Mobilized and Mobilizable Visibility Distances for Road Visibility in Fog
Fog is a challenging problem for road safety. To estimate the fog density and estimate the meteorological visibility distance, some attempts using an in-vehicle cameras are being developed. To complete the notion of meteorological visibility, we propose to estimate the distance to the most distant visible object belonging to the road surface. We call this distance the mobilized visibility dista...
متن کاملUiTM study on road signs in Malaysia: The impact of information volume of road sign on level of visibility
This study was to investigate the information volume of road sign and level of visibility using real road sign. Five road signs of 5and 10-letter word combinations were shown randomly to the subject for 2 to 3 seconds at 30 meters initially. The road sign was moved closer to subject, 1 meter at a time until the subject saw the road sign correctly. The distance of first correct response demonstr...
متن کاملProteoglycans: Road Signs for Neurite Outgrowth
Proteoglycans in the central nervous system play integral roles as "traffic signals" for the direction of neurite outgrowth. This attribute of proteoglycans is a major factor in regeneration of the injured central nervous system. In this review, the structures of proteoglycans and the evidence suggesting their involvement in the response following spinal cord injury are presented. The review fu...
متن کاملExit Signs in Smoke: Design Parameters for Greater Visibility
A review of regulations and specifications for internally illuminated exit signs recommended or enforced by various sanctioning bodies in Canada, Great Britain and elsewhere reveals omissions and inconsistencies which may compromise the safety of building occupants in smoke. Since these problems are partly due to lack of conclusive research, a controlled psychophysical experiment was conducted ...
متن کاملOn the Diagnostic of Road Pathway Visibility
Visibility distance on the road pathway plays a significant role in road safety and in particular, has a clear impact on the choice of speed limits. Visibility distance is thus of importance for road engineers and authorities. While visibility distance criteria are routinely taken into account in road design, only a few systems exist for estimating it on existing road networks. Most existing sy...
