20 paź 2020 · This study presents a quantitative review of the effectiveness of dynamic speed feedback signs (DSFS), which provide drivers with real-time feedback on their speed so that drivers traveling above the posted speed can slow appropriately.
Driver Feedback (DFB) signs are an effective tool in decreasing speeds in urban communities, on highways, in school zones, construction sites or special events.
This report reviews the published literature on the effectiveness of dynamics speed feedback signs (DSFSs) in reducing vehicle speeds. In Volume I, the literature review summarized the number of significant results found in studies of DSFS in a variety of contexts. It covered 43
educational tool by informing drivers how their driving behavior aligns with the posted speed limit and expected norms. This report presents evidence that DSFSs can be effective in reducing mean speeds, 85th percentile speeds, and the percentages of drivers over the speed limit in a range of contexts.
7 maj 2018 · Various studies showed that adding graphics to PCMS messages can provide advantages to traditional text messages, such as increasing legibility and improving the understanding of elderly drivers. This article synthesizes the findings of a two-phase research project aimed to investigate driver responses to graphic-aided PCMSs.
Unstaffed speed display devices, also known as speed feedback signs, which can be portable (on trailers) or permanently installed, can show drivers that they are speeding and may encourage some drivers to slow down.
Dynamic speed feedback sign (DSFS) systems are traffic control devices that are programmed to provide a message to drivers exceeding a certain speed threshold. A DSFS system typically consists of a speed-measuring device such as a loop detector, radar, or message sign, which displays feedback to drivers who exceed a predetermined speed threshold.
