This paper presents a method for determining the circulatory and entry widths based on a two-dimensional vehicle dynamics model that involves a system of differential equations of curvilinear motion. The method considers the interactions between a vehicle and road geometric elements, including tire sideslip, vehicle weight, vehicle speed, and vehicle stability. Three design vehicles are considered: intermediate semitrailer (WB-12), interstate semitrailer (WB-20), and city transit bus (CITY-BUS). Design guidelines for the required circulatory width are established for different circulatory speeds (0-60 km\/h) and different inscribed circle diameters (30-80 m). To simplify the guidelines, for each design vehicle and for each inscribed circle diameter (ICD) the regression model of circulatory roadway width as a power function of circulatory speed was fitted. The results show the efficiency of the proposed method which provides smaller values of circulatory roadway widths than those of current methods.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786139447701\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786139447701","offer_id":39464323579997,"sku":"9786139447701","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/9cb0597b-0411-4ca5-819e-c37055d43bba.jpg?v=1769925961","url":"https:\/\/shop.autorenwelt.de\/products\/guideline-for-roundabout-circulatory-width-based-on-vehicle-dynamics-von-maksym-diachuk-said-easa","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
