This invention relates to a method for determining an indicator value (Z) for statistically characterizing a location-related event description acquired by at least one vehicle, wherein, based on a road or navigation map, road segments with no inflow and no outflow are identified, with a segment length greater than or equal to a predetermined minimum segment length. Adjacent identified road segments are connected to form a road segment chain (10) having a start point (11) and an end point (12). An event description, including the vehicle's geographic location (P1, P2) and at least one parameter of the vehicle's environmental model, is acquired and transmitted to an analysis system. The analysis system assigns the nearest road network node (O1, O2) of the road segment chain (10) to the geographic location (P1, P2) of the event description accordingly, the nearest road network node being described by a longitudinal distance (L, L1, L2) relative to the start point (11) of the road segment chain (10). For at least one road segment chain (10), a curve of the density value (p) of the event description with respect to the longitudinal distance (L, L1, L2) to the starting point (11) is determined by means of a kernel density estimator with a predetermined bandwidth. The curve of the density value (p) is transformed into a Z curve (Z1, Z2) of the Z value (Z) with zero mean relative to the bandwidth by means of bandwidth-based local Z-normalization.

The utility model relates to a kind of double-sided photovoltaic anti-glare board and photovoltaic power generation system.A kind of double-sided photovoltaic anti-glare board, including photovoltaic anti-glare panel and base, the photovoltaic anti-glare panel and the base fixed connection or rotary connection;The photovoltaic anti-glare panel includes perovskite photovoltaic assembly.The double-sided photovoltaic anti-glare board of the utility model makes full use of the characteristics of road median strip, provides supplementary electric energy for the electric equipment near road, energy saving and environmental protection.When photovoltaic anti-glare panel and base are rotary connection, the angle of photovoltaic anti-glare panel can be adjusted according to the different azimuth change of sun in different seasons, to achieve the maximum use of light energy.Compared with ordinary anti-glare board, double-sided photovoltaic anti-glare board can increase land and illumination utilization rate, and the electric energy emitted can also be supplied to street lamp and other electric traffic equipment, with great economic and environmental benefits.
