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.

First claim

1 . A method comprising:
determining signage information associated with at least one location; 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; and 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.

2 . A method of claim 1 , wherein the signage information includes, at least in part, 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.

3 . A method of claim 2 , 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, one or more traffic signs, one or more non-traffic signs, or a combination thereof.

4 . A method of claim 1 , wherein the one or more attributes associated with the at least one location includes, at least in part, a traffic volume attribute.

5 . A method of claim 4 , further comprising:
causing, at least in part, a use of normalized probe density data as a proxy for the traffic volume attribute.

6 . A method of claim 1 , further comprising:
determining historical safety information for the at least one location, wherein the historical safety information includes, at least in part, historical accident information for the at least one location; and causing, at least in part, a training of the at least one predictor model based, at least in part, on the historical safety information.

7 . A method of claim 6 , further comprising:
causing, at least in part, a labeling of the at least one location according to the one or more safety levels using the historical safety information, wherein the training of the at least one predictor model is based, at least in part, on the labeling.

8 . A method of claim 7 , further comprising:
processing and/or facilitating a processing of the historical safety information to determine a number of accidents, a number of accidents per length of road segment, a number of accidents per unit of time, or a combination thereof, wherein the labeling of the at least one location is based, at least in part, on the number of accidents, the number of accidents per length of road segment, the number of accidents per unit of time, or a combination thereof.

9 . A method of claim 1 , further comprising at least one of the following:
causing, at least in part, a ranking of the at least one location, the one or more other locations, or a combination thereof based, at least in part, on the one or more safety levels; causing, at least in part, a presentation of at least one map encompassing the at least one location, the one or more other locations, or a combination thereof that is coded to show the one or more safety levels; causing, at least in part, a presentation of one or more notifications based, at least in part, on the one or more safety levels; and causing, at least in part, a calculation of at least one navigation route to avoid one or more areas based, at least in part, on the one or more safety levels.

10 . A method of claim 1 , wherein (a) the creation of the at least one predictor model; (b) the classification of the at least one location, one or more other locations, or a combination thereof; or (c) a combination thereof is performed with respect to an individual user, a group of users, or a combination thereof.

11 . A method of claim 1 , wherein the signage information includes, at least in part, an absence of the one or more signs in the at least one location, a detectability of the one or more signs, or a combination thereof.

12 . 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,
determine signage information associated with at least one location;
cause, 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; and
cause, 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.

13 . An apparatus of claim 12 , wherein the signage information includes, at least in part, 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.

14 . An apparatus of claim 13 , 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, one or more traffic signs, one or more non-traffic signs, or a combination thereof.

15 . An apparatus of claim 12 , wherein the one or more attributes associated with the at least one location includes, at least in part, a traffic volume attribute.

16 . An apparatus of claim 15 , wherein the apparatus is further caused to:
cause, at least in part, a use of normalized probe density data as a proxy for the traffic volume attribute.

17 . An apparatus of claim 12 , wherein the apparatus is further caused to:
determine historical safety information for the at least one location, wherein the historical safety information includes, at least in part, historical accident information for the at least one location; and cause, at least in part, a training of the at least one predictor model based, at least in part, on the historical safety information.

18 . An apparatus of claim 17 , wherein the apparatus is further caused to:
cause, at least in part, a labeling of the at least one location according to the one or more safety levels using the historical safety information, wherein the training of the at least one predictor model is based, at least in part, on the labeling.

19 . A 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:
determining signage information associated with at least one location; 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; and 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.

20 . A computer-readable storage medium of claim 19 , wherein the signage information includes, at least in part, 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.
