Generation in a mobile device of a traffic map based on traffic messages
A Global Positioning System (GPS) enabled mobile device includes traffic map generation capability. The mobile device receives traffic messages including information about a traffic event. Based on the information included in the traffic messages and a current location, the mobile device generates a traffic map depicting a location of the traffic event and the current location.
1 . A system comprising:
a global positioning system module configured to determine a current location;
a traffic message receiver configured to receive traffic messages each comprising an event code and a location code;
a traffic module configured to identify a traffic message of the traffic messages having an event location within a predetermined distance of the current location based on the location code of the traffic message; and
a map module configured to generate a traffic map of an area comprising the current location and the event location of the identified traffic message, the traffic map comprising an event graphic corresponding to the event code of the identified traffic message, the event graphic placed on the traffic map according to the event location of the identified traffic message.
2 . The system of claim 1 , wherein the traffic module is configured to store the traffic messages in a traffic message inbox.
3 . The system of claim 1 , wherein the traffic messages are in accordance with a standard.
4 . The system of claim 1 , wherein the predetermined distance is based on a zoom level of the traffic map.
5 . The system of claim 1 , wherein the predetermined distance is received from a user.
6 . The system of claim 1 , wherein the event graphic is color-coded based on a severity of the event code of the identified traffic message.
7 . The system of claim 1 , wherein the event location is a point location on a road.
8 . The system of claim 1 , wherein the event location is a segment of a road.
9 . The system of claim 1 , wherein the map module is configured to generate the traffic map on a periodic basis.
10 . The system of claim 1 , wherein the map module is configured to update the traffic map.
11 . The system of claim 1 , wherein the map module is configured to generate the traffic map by adding the event graphic to a road map.
12 . The system of claim 1 , wherein the map module is configured to generate the traffic map based on a road map and the identified traffic message.
13 . The system of claim 1 , wherein the map module is configured to generate the traffic map based on a zoom level received from a user.
14 . A method comprising:
determining a current location of a mobile device;
receiving, at the mobile device, traffic messages each comprising an event code and a location code;
identifying a traffic message of the traffic messages having an event location within a predetermined distance of the current location based on the location code of the traffic message; and
generating a traffic map of an area comprising the current location and the event location of the identified traffic message, the traffic map comprising an event graphic corresponding to the event code of the identified traffic message, the event graphic placed on the traffic map according to the event location of the identified traffic message.
15 . The method of claim 14 , further comprising storing the received traffic message in a traffic message inbox.
16 . The method of claim 14 , wherein the traffic messages are in accordance with a standard.
17 . The method of claim 14 , further comprising:
identifying an other traffic message having an other event location within the predetermined distance of the current location based on an other location code of the traffic message; and
generating an other traffic map of the area comprising the current location and the event location of the other identified traffic message, the other traffic map comprising an other event graphic corresponding to an other event code of the other identified traffic message, the other event graphic placed on the other traffic map according to the other event location of the other identified traffic message.
18 . The method of claim 14 , further comprising,
identifying an other traffic message having an other event location within the predetermined distance of the current location based on the other location code of the other traffic message; and
updating the traffic map of the area comprising the current location and the event location of the identified traffic message, the updated traffic map comprising an other event graphic corresponding to the other event code of the other identified traffic message, the other event graphic placed on the traffic map according to the other event location of the other identified traffic message.
19 . The method of claim 14 , wherein the pre-determined distance is based on a zoom-level of the traffic map.
20 . A computer readable medium having embodied thereon instructions executable by a
processor for performing a method for generating a traffic map, the method comprising:
determining a current location of a mobile device;
receiving, at the mobile device, traffic messages each comprising an event code and a location code;
identifying a traffic message of the traffic messages having an event location within a predetermined distance of the current location based on the location code of the traffic message; and
generating a traffic map of an area comprising the current location and the event location of the identified traffic message, the traffic map comprising an event graphic corresponding to the event code of the identified traffic message, the event graphic placed on the traffic map according to the event location of the identified traffic message.
