In public transport, the blind and partially sighted face various problems, the main of which is that a completely blind person cannot identify the route number of a public transport vehicle that has stopped at a stop.
During approximately 2005, special remote controls were distributed to the blind in the older trolleybuses of the city of Vilnius. Unfortunately, those devices got obsolete. Later, bus route indicators and route numbers and letters were maximised. During the implementation of the electronic ticket system, public transport vehicles were equipped with external speakers. Other improvements were also made, but they were not enough, because completely blind people could not see even larger numbers and letters.
In implementing the social integration policy in the world and in Lithuania, the aim was to make public transport more accessible to people with disabilities, including the blind and partially sighted. Both Lithuanian and European legislation and the United Nations Convention on the Rights of the Disabled oblige transport companies to take appropriate measures to increase the mobility of the disabled. Vilnius City Council decision of March 21, 2018 (no. 1-1439) provided for a requirement to pay special attention to passengers with disabilities.
To improve the accessibility of Vilnius public transport services for the blind and partially sighted by providing relevant visual information with sound (voice).
Participants of the pre-commercial procurement project conducted scientific research with technical equipment supporting Wi-Fi Direct and Bluetooth standards and evaluated the possibilities of its practical application in the information system for the blind and partially sighted. Research and analysis data were provided by project participants in concept documents. Finally, the information system for the blind and partially sighted was developed, implemented in the city transport system, and tested under real conditions.
The decision to promote innovation demand implemented, and two prototypes developed and tested.
