Traffic Light System: To relax the authentication constraints for enhanced usability, a traffic light system is embedded in the PBAF.
The designed system algorithms and methods gives usability to detect traffic signs elements inside image obtained from camera.
Another key factor is data amount transit for getting or setting information within the system which results in the usability being improved by data traffic efficiency.
Given the results of the online examination phase and in order to minimize the usability issues, we set up the traffic light system as shown in Figure 2.
If this is a room where you will be working, such as a sewing room, kitchen, studio, or garage, a well-placed table or island can make a world of difference, both in the flow of traffic and in the usability of the space for work.
The traffic light system enhances the usability of PBAF method by relaxing authentication constraints.
Here, we made use of the advantages of the domain expertise of the usability experts as well as the rail traffic controllers.
We have analysed the usability of questions in the online examination and traffic light authentication phases.
Differences between regions such as culture, environment and traffic context can influence the needs, usability and acceptance of IVIS.
The value of the proposed methodology is mainly its usability as it can be applied in absence of traffic data, which are often difficult to find, especially in case of pedestrian traffic.
