Insects such as desert ants learn stereotyped visual routes between their nests and reliable food sites. Studies here reveal an important control element for ensuring that the route memories are used appropriately. They find that visual route memories can be disengaged, so that they do not provide guidance, even when all appropriate visual cues are present and when there are no competing guidan...

In attempting t o simulate the operation of a dynamic route guidance system, the modelling task is concerned both with the operation of the control system and with the implications this has for modelling driver hehaviour (whether or not the driver is receiving information from the controller) and network conditions. The aim of this paper is to provide an overview of the modelling issues which n...

In today’s modern and fast-paced world mobility is getting more and more important. One of the challenges with that is orientation in unknown places. Supporting technologies exist e.g. in the form of navigation devices, where most of them convey information through the auditory or visual channel. The modalities hearing and seeing have the advantage of being well explored and commonly used, but ...
