Crowd control has become increasingly important in urbanized military operations such as peace keeping, riot control, disaster management, emergency evacuation, and rescue operations. In this paper, we describe an architecture for simulating virtual crowd to aid in the training, planning and decision making process in the area of military operations. Our system makes use of the light-weight age...

This paper presents a model of crowd behavior to simulate the motion of a generic population in a specific environment. The individual parameters are created by a distributed random behavioral model which is determined by few parameters. This paper explores an approach based on the relationship between the autonomous virtual humans of a crowd and the emergent behavior originated from it. We hav...

Robocup Rescue is a research initiative on disaster mitigation, search and rescue problems. Rescue Simulation is a sub-domain that domain aims at increasing the understanding of disasters at a macroscopic(i.e.city-wide) level and exploring new ways for disaster management. In this graduation project, we extended the simulation with a model of human crowd behavior. Also explored is, how crowds c...

The wisdom of the crowd technique has been shown to be very effective in producing judgments more accurate than those of individuals. However, its performance in situations in which the intended estimates would involve responses of greatly differing magnitudes is less well understood. We first carried out an experiment to elicit people’s estimates in one such domain, populations of U.S. metropo...

Virtual reality, as any emerging technology is receiving a great attention from the computer graphics world. As items of real life are digitalized, virtual reality's goal is to digitalize, in the most realistic way, our environment. But few researchers have based their work on simulation of our environment under normal conditions and most are concentrated on simulation of crisis situations. Our...

While walking through a crowd, a pedestrian experiences a large number of interactions with his neighbors. The nature of these interactions is varied, and it has been observed that macroscopic phenomena emerge from the combination of these local interactions. Crowd models have hitherto considered collision avoidance as the unique type of interactions between individuals, few have considered wal...

Using a cellular automata approach we create models of people movement within buildings. Simple, local update rules capturing the movement of individuals are shown to produce realistic behaviour of crowds, that is, collections of individuals. We demonstrate how distinct crowd behaviour at constriction points is characterised using different update rules. These distinct rules are produced in an ...

Ubiquitous crowd-sourcing has become a popular mechanism to harvest knowledge from the masses. OpenStreetMap (OSM) is a successful example of ubiquitous crowd-sourcing, where citizens volunteer geographic information in order to build and maintain an accurate map of the changing world. Research has shown that OSM information is accurate, by comparing it with centrally maintained spatial informa...

Cities are drivers of economic development, providing infrastructure to support countless activities and services. Today, the world’s 750 biggest cities account for more than 57% of the global GDP and this number is expected to increase to 61% by 2030. More than half of the world’s population lives in cities, or urban areas, and this share will continue to growth. Rapid urban growth has posed b...
