84 PART | II ITS users
driving systems at all scenarios and will support the development of naturalis-
tic, efficient, and safe ITS.
Apart from safety, which is the number one concern for ITS, comfort is an-
other asset for ITS users, which however, is difficult to be assessed objectively.
The evaluation of comfort may differ among users so few studies and applica-
tions have already tackled his problem. The existing communication interfaces
of most ITS applications have been designed for young or middle-aged drivers
and are rarely suitable for older drivers. Fewer ITS applications exist for pe-
destrians, cyclists, or impaired people and their comfort is dependent on local
initiatives and regulations, if there exist any. Only a few countries consider
pedestrians and VRUs as high priority users giving them their space and protec-
tion mechanisms. In such cases the role of ITS is important, since they control
speed limits, they support pedestrian traffic signals and pedestrian warnings and
provide controlled access to car-free areas.
6.7 Conclusions
This chapter has discussed on ITS users, as well as how their behavior is affect-
ed by ITS development. The analysis has shown various levels of influence on
ITS users, mostly focusing on drivers, passengers, pedestrians, transport profes-
sionals and other VRUs. Last but not least, the implications of using ITS are not
limited to the users of the systems, but they may also be extended to the drivers
whose vehicles are not equipped with similar systems, albeit they interact with
users of the systems. But as there is no in-depth research on this direction, as it
is not possible to specify parameters in this direction.
