The invention provides a road speed limit value optimization method, and the method comprises the steps that a driver selects a driving speed according to a road condition, a car following effect and a traffic environment, so as to carry out the real vehicle test of a speed limit road section, and employs a GPS position indicator to collect test data; wherein the test data comprises positioning time, position coordinates and instantaneous speed; matching each piece of test data to each unit road section in the speed limit road section; for each unit road section, based on the test data matched to the unit road section, obtaining a representation speed value of the unit road section; and determining a road speed limit value of the speed limit road section based on the representation speed value of each unit road section. According to the method, the road speed limit value is determined on the basis of the actual working requirements of a traffic management department under the conditions that large-scale vehicle speed investigation does not need to be carried out and the influence of existing speed limit facilities on a driver does not need to be considered, and the method has the advantages of being easy to operate, low in cost and high in reliability.
本申请提供了一种道路限速值优化方法,所述方法包括:驾驶人根据道路条件、跟驰效应和交通环境选择行车速度,以对限速路段进行实车测试,同时利用GPS定位仪采集测试数据;其中,所述测试数据包括:定位时间、位置坐标和瞬时速度;将每一个测试数据匹配至所述限速路段中的各单元路段;针对每一个单元路段,基于匹配至该单元路段的测试数据,得到该单元路段的表征速度值;基于各单元路段的表征速度值,确定出所述限速路段的道路限速值。该方法从交通管理部门的实际工作需求出发,在不需要开展大规模车速调查,且不需要考虑既有限速设施对驾驶人影响的情况下确定出道路限速值,具有易操作、成本低且可靠性高的优势。
