Understanding the needs of people who are blind or partially sighted allowed us to identify solutions with the potential to satisfy those needs. However, selecting technologies that are practical to implement required a closer look at the current accessibility of public transportation information and the systems that support it. In addition to considering how information can be accessed, we investigated solutions that have been previously attempted to understand why different types of solutions were not effective.
This portion of our research aims to help us answer these questions:
● How is information regarding public transit schedules reported to the public?
● What technologies have been considered or implemented to improve the accessibility of information in public transportation?
● If some technologies have been used in the past to improve the accessibility of information, why are they no longer used?
● What other factors prevent these technologies from solving the problems faced by the blind and partially sighted community?
We performed observations to understand how the public transportation system works. We completed these observations to see where the system was lacking, where companies could make improvements, and to witness some of the challenges that the blind and partially sighted commuters face while traveling via public transit. Our observations did have some limitations. We are not blind or partially sighted and therefore we do not know if bus drivers would pay special attention after seeing someone with a white cane or a guide dog. We did our best to observe stations in which there would be a larger presence of the blind and partially sighted population, but even so, we saw very few.
3.3.1. Infrastructure Survey of Stations
For qualitative evidence, we evaluated current accommodations for blind and partially sighted commuters in the busiest stations in the Copenhagen public transit system. We evaluated Copenhagen Central, Nørreport, and Valby stations. We created a detailed protocol to evaluate these stations properly (Appendix 3.4).We started by using a map of the area. We plotted where we stood in the station, which can be seen as the human figure on the maps (Appendix 3.5). Initially, we determined whether there were tactile indicators present in the stations. We noted where the bus or train stopped, whether it was by the post outside for buses, or whether it was aligned with the current tactile door indicators. These qualitative results aided us in determining other problems the blind and partially sighted may face in the stations, and which stations are most problematic.
3.3.2. Observation in Buses and Trains
In order to understand the amount of information that a commuter receives on a bus or a train while in transit, we created a protocol for observing buses and trains. We focused on the presence and content of audio announcements inside the vehicles, and if or when the vehicles announced each stop. The observation protocol for the inside of buses and trains is outlined in Appendix 3.6. The observation protocol specified the length of the observation, where the observer should sit, and which data to note. We recorded the time of any audio announcement and the time at which the bus and train stopped, including stops that were not announced. Our main goal of these observations was to keep track of any audio announcement inconsistencies. Data for the time and content of audio announcements relative to the bus or train route were recorded on data sheets. An example can be found in Appendix 3.7.
3.3.3. Observation of Announcements on Train Platforms
In order to evaluate the quality of audio announcements inside stations, we first outlined an observation protocol to ensure we collected the data in a consistent, organized manner (see Appendix 3.8). For each announcement on the platform, we noted the time and the content of the
announcement. In order to keep track of when an audio announcement played relative to the time of a train arriving or departing, our team kept detailed records of audio announcements heard on the platform and in the vehicle. An example of how we recorded these data is in Appendix 3.7. When the bus or train arrived, we noted its identity, time of arrival and departure, the time at which the doors opened and closed, whether there were any audio indicators that the doors were opening, and what track that train was departing from. From these data, we wanted to conclude which stations or modes of transport have announcements that have inconsistent audibility or content.
3.3.4. Observation of Bus Stops
To fully understand how the bus system works in Copenhagen, our team created another set of guidelines in order to observe and obtain as much information as possible. These guidelines are given in Appendix 3.9. We made sure to observe during rush hour, which in our case was around 15:00 and 17:00h. In our observations, we noted the identity of the bus, the time the bus arrived, how many buses came by, how many buses stopped at their designated stop, and how many buses stopped behind another bus at their stop. From our observations, we gained a better understanding of how congested these stops can become, as well as how confusing it can be for someone who is blind or partially sighted to find the correct bus when it does not stop at the designated post.
3.3.4. Evaluation of Mobile Phone Applications
We also evaluated mobile phone applications commonly used by those who are blind or partially sighted. These applications were identified using the results of the survey discussed in Section 3.2.1, and the results of our interviews with members of the blind and partially sighted community. We compared the information available on accessible applications to the information available on
applications created for sighted commuters, identifying any information lost when the applications were made accessible. In order to evaluate the accessibility of these mobile phone applications, we met with one of our sponsors and asked him to demonstrate how one would use each app with a screen reader on an iPhone. Our sponsor demonstrated how to use three out of four applications while we observed
and noted which of their features are accessible, and where features began to fail a blind or partially sighted user. The applications we asked our participant to evaluate were Afgange, Rejseplanen, and DSB. These qualifications and features can be found in Appendix 3.10. The qualitative evidence found in our evaluation of applications aided us in identifying the specifications for a useful mobile phone application. Also, we were able to determine which applications or accessible feature improvements we should recommend to the Danish Association of the Blind, as well as the creators and maintainers of these applications.
