چکیده
Abstract Background Heatstroke is becoming an increasingly serious threat to outdoor activities, especially, at the time of large events organized during summer, including Olympic Games or various types happenings in amusement parks like Disneyland other popular venues. The risk heatstroke naturally affected by a high temperature, but it also dependent on contextual factors such as presence shaded areas along traveling routes distribution relief stations. purpose study develop method reduce pedestrians for optimizing station placement, volume scheduling and route. Results Our experiments conducted planned site Tokyo Olympics simulated two weeks schedule indicate that planning setting stations with our proposed optimization model could effectively risk. Besides, results show supply can further heatstroke. route shortest length may not be least risk, physical environment need considered balance these factors. Conclusions This novel emergency service problem applied event scenarios multiple walking flows. To solve problem, effective developed evaluates space utilizing context-aware indicators which are determined heterogeneous data facilities, road networks street view images. We propose Mixed Integer Nonlinear Programming pedestrians, determining location each station. help organizers better prepare participate more safely.

Context-Aware Route Planning
In context-aware route planning, there is a set of transportation agents each with a start and destination location on a shared infrastructure. Each agent wants to find a shortest-time route plan without colliding with any of the other agents, or ending up in a deadlock situation. We present a single-agent route planning algorithm that is both optimal and conflict-free. We also present a set of...
