Synopsis:

1. Basic mathematical description of vehicular traffic - macroscopic and microscopic quantities, relations between them, fundamental diagram and phase map.

2. Empirical knowledge about traffic flow - methodology of traffic data evaluation, 3s-unification procedure, two-phase theory, three-phase theory, VHM and link to capacity calculations in physics of traffic.

3. Traffic models - general overview, classification of models, examples, Greenberg’s macroscopic model and its solution, Montroll’s microscopic model and its solution.

4. Lighthill-Whitham model - formulation and theoretical solution, Cole-Hopf transformation, formulation of associate Cauchy problem and its solution in distributions, Burgers equation.

5. Cellular traffic models - Nagel-Schreckenberg model, Fukui-Ischibaschi model, model TASEP and its theoretical solution by MPA.

6. Thermodynamic traffic models - variants, classification by range and type of potential, Hamiltonian description, general solution methodology, solution of short-range model, connection between thermodynamic models and balance particle systems, solution of middle-ranged model with logarithmic potential.

7. Vehicular Headway Modeling - an insight into the issue, empirical and theoretical knowledge in a given area, criteria for admissibility of headway distributions, statistical rigidity and changes in its course, derivation of statistical rigidity for thermodynamic gas.

8. Statistical properties of traffic flow - Poisson and semi-Poisson mode of transport, supra-random traffic states, their detection.
