System and method of navigating vehicles
A traffic control system and a method are provided for detecting changes in traffic patterns at an intersection, establishing traffic rules therefore, and communicating the same to objects at the intersection. The method comprises receiving, by a processor, traffic data at an intersection; determining, by the processor, an average path taken by one or more objects at the intersection; determining, by the processor, a deviation of the average path from a historical average path; based on the deviation, determining by the processor, a traffic rule is to be implemented for incoming objects detected; and communicating, by the processor, the traffic rule to the incoming objects.
1. A method of traffic control, comprising:
receiving, by a processor, traffic data indicative of one or more objects moving through one or more computer-defined zones of an intersection, wherein the traffic data is obtained by tracking, using an optical sensor at the intersection, movement of points of the one or more objects;
mapping, by analyzing the traffic data with the processor, an average travel path through the one or more computer-defined zones of the intersection taken by the one or more objects at the intersection;
determining, by the processor, a deviation of the average travel path from a historical average travel path, wherein the deviation is indicative of a spatial deviation of the average travel path from the history average travel path;
based on the deviation, determining by the processor, a traffic rule is to be implemented for incoming objects, wherein the traffic rule is a function of the spatial deviation of the average travel path; and
communicating, by the processor, the traffic rule to the incoming objects.
2. The method of claim 1 , wherein the average travel path is determined over a time interval.
3. The method of claim 1 , wherein the traffic rule is to be implemented if the deviation is more than a threshold, which is indicative of a presence of an obstruction at the intersection.
4. The method of claim 1 , wherein the traffic rule indicates at least one alternative travel path to be taken by the incoming objects.
5. The method of claim 4 , wherein the at least one alternative travel path is a path, a use of which is restricted for the incoming objects absent the deviation.
6. The method of claim 5 , further comprising:
based on the deviation, determining an additional traffic rule for additional incoming objects using the at least one alternative travel path absent the deviation, the additional traffic rule directing the additional incoming objects to follow a procedure for avoiding collision with the incoming objects that are using the at least one alternative travel path due to the deviation and according to the traffic rule.
7. The method of claim 1 , further comprising:
determining if a scheduled lane closure corresponding to the intersection exists; and
upon determining that the scheduled lane closure exists, updating the traffic rule based on the scheduled lane closure.
8. A traffic controller, comprising:
memory having computer-readable instructions stored therein; and
one or more processors configured to execute the computer-readable instructions to:
receive traffic data indicative of one or more objects moving through one or more computer-defined zones of an intersection, wherein the traffic data is obtained by tracking, using an optical sensor at the intersection, movement of points of the one or more objects;
analyze the traffic data to map an average travel path through the one or more computer-defined zones of the intersection taken by the one or more objects at the intersection;
determine a deviation of the average travel path from a historical average travel path, wherein the deviation is indicative of a spatial deviation of the average travel path from the history average travel path;
based on the deviation, determine a traffic rule is to be implemented for incoming objects, wherein the traffic rule is a function of the spatial deviation of the average travel path; and
communicate the traffic rule to the incoming objects.
9. The traffic controller of claim 8 , wherein the one or more processors are configured to execute the computer-readable instructions to:
retrieve historical traffic data from a traffic database; and
determine the historical average travel path based on the historical traffic data retrieved from the traffic data base.
10. The traffic controller of claim 9 , wherein
the average travel path is determined over a first time interval and the historical average travel path is determined over a second time interval, and
the second time interval has a longer duration than the first time interval.
11. The traffic controller of claim 8 , wherein the traffic rule is to be implemented if the deviation is more than a threshold, which is indicative of a presence of an obstruction at the intersection.
12. The traffic controller of claim 8 , wherein:
the traffic rule indicates at least one alternative travel path to be taken by the incoming objects, and
the at least one alternative travel path is a path, a use of which is restricted for the incoming objects absent the deviation.
13. The traffic controller of claim 12 , wherein the one or more processors are configured to execute the computer-readable instructions to:
based on the deviation, determine an additional traffic rule for additional incoming objects using the at least one alternative travel path absent the deviation, the additional traffic rule directing the additional incoming objects to follow a procedure for avoiding collision with the incoming objects that are using the at least one alternative travel path due to the deviation and according to the traffic rule.
14. One or more non-transitory computer-readable medium having computer-readable instructions stored therein, which when executed by one or more processors, cause the one or more processors to:
receive traffic data indicative of one or more objects moving through one or more computer-defined zones of an intersection, wherein the traffic data is obtained by tracking, using an optical sensor at the intersection, movement of points of the one or more objects;
analyze the traffic data to map an average travel path through the one or more computer-defined zones of the intersection taken by the one or more objects at the intersection;
determine a deviation of the average travel path from a historical average travel path, wherein the deviation is indicative of a spatial deviation of the average travel path from the history average travel path;
based on the deviation, determine a traffic rule is to be implemented for incoming objects, wherein the traffic rule is a function of the spatial deviation of the average travel path; and
communicate the traffic rule to the incoming objects.
15. The one or more non-transitory computer-readable medium of claim 14 , wherein the execution of the computer-readable instructions by the one or more processors, cause the one or more processors to:
retrieve historical traffic data from a traffic database; and
determine the historical average travel path based on the historical traffic data retrieved from the traffic data base.
16. The one or more non-transitory computer-readable medium of claim 15 , wherein
the average travel path is determined over a first time interval and the historical average travel path is determined over a second time interval, and
the second time interval has a longer duration than the first time interval.
17. The one or more non-transitory computer-readable medium of claim 14 , wherein the traffic rule is to be implemented if the deviation is more than a threshold, which is indicative of a presence of an obstruction.
18. The one or more non-transitory computer-readable medium of claim 14 , wherein:
