Current guidelines for rounda.out circula.ory roa.wa. width a.e ba.ed on a.sta.ic m.thod tha. does not consider circula.ory speed. In a.dition, the rounda.out entry width is ba.ed on pra.tica. experience. This pa.er presents a.m.thod for determ.ning the circula.ory a.d entry widths ba.ed on a.two-dim.nsiona. vehicle dyna.ics m.del tha. involves a.system.of differentia. equa.ions of curvilinea. m.tion. The m.thod considers the intera.tions between a.vehicle a.d roa. geom.tric elem.nts, including tire sideslip, vehicle weight, vehicle speed, a.d vehicle sta.ility. Three design vehicles a.e considered： interm.dia.e sem.tra.ler （WB-12）, intersta.e sem.tra.ler （WB-20）, a.d city tra.sit bus （CITY-BUS）. Design guidelines for the required circula.ory width a.e esta.lished for different circula.ory speeds （0-60 krrgh） a.d different inscribed circle dia.eters （30-80 m.. To sim.lify the guidelines, for ea.h design vehicle a.d for ea.h inscribed circle dia.eter （ICD） the regression m.del of circula.ory roa.wa. width a. a.power function of circula.ory speed wa. fitted. Guidelines for entry width were a.so esta.lished for typica. conditions. The results show the efficiency of the proposed m.thod which provides sm.0}ler va.ues of circula.ory roa.wa. widths tha. those of current m.thods. The difference ra.ges from.0.4 to 0.6 m.for CITY-BUS, 0.7-1.0 m.for WB-12, a.d 1.3-2.0 m.for WB-20. The proposed guidelines would be useful in ca.e of spa.ia. restrictions.
