Real-time locating systems for smart city and intelligent transportation applications

摘要

In this paper, we focus on practical issues related to the implementation of real time locating systems (RTLS) in the context of vehicle-to-infrastructure (V2I) communication. These emerging concepts are an important part of novel areas such as Smart Cities and Intelligent Transportation Systems (ITS). Some problems encountered during the development of these systems result from the limitations of technologies that are supposed to become the basis for these new applications. In our opinion, there is additionally a direct link between the development of the new technologies, the architectural planning, as well as regulations. An appropriate planning of surrounding of the road will facilitate the realization of V2I systems. On the other hand, technology limitations will provide guidance how to design the road environment. In this work, we focus, in particular, on the assessment of the localization precision of RTLS used in ITS. The precision to some extent will depend on the variation of physical parameters of the used circuits, e.g. PVT (process, voltage, temperature) variation → delay in answer → localization error → safety issues.
