Analytical tools are designed to help people understand the complex relationships associated with freeway performance and traffic breakdown. Emphasis is placed on: (1) Traffic noise or volatility; (2) Driver behavior and safety; and (3) Stochastic modeling, models that explain breakdown and performance.
