Claim 0:
1. An apparatus comprising at least one processor and at least one non-transitory memory including computer program code instructions, the computer program code instructions configured to, when executed, cause the apparatus to:
collect first sound data captured by a sound capturing device at or proximate to a road segment;
determine whether the first sound data correspond to a sound type associated with a database including a map layer;
responsive to the first sound data corresponding to the sound type, generate a first data point for the map layer, wherein the first data point associates the sound type to the road segment;
responsive to the first sound data not corresponding to the sound type or any other sound types stored in the database, collect second sound data captured by other sound capturing devices within a predetermined distance from a location at which the sound capturing device captured the first sound data;
determine whether the second sound data corresponds to the sound type or one of any other sound types stored in the database;
responsive to the second sound data corresponding to the sound type or the one of any other sound types stored in the database:
classify the first sound data as corresponding to the sound type or the one of any other sound types stored in the database;
generate the first data point or a second data point, wherein the second data point associates the one of any other sound types to the road segment;

store the first data point or the second data point in the database, wherein the map layer comprises: (i) the first data point or the second data point; and (ii) one or more other data points that associate the sound type or one or more other sound types to one or more other road segments;
receive a user preference indicating the sound type;
identify the road segment associated with the sound type from a plurality of road segments within the map layer;
select a subset from the plurality of road segments as a route based on association of the subset with respect to the road segment; and
cause a user interface to output the route.
