Pedestrian network data collection through location-based social networks

Abstract: The increasing capabilities of mobile devices and their mobile positioning technologies have shown great promise in location-enabled applications such as navigation systems. One of the essential components of a navigation system is a spatial database as it provides the base data to perform navigation and routing functions, among others. With the popularity of vehicle navigation systems, road network databases are now well developed and well suited for vehicles traveling on roads. However, road networks are not suitable for pedestrian navigation systems as pedestrians do not walk along the middle of street lanes and are not constrained by the boundaries of the road. Consequently, pedestrian network data is needed in location-enabled applications for pedestrians and other applications including transportation planning and physical activities study. Due to the lack of availability of pedestrian network data, new approaches for acquiring and maintaining pedestrian network data that are efficient and cost effective are needed. This paper presents a new approach that is based on location-based social networking for collecting pedestrian network data. The proposed approach stems from the concept of collaborative mapping where pedestrian network data can be collected by members of a social network recording GPS trajectories. A prototype based on a framework called Social Navigation Network (SoNavNet) for sharing and recommending navigation related information is also discussed.

Abbreviated directions for route navigation

Abstract: A geographic navigation system for segmenting a received set of instructions (or directions) that guide a user over a geographic route from a starting location to an ending location, and then abbreviating a subset of the instructions related to the inexact or familiar regions into a more concise and relevant form, yet retain all the information for guiding the user on the trip. Route segmentation occurs before instruction abbreviation by segmenting the route into multiple logical components in which abbreviation can be applied. After the need for instruction abbreviation is recognized and the route is segmented, techniques and designs are employed to generate understandable strings that describe the abbreviated directions as well as controls that allow optimization of the user experience.

Spatial Navigation for Context-Aware Video Surveillance

Abstract: Interactive spatial navigation for video surveillance networks can be difficult. This is especially true for live tracking of complex events along many cameras, in which operators must make quick, accurate navigation decisions on the basis of the actual situation. The proposed spatial navigation interface facilitates such video surveillance tasks.

Navigation method, system or service and computer program product

Abstract: A navigation method, system, service and computer program product may include providing enhanced travel instructions in response to receiving a destination and detailed travel directions from at least one waypoint to the destination being available.
