Calculation method and parameter optimization of urban road circular curve widening design
In the urban road route planning and design,because the motor vehicle in the circular curve road driving wheel,inside and outside the radius of the motor vehicle is different,the front wheel outside the radius of the circular curve is the largest,the rear wheel inside radius is the smallest and gradually curved inward.To this end,this paper analyzes three specific situations in the widening design of urban road circle curve:the widened middle lane of the rear inner lane does not overlap with the previous middle lane of the road,the road curves on both sides of the widened rear lane are not coordinated,and the lanes in the transition section of the widened rear lane do not connect smoothly,so as to make the calculation rule more scientific and reasonable,optimize its parameters,and provide a better method to solve the problem for related design.
