Large Scale Pedestrian Evacuation Modeling Framework Using Volunteered Geographical Information

Evacuation Modeling Framework Using Volunteered Geographical Information. In Large Scale Pedestrian Evacuation Modeling Framework Using Volunteered Geographical Information

With rising instances of extreme events and urban settlements, this paper outlines a pedestrian evacuation modeling framework using volunteered geographical information from OpenStreetMap and simplified queuing-network model to estimate evacuation time, detect bottlenecks and test different evacuation strategies. An example case of a total city wide evacuation is presented for a selection of UK...

Evacuation time estimate for total pedestrian evacuation using a queuing network model and volunteered geographic information.

Estimating city evacuation time is a nontrivial problem due to the interaction between thousands of individual agents, giving rise to various collective phenomena, such as bottleneck formation, intermittent flow, and stop-and-go waves. We present a mean field approach to draw relationships between road network spatial attributes, the number of evacuees, and the resultant evacuation time estimat...

Modeling the Evacuation of Large-Scale Crowded Pedestrian Facilities

Most of these accidents occur as pedestrians try to evacuate the facility in panic mode. Thus, increasing attention has been given to planning for the evacuation of these facilities by considering of all possible emergencies. The objective is to minimize the period required to evacuate a facility while ensuring the safety of all pedestrians. Evaluation of the effectiveness of an evacuation plan...

Microscopic dynamics of a large-scale pedestrian evacuation model

Numerous models have been developed for estimating the time required to evacuate from a variety of places under various conditions. For high-traffic places, such as commercial and industrial buildings, it is vital to be able to accurately calculate the evacuation time required in order to ensure the safety of the occupants. To this end, various models of pedestrian dynamics have been proposed, ...
