The method also comprises the navigation apparatus generating a message in response to detection of a profile associated with speed of the navigation apparatus and that corresponds to a predetermined speed change profile associated with the presence of the temporarily located road feature. ## Claims ### Claim 1 A navigation apparatus comprising: a location determining unit for determining a location of the apparatus; and one or more processors configured to monitor a speed of the apparatus, or a parameter associated therewith; wherein, when in use, the apparatus is arranged to: detect the location of a temporarily-located road feature by detection of a speed profile of the apparatus corresponding to a predetermined speed change profile; generate a message comprising data indicative of the location at which the speed profile was detected; prompt a user of the navigation apparatus for a confirmatory input in response to the detection; upon receipt of the confirmatory input, generate confirmatory data; and transmit the message to a remote data processing resource to update a listing of known feature locations. ### Claim 2 (depends on 1) An apparatus as claimed in claim 1, wherein the predetermined speed change profile is substantially U-shaped. ### Claim 3 (depends on 1) An apparatus as claimed in claim 1, wherein the predetermined speed change profile comprises a first portion corresponding to a reduction in speed. ### Claim 4 (depends on 3) An apparatus as claimed in claim 3, wherein the predetermined speed change profile comprises a second portion corresponding to maintaining speed substantially below or substantially equal to a speed limit. ### Claim 5 (depends on 3) An apparatus as claimed in claim 3, wherein the maintenance of the speed is for a minimum predetermined duration. ### Claim 6 (depends on 4) An apparatus as claimed in claim 4, wherein the predetermined speed change profile comprises a third portion corresponding to an increase in speed. ### Claim 7 (depends on 6) An apparatus as claimed in claim 6, wherein the third portion follows the second portion. ### Claim 8 (depends on 4) An apparatus as claimed in claim 4 wherein the second portion follows the first portion. ### Claim 9 (depends on 1) An apparatus as claimed in claim 1 wherein the prompt for confirmatory input comprises one of; a telephone call to the user, a text message or a prompt via the user interface of the navigation apparatus. ### Claim 10 (depends on 1) An apparatus as claimed in claim 1, configured to receive the confirmatory input via a hardware or software button on the navigation apparatus, or via voice input. ### Claim 11 (depends on 1) An apparatus as claimed in claim 1, further configured to transmit the message to a remote processing device. ### Claim 12 (depends on 11) An apparatus as claimed in claim 11, wherein the message further comprises the confirmatory data. ### Claim 13 (depends on 1) An apparatus as claimed in claim 1, wherein the apparatus is arranged to perform pattern recognition by comparing the speed profile of the apparatus with the predetermined speed change profile to determine a vehicular speed change behavior indicative of a temporarily located road feature. ### Claim 14 (depends on 1) An apparatus as claimed in claim 1, wherein the message comprises at least one of: data identifying at least one of a plurality of message types, location data and supporting data. ### Claim 15 A method of identifying a temporarily located road feature that engenders vehicular speed behaviour change, the method comprising: providing a navigation apparatus comprising: a location determining unit for determining a location of the apparatus; and one or more processors configured to monitor a speed of the apparatus, or a parameter associated therewith; detecting the location of a temporarily-located road feature by detection of a speed profile of the apparatus corresponding to a predetermined speed change profile; generating a message comprising data indicative of the location at which the speed profile was detected; prompting a user of the navigation apparatus for a confirmatory input in response to the detection; upon receipt of the confirmatory input, generating confirmatory data; and transmit the message to a remote data processing resource to update a listing of known feature locations. ### Claim 16 A non-transitory computer-readable medium which stores a set of instructions which when executed performs a method of identifying a temporarily located road feature that engenders vehicular speed behaviour change, the method executed by the set of instructions comprising: providing a navigation apparatus comprising: a location determining unit for determining a location of the apparatus; and one or more processors configured to monitor a speed of the apparatus, or a parameter associated therewith; detecting the location of a temporarily-located road feature by detection of a speed profile of the apparatus corresponding to a predetermined speed change profile; generating a message comprising data indicative of the location at which the speed profile was detected; prompting a user of the navigation apparatus for a confirmatory input in response to the detection; upon receipt of the confirmatory input, generating confirmatory data; and transmit the message to a remote data processing resource to update a listing of known feature locations.
