Dependence between radiuses of curves of off-ramps and transport energy onsumption
within left- and right-turning directions of traffic of flyunder crossings with the ngineering
and planning solution of “cloverleaf” type with the help of software system PTV VIS-SIM
is investigated. Optimum values, from the point of view of minimization of energy onsumption of a transport flow, of their radiuses of curves are defined.
