Pedestrian headways - Reflection of territorial social forces

The main stress is put on natural choices of mutual interaction represented by logarithmic and hyperbolic potentials leading to gamma and generalized inverse Gaussian distribution respectively. We show that the time headway distribution does not sufficiently reflect the differences between such distributions. The tools related to spectral rigidity and compressibility are chosen instead so as to predict the territorial social forces more accurately. Surprisingly, pedestrian flow seems to show a higher level of synchronization (lower compressibility) than vehicular flow.
