Due to the shortage of geographical information suitable for the visually impaired, the current navigation systems fail to provide high quality performance. The results of an international survey on the user needs are discussed in this article. A collaborative accessibility approach (COACH) is proposed to not only extend accessible geo-information, but also offer an opportunity to share experiences among peers. Related topics are addressed, like map data, multimodal annotation, and privacy.

I rapporten har vi förklarat vilka problem som kan uppstå med dagens teknik och vilka eventuella lösningar som man kan förbättra med tiden. Med hjälp av Trafikverket har vi genomfört detta examensarbete. Vi hade fått tydliga direktiv från Trafikverket gällande examensarbetets syfte. Det gjorde det enkelt för oss att avgränsa arbetet efter de riktlinjer som var angivna och möjliga att genomföra. Studiens syfte var att förstå varför det inte går ge ut relevant trafikinformation. I dagsläget har man tekniken för ett väl fungerande system. Ett system där man enkelt kan få realtidsinformation i samband med trafiken, vägarbeten och eventuella hinder. I rapporten har vi även sammanfattat alla navigationssystem som man kan ha användning av som trafikant. Vi har gjort en omvärldsanalys på hur man i andra länder ger ut trafikinformation och hur de står sig jämtemot Sveriges trafikinformationssystem. För vårt examensarbete har vi använt oss av diverse olika rapporter och intervjuer. Detta tillsammans med personer som har kunskap inom området. Vi har även använt oss av åtskilliga hemsidor för att inhämta information. Rekommendationer för examensarbetet kommer att beskrivas genom fem teman. I rapporten har vi utfört en mängd olika intervjuer som vi sammanställt till teman. Teman var utformade efter det vi kände var mest relevant från intervjuerna. Våra teman speglar bilden av vad vi har lagt vikt med detta examensarbete. / In this report, we have explained the problems that may occur with today's technology and what possible solutions to improve with time. With the help of the Swedish Transport Administration, we have implemented this thesis. We got the clear directions from the Swedish Transport Administration regarding purpose of this thesis. This made it easy for us to delineate our work after the guideline that was definer. The study's purpose was to try to understand why you can´t give out the relevant traffic information. Today we have the technology create a well smooth operation system. A system where you can easily get real-time information related to traffic, road works and obstructions. In this report we have summarized all the navigation system that you could use as a road user. We have done an analysis of how other countries give out their traffic information and how good they are against the Swedish traffic information system. For our thesis we have used various of different reports and interviews. The interviews have been with people who have knowledge in the field. We have also used numerous websites to gather information. Recommendations for the thesis will be described through five themes. In this report, we have conducted a variety of interviews that we have compiled for themes. Themes were designed for what we felt was most relevant from the interviews. Our themes are a mirror image of what we thought was the most relevant part in our thesis.
