Target load classes Road superstructure Hamburg

The dataset contains the target load classes of the road superstructure for the Hamburg City Road Network. The dimension-relevant load B (sum of the weighted equivalent 10-t axis transitions in the period of use) for determining the target load classes was determined in accordance with Method 1.2 of the Guidelines for the Standardisation of the Overhead Structure of Traffic Areas (RStO). With the exception of the gradient factor fz, all other factors included in the corresponding formula were determined from the data stored in the Hamburg Road Information Bank (e.g. average daily heavy traffic load, lane width, number of lanes). Only for the determination of the slope factors there are no grid data, therefore a maximum longitudinal inclination ≤ 6 % was applied for the calculations. Furthermore, the calculation in the expansion areas of the nodes could not be calculated, as road widths and number of lanes are generally not consistent. For the line network connection it was therefore necessary to close the intersection between the calculation results meaningfully. For construction preparatory measures, the target load classes in the line display are therefore only partially suitable, in nodes a detailed examination is absolutely necessary. The data record explicitly only represents the target load class and not necessarily the actual load class currently present on the respective road.本数据集涵盖汉堡城市道路网的道路上部结构目标荷载等级。 用于确定目标荷载等级的与尺寸相关的荷载B（即使用期内加权等效10吨轴次总和），系按照《交通区域上部结构标准化指南（RStO）》的1.2方法确定。除坡度系数fz外，对应计算公式中的其余所有参数均取自汉堡道路信息库的存储数据（例如日均重载交通荷载、车道宽度、车道数量）。 仅在坡度系数的确定环节无栅格数据可用，因此本次计算采用最大纵向坡度≤6%的取值。此外，由于道路宽度与车道数量通常并不统一，道路节点扩展区域内的计算无法完成。为实现线网衔接，需对计算结果的交叉口进行合理闭合。针对施工筹备工作，线网展示中的目标荷载等级仅具备部分适用性，节点区域需开展详尽核查。 本数据集仅明确表征目标荷载等级，并非对应道路当前实际存在的荷载等级。
