Interactive Traffic Simulation for Efficient Movement Analysis

This research focuses on a hybrid simulation of large-scale traffic, blending agent-based and continuum-based approaches. The method aims for fast, scalable, and visually interactive traffic simulation to optimize analysis of contact, collision, and congestion in dynamic traffic scenarios.

Presentation Transcript

  1. Contact, Collision and Congestion Nobuyuki Umetani

  2. Interactive Hybrid Simulation of Large-Scale Traffic Jason Sewall (Intel Corporation), David Wilkie, Ming C. Ling (University of North Carolina)

  3. Motivation • Efficient traffic simulation • Fast • Scalable • Interactively moving visible region

  4. Method • Visible Region -> Agent based approach • Solve for each car speed & position • Invisible Region -> Continuum based approach • Solve for car density average velocity Invisible (Continuum Based ) Visible( Agent Based )

  5. Agent Generation from Continuum data • Stochastic Theory • Model Car distances with Poisson’s distribution • For the accuracy, λ is function of x, not constant

  6. Performance – Scalability

  7. Pattern-Guided Smoke Animation with Lagrangian Coherent Structure Zhi Yuan, Fan Chen, Ye Zhao (Kent State University)

  8. Motivation • Fit hi-res fluid simulation to low-res simulation • hi-res : detail, expensive • Low-res : no detail, cheap, controllable Hi-Res Low-Res

  9. Method • Extract skeleton from low-res fluid simulation • Fluid skeleton : Lagrangian Coherent Structure(LCS) • LCS is computed from FTLE(finite-time Lyapunov exponent) • Assimilate high-res fluid velocity to low-res at LCS

  10. Computation of LCS FTLS 0 thinning 10 thinning 5 thinning

  11. Interference Aware Geometric Modeling David Harmon (New York University), Daniele Panozzo (University of Genova), Olga Sorkine (ETH Zurich), Denis Zorin (New York University)

  12. Motivation • Deform Surface avoiding penetration • Interactive Speed • Various type surface • Close/non-close mesh • Subdivision surface

  13. Method • Space-time frame work • Space-time Interference Volume(STIV)

  14. Framework

  15. Imperceptible Relaxation of Collision Avoidance Constraints in Virtual Crowds Richard Kulpa, Anne-Helene Olivier Jan Ondrej, JulienPettre (INRIA, Grenoble, France)

  16. A Hybrid Iterative Solver for Robustly Capturing Coulomb Friction in Hair Dynamics Gilles Daviet, Florence Bertails-Descoubes, Laurence Boissieux (INRIA, Grenoble, France)
