Adaptive optimization of navigational routes using traffic data
A traffic control system and a method for optimizing navigational routing based on per-intersection real-time traffic conditions data. One aspect is a method of providing navigational guidance. The method includes identifying at least one intersection along at least one initial route to a destination; modifying the at least one initial route based on user preferences and traffic conditions data associated with the at least one intersection to yield at least one modified route; receiving a selection of a route from among the at least one modified route; receiving updated traffic conditions data for at least one corresponding intersection along the route selected; and modifying the route selected based on the updated traffic conditions data.
1. A method of providing navigation guidance, the method comprising:
identifying at least one intersection along at least one initial route to a destination;
modifying the at least one initial route based on user preferences and traffic conditions data associated with the at least one intersection to yield at least one modified route, wherein:
the user preferences comprise pedestrian count; and
the traffic conditions data comprises data captured by a traffic sensor positioned at the at least one intersection;
receiving a selection of a route from among the at least one modified route;
receiving updated traffic conditions data for at least one corresponding intersection along the route selected including real-time pedestrian count; and
modifying the route selected, based on the updated traffic conditions data and user preferences that comprise pedestrian count,
wherein modifying the at least one initial route includes excluding at least one route upon determining that corresponding traffic conditions data for at least one intersection along the at least one route does not match one of the user preferences, and
wherein the traffic conditions data and the updated traffic conditions data include a per-zone pedestrian count for the corresponding intersection.
2. The method of claim 1 , further comprising:
receiving a request for a route to the destination; and
determining the at least one initial route based on the request.
3. The method of claim 2 , wherein determining the at least one initial route is based on data retrieved from a navigation database and the user preferences.
4. The method of claim 1 , wherein modifying the at least one initial route includes excluding at least one route upon determining that corresponding traffic conditions data for at least one intersection along the at least one route does not match one of the user preferences.
5. The method of claim 1 , wherein modifying the route selected comprises: modifying the route selected prior to arrival of an object at the at least one corresponding intersection.
6. The method of claim 1 , wherein the traffic conditions data and the updated traffic conditions data include at least one of an average traffic flow rate at a corresponding intersection, a per-zone traffic flow rate at the corresponding intersection, an average pedestrian count for the corresponding intersection, and a current per-zone traffic signal duration at the corresponding intersection.
7. The method of claim 1 , wherein the updated traffic conditions data is received periodically after the route is selected.
8. A device configured to provide navigation guidance, the device comprising:
memory having computer-readable instructions stored therein; and
one or more processors configured to execute the computer-readable instructions to:
identify at least one intersection along at least one initial route to a destination;
modify the at least one initial route based on user preferences and traffic conditions data associated with the at least one intersection to yield at least one modified route, wherein:
the user preferences comprise pedestrian count; and
the traffic conditions data comprises data captured by a traffic sensor positioned at the at least one intersection;
receive a selection of a route from among the at least one modified route;
receive updated traffic conditions data for at least one corresponding intersection along the route selected including real-time pedestrian count; and
modify the route selected based on the updated traffic conditions data and user preferences that comprise pedestrian count,
wherein modification of the at least one initial route includes excluding at least one route upon determining that corresponding traffic conditions data for at least one intersection along the at least one route does not match one of the user preferences, and
wherein the traffic conditions data and the updated traffic conditions data include a per-zone pedestrian count for the corresponding intersection.
9. The device of claim 8 , wherein the one or more processors are configured to execute the computer-readable instructions to: receive a request for a route to the destination; and
determine the at least one initial route based on the request.
10. The device of claim 9 , wherein the one or more processors are configured to execute the computer-readable instructions to determine the at least one initial route is based on data retrieved from a navigation database and the user preferences.
11. The device of claim 8 , wherein the one or more processors are configured to execute the computer-readable instructions to modify the route selected prior to arrival of an object at the at least one corresponding intersection.
12. The device of claim 8 , wherein the traffic conditions data and the updated traffic conditions data include at least one of an average traffic flow rate at a corresponding intersection, a per-zone traffic flow rate at the corresponding intersection, an average pedestrian count for the corresponding intersection, and a current per-zone traffic signal duration at the corresponding intersection.
13. The device of claim 8 , wherein the updated traffic conditions data is received periodically after the route is selected.
14. One or more computer-readable medium having computer-readable instructions stored therein, which when executed by one or more processors, cause the one or more processors to:
identify at least one intersection along at least one initial route to a destination;
modify the at least one initial route based on user preferences and traffic conditions data associated with the at least one intersection to yield at least one modified route, wherein:
the user preferences comprise pedestrian count; and
the traffic conditions data comprises data captured by a traffic sensor positioned at the at least one intersection;
receive a selection of a route from among the at least one modified route;
receive updated traffic conditions data for at least one corresponding intersection along the route selected including real-time pedestrian count; and
modify the route selected based on the updated traffic conditions data and user preferences that comprise pedestrian count,
wherein modification of the at least one initial route includes excluding at least one route upon determining that corresponding traffic conditions data for at least one intersection along the at least one route does not match one of the user preferences, and
wherein the traffic conditions data and the updated traffic conditions data include a per-zone pedestrian count for the corresponding intersection.
15. The one or more computer-readable medium of claim 14 , wherein the execution of the computer-readable instructions cause the one or more processors to: receive a request for a route to the destination; and determine the at least one initial route based on the request.
16. The one or more computer-readable medium of claim 15 , wherein the execution of the computer-readable instructions cause the one or more processors to determine the at least one initial route is based on data retrieved from a navigation database and the user preferences.
17. The one or more computer-readable medium of claim 14 , wherein the execution of the computer-readable instructions cause the one or more processors to modify the route selected prior to arrival of an object at the at least one corresponding intersection.
18. The one or more computer-readable medium of claim 14 , wherein the traffic conditions data and the updated traffic conditions data include at least one of an average traffic flow rate at a corresponding intersection, a per-zone traffic flow rate at the corresponding intersection, an average pedestrian count for the corresponding intersection, and a current per-zone traffic signal duration at the corresponding intersection.
