Walking in the Shade: Shadow-oriented Navigation for Pedestrians
Pages 677 - 680
Abstract
Excessive exposure to the sun and the resulting heat poses health risks to pedestrians in hot weather. To mitigate these risks, we propose a shadow-oriented navigation system that offers cooler and more convenient walking routes by simulating shadows. Our system integrates a manually corrected pedestrian network from OpenStreetMap with LoD2 3D city models, using a ray tracing module for real-time shadow simulation. It optimizes routes to be either cooler or shorter based on user preferences, with easy verification through 3D scene visualization. Our navigation system has been implemented in a study area in Munich, Germany, with further discussions on the technical feasibility and challenges of extending it to larger areas.

A proposal of IndoorGML extended data model for pedestrian-oriented voice navigation system
ISA '15: Proceedings of the Seventh ACM SIGSPATIAL International Workshop on Indoor Spatial AwarenessWe propose Landmark-Conscious Voice Navigation as one type of a pedestrian navigation system, which navigate users by only voice guidance. It is necessary to standardize data model in order to use this system widely. In a previous paper[1], we ...
Study on the Pedestrian Network Model Oriented to Pedestrian Navigation
MUE '09: Proceedings of the 2009 Third International Conference on Multimedia and Ubiquitous EngineeringWalking is one of the most elementary traffic modes nowadays. The more frequently the road network changes, the more urgent the desire of pedestrian navigation becomes. To realize pedestrian navigation, pedestrian network model must be established ...
