System and method for realtime community information exchange
System and method for traffic mapping service are disclosed for allowing plurality of users having each a navigation device to transmit their locations to a server and optionally to signal to the server their requested destination. The system and method are further capable of calculating traffic parameters such as current traffic speed at a given road based on the momentary locations of the users. The system and method of the invention may also calculate and advise the users of preferred roads to take in order to arrive at the requested location with minimum delay.
1 . A navigation system comprising:
a server configured to:
receive location information from a set of navigation devices, each navigation device of the set of navigation devices being associated with a member of a navigation service, wherein the location information comprises a current location of the respective navigation device;

receive, from the first navigation device, an indication of at least one parameter associated with the location information, the at least one parameter including a route preference;
select a subset of navigation devices from the set of navigation devices based on the destination of the first navigation device and the at least one parameter, the subset including a plurality of navigation devices and excluding navigation devices that do not meet the at least one parameter;
continuously update the location information from the navigation devices in the subset;
generate a dynamic representation of real-time traffic data based on at least the continuously updated location information received from the subset of navigation devices; and
send the dynamic representation to the first navigation device.

3 . The system of claim 2 , wherein the server is further configured to select the subset of navigation devices further based on the location information received from the subset of navigation devices.
4 . The system of claim 2 , wherein the server is further configured to select the subset of navigation devices further based on comparison between the location information received from the subset of navigation devices and the route.
5 . The system of claim 1 , wherein the server is further configured to select the subset of navigation devices further based on a type of mobility for any members associated with the subset of navigation devices.
6 . The system of claim 1 , wherein the server is further configured to select the subset of navigation devices further based on a type of mobility for the member associated with the first navigation device.
7 . The system of claim 1 , wherein the server is further configured to:
as the location information received from the set of navigation devices changes over time, update the subset of navigation devices by adding new navigation devices to the subset of navigation devices and/or removing navigation devices from the subset of navigation devices.
8 . The system of claim 1 , wherein the server is further configured to identify a destination for each navigation device of the set of navigation devices and wherein the subset of navigation devices is further selected based on the destinations of the set of navigation devices.
9 . The system of claim 1 , wherein the location information received from the set of navigation devices identifies a last current location reported to the server and the server is further configured to select the subset of navigation devices based on a distance between the last current locations reported of the set of navigation devices and the last current location reported of the first navigation device.
10 . The system of claim 1 , wherein the server is further configured to:
calculate a route to the destination based on the continuously updated location information; and
send the route to the first device.
11 . A method comprising:
receiving, by a server, location information from a set of navigation devices each navigation device of the set of navigation devices being associated with a member of a navigation service, wherein the location information comprises a current location of the respective navigation device;
identifying, by the server, a destination for a first navigation device of the set of navigation devices, wherein the destination comprises a geographical place to which the first navigation device is traveling;
receiving, from the first navigation device, an indication of at least one parameter associated with the location information, the at least one parameter including a route preference;
selecting, by the server, a subset of navigation devices from the set of navigation devices based on the destination of the first navigation device and the at least one parameter, the subset including a plurality of navigation devices and excluding navigation devices that do not meet the at least one parameter;
continuously updating, by the server, the location information from the navigation devices in the subset;
generating, by the server, a dynamic representation of real-time traffic data based on at least the continuously updating location information received from the subset of navigation devices; and
sending, by the server, the dynamic representation to the first navigation device.
12 . The method of claim 11 , further comprising determining a route to the destination of the first navigation device using the location information received from the first navigation device, and wherein selecting the subset of navigation devices is further based on the route.
13 . The method of claim 12 , wherein selecting the subset of navigation devices is further based on the location information received from the subset of navigation devices.
14 . The method of claim 12 , wherein selecting the subset of navigation devices is further based on comparison between the location information received from the subset of navigation devices and the route.
15 . The method of claim 11 , wherein selecting the subset of navigation devices is further based on a type of mobility for any members associated with the subset of navigation devices.
16 . The method of claim 11 , wherein selecting the subset of navigation devices is further based on a type of mobility for the member associated with the first navigation device.
17 . The method of claim 11 , further comprising:
as the location information received from the set of navigation devices changes over time, updating the subset of navigation devices by adding and/or removing navigation devices from the subset of navigation devices.
18 . The method of claim 11 , further comprising:
calculating, by the server, a route to the destination based on the continuously updated location information; and
sending the route to the first device.
19 . A non-transitory computer-readable medium storing instructions executable by one or more processors for performing a method, comprising:
receiving location information from a set of navigation devices, each navigation device of the set of navigation devices being associated with a member of a navigation service, wherein the location information comprises a current location of the respective navigation device;
identifying a destination for a first navigation device of the set of navigation devices, wherein the destination comprises a geographical place to which the first navigation device is traveling;
receiving, from the first navigation device, an indication of at least one parameter associated with the location information, the at least one parameter including a route preference;
selecting a subset of navigation devices from the set of navigation devices based on the destination of the first navigation device and the at least one parameter, the subset including a plurality of navigation devices and excluding navigation devices that do not meet the at least one parameter;
