- Abstract
Variable speed-limit for complicated traffic environment of freeway lacks quantitative rules and decision -making technology. This paper establishes comprehensive quantitative measuring & evaluating model, depending on the values of 7-factor indices (including: visibility, wind force, rainfall/snowfall, pavement icing/snow thickness, traffic level of service), employing the relation model of traffic ‘flowrate- density-velocity’ and the calculating model of vehicle’s stopping-sight-distance & critical-skidding- equilibrium, incorporated with authentic technical standards, based on single-factor fuzzy measuring & evaluation, executes multi-factor comprehensive measuring & evaluation on the reasonable limiting-speeds subject to given complicated traffic environment, so as to present the quantitative rules and tactics of the variable speed-limit of freeway.
