It outlines critical physical dimensions including vehicle length, width, axle counts, and overhang measurements for road infrastructure planning. Additionally, the document details operational parameters such as steering lock angles, articulating angles, and minimum turning radii based on data from the City of Saskatoon Infrastructure Services Department and Alberta Infrastructure highway standards. These specifications are essential for civil engineers and urban planners involved in designing arterial roads, expressways, and freeways to ensure adequate traffic accommodation and safety. The technical data provided ensures that roadway geometry is compatible with the physical capabilities and turning requirements of large commercial transport vehicles.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/design-vehicles-for-arterials-expressways-freeways-and-highways-geometric-design-standards/648244/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/design-vehicles-for-arterials-expressways-freeways-and-highways-geometric-design-standards/648244.png","ImageObject",300,407,{"name":92,"@type":93},"Theodore","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-04","2026-10-23",true,{"@type":102,"interactionType":103,"userInteractionCount":29},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What
