Gap Analysis in Cooperative Systems within Intelligent Transportation Systems.

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.
