[PDF][PDF] PLEdestrians: A Least-Effort Approach to Crowd Simulation.

SJ Guy, J Chhugani, S Curtis, P Dubey… - … on computer animation, 2010 - diglib.eg.org
We present a new algorithm for simulating large-scale crowds at interactive rates based on
the Principle of Least Effort. Our approach uses an optimization method to compute a …

Reciprocal n-Body Collision Avoidance

J Van Den Berg, SJ Guy, M Lin, D Manocha - Robotics Research: The 14th …, 2011 - Springer
In this paper, we present a formal approach to reciprocal n-body collision avoidance, where
multiple mobile robots need to avoid collisions with each other while moving in a common …

Simulating heterogeneous crowd behaviors using personality trait theory

SJ Guy, S Kim, MC Lin, D Manocha - Proceedings of the 2011 ACM …, 2011 - dl.acm.org
We present a new technique to generate heterogeneous crowd behaviors using personality
trait theory. Our formulation is based on adopting results of a user study to derive a mapping …

The hybrid reciprocal velocity obstacle

J Snape, J Van Den Berg, SJ Guy… - IEEE Transactions on …, 2011 - ieeexplore.ieee.org
We present the hybrid reciprocal velocity obstacle for collision-free and oscillation-free
navigation of multiple mobile robots or virtual agents. Each robot senses its surroundings and …

Clearpath: highly parallel collision avoidance for multi-agent simulation

SJ Guy, J Chhugani, C Kim, N Satish, M Lin… - Proceedings of the …, 2009 - dl.acm.org
We present a new local collision avoidance algorithm between multiple agents for real-time
simulations. Our approach extends the notion of velocity obstacles from robotics and …

Universal power law governing pedestrian interactions

I Karamouzas, B Skinner, SJ Guy - Physical review letters, 2014 - APS
Human crowds often bear a striking resemblance to interacting particle systems, and this has
prompted many researchers to describe pedestrian dynamics in terms of interaction forces …

Reciprocal collision avoidance with acceleration-velocity obstacles

J Van Den Berg, J Snape, SJ Guy… - … on Robotics and …, 2011 - ieeexplore.ieee.org
We present an approach for collision avoidance for mobile robots that takes into account
acceleration constraints. We discuss both the case of navigating a single robot among moving …

A statistical similarity measure for aggregate crowd dynamics

SJ Guy, J Van Den Berg, W Liu, R Lau, MC Lin… - ACM Transactions on …, 2012 - dl.acm.org
We present an information-theoretic method to measure the similarity between a given set of
observed, real-world data and visual simulation technique for aggregate crowd motions of a …

BRVO: Predicting pedestrian trajectories using velocity-space reasoning

S Kim, SJ Guy, W Liu, D Wilkie… - … Journal of Robotics …, 2015 - journals.sagepub.com
We introduce a novel, online method to predict pedestrian trajectories using agent-based
velocity-space reasoning for improved human–robot interaction and collision-free navigation. …

Smooth and collision-free navigation for multiple robots under differential-drive constraints

J Snape, J Van Den Berg, SJ Guy… - 2010 IEEE/RSJ …, 2010 - ieeexplore.ieee.org
We present a method for smooth and collision-free navigation for multiple independent
robots under differential-drive constraints. Our algorithm is based on the optimal reciprocal …
