Abstract

• Traffic Simulation
• Moving past optimal
• Model Types
• Fluid Flow
• Agent Based Modeling

3
Introduction

• Communication
• Calculation- information flow
• Human behavior
• Reaction and Response

4
Background

• Traffic Jams
• Optimization of Models
• Variable speed limits
• Kai Nagel
• Steen Rasmussen
• Micro models

5
Development

• World and environment
• Vehicles- all private information
• Reaction Algorithm
• Turning Algorithm
• Density versus Flow

6
Fluid Flow Model

• Opposing theory
• Terrible at small perturbations
• Butterfly effect
• Mostly kept in the United States
• Slow to change to agent based

7
Reaction Algorithm

• Delta X
• Smallest distance on same line of travel
• Function of two velocities
• Previously linear
• Not true human behavior, more development

8
Turning Algorithm

• All angle-based
• Trigonometric Functions
• Leads to issues in detection algorithm for a 2d
  system

9
Results

• Traffic jam moving backwards- speed trap
• Graphical analysis of density versus flow
• Information sharing to alleviate traffic
• Adjustable speed limits
• Removing traffic impediments- stop signs

10
Conclusion

• Traffic is dependent on human specific behavior
• More factors need to be taken into account
• Further research
• Micro model ? macro model
• Compilation of parts
