Movement of a Vehicle in a Turn

Prema nekom najosnovnijem razmišljanju, kretanje motornih vozila temelji se na kotrljanju kotača. DogaĎa se pod utjecajem različitih otpora i sila, a u cestovnom prometu uvjetovano je oblikovnim i prometnim elementima trase ceste. Različite sile otpora vožnje (osnovne, vanjske i unutarnje) koje djeluju na motorno vozilo pri kretanju moraju se savladati vučnom silom. Posebna pažnja se pri tome pridaje kretanju motornih vozila u zavoju, gdje se pojavljuju utjecaji centrifugalne i centripetalne sile. Kretanje vozila u zavoju, s brzinama većim od granične brzine odreĎene projektom i konstrukcijskim elementima trase ceste, može dovesti do zanošenja ili prevrtanje vozila, što negativno utječe na samu sigurnost cestovnog prometa. Kako ne bi do toga došlo, prometno-tehničke elemente ceste u zavoju potrebno je uskladiti s mjerodavnim motornim vozilom, njegovim tehničkim obilježjima, te uvjetima okoline na koje se nailazi na odreĎenom području ceste.According to some basic thinking, motor vehicle movement is based on rolling wheels. It happens under the influence of various resistances and forces, and in road traffic it is conditioned by the shape and traffic elements of the road route. The various driving resistance forces (basic, external and internal) acting on the motor vehicle when moving must be overcome by the tractive force. Particular attention is paid to the movement of motor vehicles in a turn, where the effects of centrifugal and centripetal forces occur. Turning the vehicle at a speed greater than the speed limit determined by the design and structural elements of the route may cause the vehicle to become bogged down or overturned, which negatively affects the road traffic safety itself. In order to avoid this, the traffic-technical elements of the bend must be harmonized with the relevant motor vehicle, its technical characteristics, and the environmental conditions encountered in a particular area of the road
