It is often assumed that three-dimensional topographic maps provide more effective route planning, navigation, orientation, and way-finding results then traditional two-dimensional representations. The research reported here investigates whether three-dimensional spatial mappings provide better support for route planning than two-dimensional representations. In a set of experiments performed as...

In cable trench construction, one of the tasks for engineers is to select a suitable route to minimize construction cost and obstructions. This paper discusses the development of a Geographic Information Systems (GIS)-based Customized system to automate the process of optimum shortest path finding for routing of underground power supply cable between any two substations. It combines the spatial...

During route discovery of mobile ad hoc network, broadcasting of route request and route reply packets are the essential operations for finding the path between two ends. In such situations, intermediate node which may or may not belongs will participate in route discovery process, update routing table and rebroadcast the route discovery packets again to its neighboring nodes. Finally optimal p...

Finding a scenic route between two locations is a common trip planning task, in particular for tourists and recreational travelers. For the automated computation of a scenic route in a trip planning system it is necessary to identify which attributes of a route and its surroundings are associated with attractive scenery. This study uses a route choice model, more specifically a Path Size Logit ...

Current navigation services assume wayfinders new to an environment. In contrast, our focus is on route directions for wayfinders who are familiar with the environment, such as taxi drivers and couriers. We observe that people communicate route directions to these wayfinders in a hierarchical and granular manner, assuming some shared knowledge of the environment. These route directions do not f...

Currently, Global Positioning Systems and other route-finding systems work well for wheelchair users outdoors. Indoor information is usually not provided. However, it is more important for wheelchair users to know the indoor maps of routes accessible to them. Where the closest elevator is, which door is accessible to them, and how long it takes to get to a destination are major route-finding pr...
