A navigation system for collecting anonymized drive information relative to a road section traversed by a host vehicle, the navigation system located in the host vehicle, the navigation system comprising: at least one processor programmed to: receive, from one or more sensors (122, 2315, 2320, 2325, 2330), outputs indicative of motion of the host vehicle; determine at least one motion representation for the host vehicle based, at least in part, on the outputs from the one or more sensors; receive, from a camera (122, 124, 126), at least one image representative of an environment of the host vehicle along the road section; analyze the at least one image to determine at least one road characteristic associated with the road section; assemble first road segment information relative to a first portion of the road section, wherein the first road segment information includes the determined at least one motion representation for the host vehicle and the determined at least one road characteristic relative to the first portion of the road section; assemble second road segment information relative to a second portion of the road section, wherein the second road segment information includes the determined at least one motion representation for the host vehicle and the determined at least one road characteristic relative to the second portion of the road section, and wherein the second portion of the road section is different from the first portion of the road section and is spatially separated from the first portion of the road section by a third portion of the road section, wherein if the at least one road characteristic associated with the road section includes a unique road characteristic, at least one of the first portion of the road section or the second portion of the road section is designated by the at least one processor such that the unique road characteristic is fully included within either the first road segment information or the second road segment information; cause transmission of the first road segment information and the second road segment information from the host vehicle to a server remotely located relative to the host vehicle for assembly of an autonomous vehicle road navigation model; and forgo transmission to the server of assembled road segment information relating to the third portion of the road section. receive, from one or more sensors (122, 2315, 2320, 2325, 2330), outputs indicative of motion of the host vehicle; determine at least one motion representation for the host vehicle based, at least in part, on the outputs from the one or more sensors; receive, from a camera (122, 124, 126), at least one image representative of an environment of the host vehicle along the road section; analyze the at least one image to determine at least one road characteristic associated with the road section; assemble first road segment information relative to a first portion of the road section, wherein the first road segment information includes the determined at least one motion representation for the host vehicle and the determined at least one road characteristic relative to the first portion of the road section; assemble second road segment information relative to a second portion of the road section, wherein the second road segment information includes the determined at least one motion representation for the host vehicle and the determined at least one road characteristic relative to the second portion of the road section, and wherein the second portion of the road section is different from the first portion of the road section and is spatially separated from the first portion of the road section by a third portion of the road section, wherein if the at least one road characteristic associated with the road section includes a unique road characteristic, at least one of the first portion of the road section or the second portion of the road section is designated by the at least one processor such that the unique road characteristic is fully included within either the first road segment information or the second road segment information; cause transmission of the first road segment information and the second road segment information from the host vehicle to a server remotely located relative to the host vehicle for assembly of an autonomous vehicle road navigation model; and forgo transmission to the server of assembled road segment information relating to the third portion of the road section.
