Abstract
A three-dimensional urban road system capable of intensively utilizing land and avoiding traffic jam, including a straight section, a longitudinal slope section and an intersection. The straight section and the intersection are connected to form a road network. The longitudinal slope section is connected with the straight section, realizing connection between the straight section and the ground. The straight section includes a bottom road, a parking layer and a running layer; parallel ramps for small cars only arranged such that small cars in the straight section can switch among the three layers. Roads are changed into three layers: the upper running layer for small cars; the middle parking layer, a transfer layer for parking and connecting the ground road and the upper running layer; and the bottom road for large vehicles. Large vehicles and small cars are completely shunted, thus effectively solving the problem of traffic jam.
