Methods of providing traffic flow messages
First Claim
1. A method of improving a message indicative of an event affecting traffic flow on at least a portion of one or more navigable segments, the method comprising:
- obtaining a message with associated location information indicative of a location of an event affecting traffic flow;
using the location information to identify an initial navigable stretch comprising at least a portion of one or more navigable segments on which traffic flow is considered to be affected by the event;
obtaining positional data relating to the movement of a plurality of devices along a navigable stretch selected using the location information, wherein the navigable stretch includes at least the initial navigable stretch;
using the positional data to obtain speed data indicative of a speed of travel of the devices at a plurality of positions along the navigable stretch;
using the speed data to identify an actually affected navigable stretch comprising at least a portion of one or more navigable segments that is actually affected by the event; and
modifying the message, or generating a new message indicative of the event, so as to include location information indicative of the actually affected navigable stretch.

Abstract
A method of verifying and/or improving a message indicative of an event affecting traffic flow on at least a portion of one or more navigable segments is described. The method involves obtaining positional data relating to the movement of a plurality of devices along a navigable stretch including a navigable stretch identified by the message as being affected, and using the positional data to verify and/or improve the message. The positional data is live data and is used to obtain data relating to the speed of travel of the devices along the navigable stretch including the stretch identified by the message. The speed data can be used to determine a spatial extent of the affected stretch and/or an expected speed of travel along the stretch.

18. A non-transitory computer readable medium comprising computer readable instructions, which, when executed on a computer, cause the computer to perform a method for improving a message indicative of an event affecting traffic flow on at least a portion of one or more navigable segments, the method comprising:
-
obtaining a message with associated location information indicative of a location of an event affecting traffic flow; using the location information to identify an initial navigable stretch comprising at least a portion of one or more navigable segments on which traffic flow is considered to be affected by the event; obtaining positional data relating to the movement of a plurality of devices along a navigable stretch selected using the location information, wherein the navigable stretch includes at least the initial navigable stretch; using the positional data to obtain speed data indicative of a speed of travel of the devices at a plurality of positions along the navigable stretch; using the speed data to identify an actually affected navigable stretch comprising at least a portion of one or more navigable segments that is actually affected by the event; and modifying the message, or generating a new message indicative of the event, so as to include location information indicative of the actually affected navigable stretch.

19. A system for verifying and/or improving a message indicative of an event affecting traffic flow on at least a portion of one or more navigable segments, the system comprising:
-
one or more processors; and a memory comprising instructions which, when executed by the one or more processors, cause the system to; obtain a message with associated location information indicative of a location of an event affecting traffic flow; use the location information to identify an initial navigable stretch comprising at least a portion of one or more navigable segments on which traffic flow is considered to be affected by the event; obtain positional data relating to the movement of a plurality of devices along a navigable stretch selected using the location information, wherein the navigable stretch includes at least the initial navigable stretch; use the positional data to obtain speed data indicative of a speed of travel of the devices at a plurality of positions along the navigable stretch; use the speed data to identify an actually affected navigable stretch comprising at least a portion of one or more navigable segments that is actually affected by the event; and modify the message, or generate a new message indicative of the event, so as to include location information indicative of the actually affected navigable stretch.
