electronic toll collection (ETC) system, traffic monitoring, and so on. These products’ reliability, usability, testability, maintainability, and security are of varying quality. In section ‘‘Discussion and conclusion,’’ a brief review of this article and the future research are presented
