Robot navigation in crowded public spaces is a complex task that requires addressing a
variety of engineering and human factors challenges. These challenges have motivated a …

Crowd simulation has emerged in the last decade as a widely used method of visual effects,
computer games, and urban planning, etc. The improvement of hardware performance and …

Trajectory prediction has been widely pursued in many fields, and many model-based and
model-free methods have been explored. The former include rule-based, geometric or …

In the everyday exercise of controlling their locomotion, humans rely on their optic flow of the
perceived environment to achieve collision-free navigation. In crowds, in spite of the …

The typical elastic surface or curve simulation method takes a Lagrangian approach and
consists of three components: time integration, collision detection and collision response …

Virtualized traffic via various simulation models and real‐world traffic data are promising
approaches to reconstruct detailed traffic flows. A variety of applications can benefit from the …

Collective motions are common in crowd systems and have attracted a great deal of
attention in a variety of multidisciplinary fields. Collectiveness, which indicates the degree of …

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 …

Hajj, the annual pilgrimage to Makkah, is one of the most massive gathering events in the
world. It is a mandatory religious activity, once in a lifetime for every sane well-off Muslim …

Recently the Affine Particle-In-Cell (APIC) Method was proposed by Jiang et al.[2015;
2017b] to improve the accuracy of the transfers in Particle-In-Cell (PIC)[Harlow 1964] …
