Abstract [en]

This master thesis project was performed at Volvo Group Trucks Technology (GTT), Advanced Technology & Re- search within the department for Intelligent Transportation Systems, located in Gothenburg, Sweden.

This thesis provides an gap analysis in an area called cooperative intelligent transportation systems, with a particular focus on wireless-based solutions for vulnerable road users such as pedestrians and cyclists. The aim of the analysis is to investigate the current status of the area and compare that to what is wanted in future. Naturally, by us- ing smartphones these vulnerable road users should be able to be part of a wireless cooperative solution. It was showed that there exists a need for wireless-based cooperative solutions and that a technical obstacle is present, namely in- compatible communication protocols between smartphones and vehicles.

The analysis led to a hypothesis for how to solve this problem and was implemented as a proof-of-concept. IEEE 802.11a/b/g was used to communicate between smartphones and road side units (a device integrated in traffic infrastructure), to further relay that communication from the road side unit to vehicles by using the vehicular standard protocol IEEE 802.11p. This concept created a bridge over the obstacle and it was shown that the proof-of-concept worked well without any significant delay.

Abstract [sv]

Det bakomliggande projektet till denna rapport utfördes vid Volvo Group Trucks Technology (GTT), Advanced Technology & Research, på avdelningen för Intelligenta trans- portsystem, i Göteborg.

Denna rapport tillhandahåller en gap analys inom om- rådet kooperativa intelligenta transportsystem (eng. coope- rative intelligent transportation systems), med särskilt fo- kus på trådlösa lösningar för oskyddade trafikanter (eng. vulnerable road users), dvs. fotgängare och cyklister i hu- vudsak. Målet med analysen var att undersöka områdets nuvarande status och jämföra med vad som önskas i fram- tiden. Att använda smartphones för att integrera fotgäng- are och cyklister i en kooperativ lösning med fordon var en naturlig utgångspunkt. Det påvisades att det existerar ett behov av trådlösa lösningar i fordonssammanhang och att det finns ett tekniskt hinder gällande inkompatibla kom- munikationsprotokoll mellan smartphones och fordon.

Analysen ledde till en hypotes om hur detta hinder kan överbryggas och detta realiserades i ett proof-of-concept. Protokollen IEEE 802.11a/b/g användes mellan smartpho- nes och trafikvägsenheter (eng. road side units) (typiska trafikenheter i traffikinfrastrukturen), för att sedan vida- rebefordra kommunikationen till omkringliggande fordon med hjälp av det fordonsspecifika kommunikationsproto- kollet IEEE 802.11p. Lösningen implementerades och det visades att prototypen gav tillfredsställande resultat.
