This increase in<br \/>\ndistance reflects 8 s of increased awareness of the crossing for a 30-mi\/h operating speed.<\/p>\n<p>\u2022 The results of the appearance ratings of the markings on a scale of A to F mirrored the<br \/>\nfindings from the detection distance evaluation. Participants preferred the continental and<br \/>\nbar pair markings over the transverse markings. <\/p>\n<p>\u2022 Participants gave the continental and bar pair markings similar ratings during both the<br \/>\ndaytime and nighttime. However, the transverse marking ratings differed based on the<br \/>\nlight level. The participants gave slightly better ratings (although still worse than<br \/>\ncontinental or bar pair markings) for transverse markings during the nighttime as<br \/>\ncompared to the daytime. The lower ratings during daylight conditions might be<br \/>\ndue to sun glare or shadow issues mentioned by the participants.<br \/>\n<!--more--><\/p>\n<p><a href=\"https:\/\/www.fhwa.dot.gov\/publications\/research\/safety\/pedbike\/11039\/11039.pdf\">https:\/\/www.fhwa.dot.gov\/publications\/research\/safety\/pedbike\/11039\/11039.pdf<\/a>oldId.20110514223328755<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[B&#8217; Spokes have you ever noticed that SHA uses a lot of skimpy crosswalk markings on high speed roads and wounder if they are effective?] excepts from: Evaluation of Pedestrian and Bicycle Engineering Countermeasures: Rectangular Rapid-Flashing Beacons, HAWKs, Sharrows, Crosswalk Markings, and the Development of an Evaluation Methods Report &#8211; FHWA CONCLUSIONS The conclusions from &hellip; <\/p>\n<p class=\"link-more\"><a href=\"https:\/\/wp.baltimorespokes.org\/?p=200874808\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;Transverse markings for crosswalks &#8211; not the best engineering practice&#8221;<\/span><\/a><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"open","ping_status":"1","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[10],"tags":[],"class_list":["post-200874808","post","type-post","status-publish","format-standard","hentry","category-biking-in-the-metro-area"],"_links":{"self":[{"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=\/wp\/v2\/posts\/200874808","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=200874808"}],"version-history":[{"count":0,"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=\/wp\/v2\/posts\/200874808\/revisions"}],"wp:attachment":[{"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=200874808"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=200874808"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wp.baltimorespokes.org\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=200874808"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
