1. A method comprising:
- acquiring signage information, by way of at least one sensor and at least one of the following;
a map, a database and cloud, the signage information associated with at least one location, the signage information including a presence of one or more signs in the at least one location, one or more characteristics of the one or more signs, one or more locations of the one or more signs, or a combination thereof, and wherein the one or more signs include, at least in part, one or more physical signs, one or more virtual signs, or a combination thereof, and wherein the one or more signs include, at least in part, a combination of one or more traffic signs and one or more non-traffic signs;
creating at least one predictor model based, at least in part, on the signage information and one or more attributes associated with the at least one location, wherein the one or more attributes associated with the at least one location include, at least in part, a traffic volume attribute;
classifying the at least one location, one or more other locations, or a combination thereof according to one or more safety levels using, at least in part, the at least one predictor model; and
using normalized probe density data as a proxy for the traffic volume attribute,wherein the normalized probe density data is derived from probe data that has been filtered, the probe data includes more than one of historical safety information, speed information, and timestamp information, for one or more vehicles in at least one road link associated with the at least one location, andwherein the filtered probe data has been map-matched with historical accident data.

Abstract
An approach is provided for determining safety levels for one or more locations based, at least in part, on signage information. The approach involves determining signage information associated with at least one location. The approach also involves causing, at least in part, a creation of at least one predictor model based, at least in part, on the signage information and one or more attributes associated with the at least one location. The approach also involves causing, at least in part, a classification of the at least one location, one or more other locations, or a combination thereof according to one or more safety levels using, at least in part, the at least one predictor model.

8. 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 perform at least the following, acquiring signage information, by way of at least one sensor and at least one of the following;
a map, a database and cloud, the signage information associated with at least one location and the signage information including a presence of one or more signs in the at least one location, one or more characteristics of the one or more signs, one or more locations of the one or more signs, or a combination thereof, and wherein the one or more signs include, at least in part, a combination of one or more traffic signs and one or more non-traffic signs;creating at least one predictor model based, at least in part, on the signage information and one or more attributes associated with the at least one location, wherein the one or more attributes associated with the at least one location include, at least in part, a traffic volume attribute; classifying the at least one location, one or more other locations, or a combination thereof according to one or more safety levels using, at least in part, the at least one predictor model; and using normalized probe density data as a proxy for the traffic volume attribute, wherein the normalized probe density data is derived from probe data that has been filtered, the probe data includes more than one of historical safety information, speed information, and timestamp information, for one or more vehicles in at least one road link associated with the at least one location, and wherein the filtered probe data has been map-matched with historical accident data. - View Dependent Claims (9, 10, 11)

12. A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to at least perform the following steps:
-
acquiring signage information, by way of at least one sensor and at least one of the following;
a map, a database and cloud, the signage information associated with at least one location and the signage information including a presence of one or more signs in the at least one location, one or more characteristics of the one or more signs, one or more locations of the one or more signs, or a combination thereof, and wherein the one or more signs include, at least in part, a combination of one or more traffic signs and one or more non-traffic signs;creating at least one predictor model based, at least in part, on the signage information and one or more attributes associated with the at least one location, wherein the one or more attributes associated with the at least one location include, at least in part, a traffic volume attribute; classifying the at least one location, one or more other locations, or a combination thereof according to one or more safety levels using, at least in part, the at least one predictor model; and using normalized probe density data as a proxy for the traffic volume attribute, wherein the normalized probe density data is derived from probe data that has been filtered, the probe data includes more than one of historical safety information, speed information, and timestamp information, for one or more vehicles in at least one road link associated with the at least one location, and wherein the filtered probe data has been map-matched with historical accident data.
