free speed

We used speckle visibility spectroscopy to measure the time-resolved dynamcis of avalanching down the inclined surface of a granular material in a half-full rotating drum operating in the slumping regime. The distribution of the avalanche period, t(d), rest time between them, t(r), and peak particle velocity fluctuation, δv(p)(2), are all normally distributed. While the distributions of the two...

Determining Free-Flow Speed on Different Classes of Rural Two-Lane Highways

Journal: :Promet-traffic & Transportation 2023

Current analytical free-flow speed models consider all rural two-lane highways as the same road type despite their different functional significance in network. The aim of this paper is to develop a prediction model for function limit and geometric characteristics classes highways. research was conducted on 50 representative sections two equipped with automatic traffic counters Serbia. In order...
