Discrete thermodynamical modelling of traffic streams
Original language description
We present some important results of a robust statistical analysis applied to freeway traffic data measured by induction double-loop detectors. We demonstrate that the microscopic quantities of traffic flow (e.g. clearance distribution, mental strain coefficient, spectral rigidity and so on) markedly depend on an actual position of the traffic sample in the fundamental diagram (traffic flux vs. traffic density). Furthermore, we show that clearance distribution and spectral rigidity of the celebrated Nagel-Schreckenberg model (NaSch-model) do not correspond to realistic traffic behaviour, although such a model reproduces most of macroscopic traffic phenomena accurately. Exploiting new knowledge on local thermodynamical features of vehicular streams we introduce thermal-like variant of the cellular NaSch-model, which is powerful in both microscopic and macroscopic analysis of traffic.
