Abstract
Systems, methods, and apparatuses are disclosed for predicting or estimating the value of a variable speed sign (VSS). A variable speed sign is identified. Probe data is collected at one or more vehicles in proximity to the variable speed sign. The speeds of the vehicles are included in or derived from the probe data. A statistical analysis is performed on the probe data. A speed limit value for the variable speed sign is determined based on the statistical analysis.
Claims20
A method comprising:
- identifying a variable speed sign;
- receiving probe data collected at a plurality of vehicles in proximity to the variable speed sign, wherein the probe data includes speeds of the plurality of vehicles;
- performing a statistical analysis on the probe data;
- and
- determining, using the processor, a speed limit value for the variable speed sign based on the statistical analysis.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs;
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least perform:
- identifying a variable speed sign;
- receiving probe data collected at a plurality of vehicles downstream of the variable speed sign, wherein the probe data includes speeds of the plurality of vehicles and locations of the plurality of vehicles;
- performing a statistical analysis on the probe data;
- and
- selecting, using the processor, a speed limit value for the variable speed sign based on the statistical analysis.
A non-transitory computer readable medium including instructions that when executed on a computer are operable to:
- collect probe data including geographic locations;
- send the probe data including geographic locations to an external device, wherein a variable speed sign is identified from the geographic locations and a vehicle speed is derived from the probe data;
- receive a speed limit value for the variable speed sign based on a statistical analysis of the probe data, wherein the statistical analysis includes clustering;
- and
- provide the speed limit value to a mobile device or a vehicle associated with the mobile device.
