"Use-Case related evaluated distance estimation technologies"

Date: Jul 2016

Pages: 104


This deliverable, entitled “D4.1 Use-Case related evaluated distance estimation technologies”, contains the fundamental description of the C-ITS distance-estimation framework after the first year of activities of HIGHTS project. It comes along other three relevant deliverable: “D2.2 Geolocation Referencing Sub-System draft” which describes the main architectural aspects of the ITS system; “D3.1 Protocols & Facilities (Cooperative Communications) [Early]”, taking care of the communication aspects; “D5.1 Cooperative Localization Algorithms and Hybrid Data Fusion Schemes [Early]”, describing the core of the Geolocation sub-system.

In turn, the main objective of D4.1 is to focus on the distance-estimation technologies that can be employed within the C-ITS context. The analysis starts from the raw technological description and moves toward the contextualization with respect different road use-cases and scenarios. A single technology cannot be evaluated per se but rather needs to be applied to some specific case. Since we are discussing enablers for potentially lifesaver applications, it is important to provide practical description of pros and cons of each technology. For this reason D4.1 lists all the relevant use-cases and scenarios as depicted in D2.1 and extract, for each of them, the main requirements. Only as second step this document investigates which out of, and weather, the considered technologies could be employed in that particular case.

Since D4.1, as already stated, shall be read in a wider context with the other 3 aforementioned deliverable, it defines also the relevant interfaces toward the rest of the ITS architecture.

Finally, concluding and summarizing the outcome of the first year of HIGHTS, the current document provides a first selection of algorithms and technologies to be later validated (during the second year of the project) and implemented and integrated (year 3 of HIGHTS).



"Definitions of the cooperative ranging sub-system"

Date: Jul 2017

Pages: 49


Scope of this deliverable is to document the status of the current work in progress regarding the HIGHTS ranging sub-system (RSS) and its evolution to the HIGHTS cooperative ranging sub-system (CRSS).

The HIGHTS RSS is one of the core sub-systems within the HIGHTS project to achieve the overall high accuracy goal. Next to the strong connection to the communication sub-system on the one hand and the interactions with the localization sub-system on the other hand it finally provides distance estimations of different technologies to the upper HIGHTS components.

There are not only radio based ranges which will be handled by the ranging sub-system, it is also prepared to use ranging from technologies which will generate distances in an intermediate post processing step like laser scanners do. The very flexible RSS architecture is embedded within the HIGHTS ecosystem to fulfil all requirements for a seamless cooperation within the HIGHTS components (timing sub-system, storage sub-system, etc.). In the current development progress the RSS is capable of getting ranging from several radio based distance estimation technologies and there is a preparation for technologies which provide values which need additional processing.

The overall architecture of the RSS is designed to fulfil all requirements for the CRSS. The CRSS is able of combining different outputs from the RSS to an input stream for the higher level HIGHTS cooperative sub-systems.
