Various embodiments of the present invention provide systems, methods, and computer program products for identify the probability of a particular attribute being located along a segment of interest for a driving route. In general, various embodiments of the invention involve representing the segment of the driving route by patterns of speed variations obtained from GPS elements along the segment of the driving route and using the representation as input for functions representing various types of attributes to determine the probability of a particular type of attribute existing along the segment of the driving route.

1. A method for providing a prediction of a type of attribute located along a segment of a driving route based on one or more speed variation patterns obtained from Global Positioning System (GPS) elements, the method comprising: (a) representing, via a processor, the segment of the driving route by a multi-dimensional feature vector capturing the one or more speed variation patterns; and(b) inputting the multi-dimensional feature vector into a function for the type of attribute and in response to analyzing the multi-dimensional feature vector input in the function, determining the prediction indicating whether an object of the type of attribute is physically located along the segment of the driving route. 2. The method of claim 1, wherein prior to (a) representing the segment, the method further comprises: (c) retrieving a plurality of GPS elements; and(d) for each GPS element that corresponds to one or more positions along the segment of the driving route, identifying a portion of the GPS element recorded along the segment to include in an input GPS set. 3. The method of claim 1, wherein the multi-dimensional feature vector being configured is based in part on one or more data points of the input GPS set. 4. The method of claim 1, wherein the attribute comprises at least one of a traffic light, a stop sign, a yield sign, a speed bump, a reduced speed zone, or mixed traffic signals. 5. The method of claim 2, wherein step (d) further comprises the sub-steps of: producing a topology from the GPS elements that pass along the segment of the driving route;drawing a rectangle to encompass at least a portion of the segment of the driving route to define a boundary; andincluding in the input GPS set the GPS data points located inside the boundary from the portions of the GPS elements that pass along the segment of the driving route. 6. The method of claim 1, wherein the multi-dimensional feature vector comprises an average value of M number of speed variables sampled from each of the GPS elements associated with the segment of the driving route. 7. The method of claim 1, wherein the multi-dimensional feature vector being configured further comprises configuring the multi-dimensional feature vector based in part on sampling a plurality of speed variables obtained from the GPS elements associated with the segment of the driving route. 8. A system for providing a prediction of a type of attribute located along a segment of a driving route based on one or more speed variation patterns obtained from Global Positioning System (GPS) elements, the system comprising: at least one processor configured to: (a) represent the segment of the driving route by a multi-dimensional feature vector capturing the one or more speed variation patterns; and(b) input the multi-dimensional feature vector into a function for the type of attribute and in response to analyzing the multi-dimensional feature vector input in the function, determining the prediction indicating whether an object of the type of attribute is physically located at the segment of the driving route. 9. The system of claim 8, wherein prior to represent the segment, the processor is further configured to: (c) retrieve a plurality of GPS elements; and(d) for each GPS element that corresponds to one or more positions along the segment of the driving route, identify a portion of the GPS element recorded along the segment of the driving route to include in an input GPS set. 10. The system of claim 8, wherein the multi-dimensional feature vector being configured is based in part on one or more data points of the input GPS set. 11.
