Editing Stop sign (section)

==Disadvantages==
Stop sign placement can pose difficulties and hazards in applications where cross traffic is not controlled by a sign or light. Relatively long distance between the stop sign and the crossroad facilitates accurate perception of the speed of approaching cross traffic, but lengthens the time and distance required to enter and clear the junction. Relatively short distance between the stop sign and the crossroad shortens the time required for safe passage through the intersection, but degrades the ability of the stopped driver to accurately perceive the speed of approaching cross traffic. Specifically, drivers approaching an intersection from beyond the [[Visual acuity#Subtended angular velocity detection threshold (SAVT)|subtended angular velocity detection threshold (SAVT)]] limit may be perceived by a stopped driver as standing still rather than approaching,<ref name="Weinberger">{{cite journal |title=Conjecture on the Visual Estimation of Relative Radial Motion |author=Hershel Weinberger |journal=[[Nature (journal)|Nature]] |volume=229 |issue=5286 |page=562 |date=19 February 1971 |doi=10.1038/229562a0 |pmid=4925353 |bibcode=1971Natur.229..562W |s2cid=4290244 |doi-access=free }}</ref> which means the stopped driver may not make an accurate decision as to whether it is safe to proceed past the stop sign.<ref name="looming"/> Whether the distance between the stop sign and the crossroad is officially short or is shortened by drivers creeping past the stop line, they can lose the [[Visual acuity#Lateral motion|visual acuity of lateral motion]],<ref name="JoV">{{cite journal |title=Spatial and temporal limits of motion perception across variations in speed, eccentricity, and low vision. |author1=Joseph S.
