The motor road cross-section on rise and slopes is composed of, at least two roadway driving lanes, roadsides and slopes and comprises a dual-slope surface arranged on every driving lave and on roadsides with slopes. Note here that the dual-slope surface slopes, within every driving lane, ...

The grade location needs to consider the cross section composition form, chooses the appropriate road pavement bed, the definite side slope form, draws up the cross-section of road chart, the computation cubic meter of earth and stone and carries on mixes.Pavement design including road surface ch...
If the current vehicle is required to cross the dotted line to complete a lane change behavior at the moment t8 in the behavior planning layer, then the vehicle is required to complete Δd action in the lateral direction and Σ action in the longitudinal direction. The functions of s and ...
Finally, the width and slope of the roads were computed, and the road clusters were extracted by Object-Based Image Analysis (OBIA). Li et al. (2016a) extracted four class features (distance, intensity, Full Width at Half Maximum (FWHM), and back scattering cross-section) by waveform ...

In turn, WFD can be estimated using the following expression:WFT=0.01485TXD0.11·L0.43·I0.59S0.42-TXDwhere L is the drainage path length (m), I is the rainfall intensity (mm/h), and S is the pavement cross slope (m/m). Fig. 1b illustrates how HPS (solid line, V@165) and WFD...
5.2.3-1. The slope of the mitigation section is 3 % and the length shall be in accordance with the provisions of article 2 of this article. The minimum length of the longitudinal slope at all levels should be greater than or equal to the value of table 5.2.3-2, ...
