A Traffic Simulation Model Allowing For Wide-ranged Vehicle
Communication (being altered/worked on)
Timmy Galvin(Third Quarter)
Abstract
Traffic Simulation Moving past optimal Model Types:
Fluid Flow Agent Based Modeling
Introduction
Communication Calculation- information flow Human behavior Reaction and Response
Background
Traffic Jams
– What causes a jam? Optimization of Models Variable speed limits
– Inferred effects Kai Nagel Steen Rasmussen
Micro models
Fluid Flow Model
Opposing theory Terrible at small perturbations
Butterfly effect Mostly kept in the United States
Slow to change to agent based
Development
World and environment Vehicles- all private information Reaction Algorithm
– Function of individuality User-definition Density versus Flow
Reaction Algorithm
Delta X Smallest distance on same line of travel Function of two velocities Previously linear
– Not true human behavior, more development
Looking forward through intersections
Intersections
• Defined by user
• N number of intersections
• Stoplights created with preset timing
Results
Traffic jam moving backwards- speed trap Graphical analysis of density versus flow Traffic congestion and travel time How do different variables affect traffic patterns Altering timing on a system-wide scale
– Networking traffic lights
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
