摘要： A traffic control system and a method of automatic zone creation for a smart traffic camera to be used in adaptive traffic management at an intersection are disclosed. In one aspect of the present disclosure, a method includes receiving traffic data at an intersection; creating zones at the intersection to be applied to one or more smart traffic cameras installed at the intersection; determining whether the zones are to be validated; validating the zones upon determining that the zones are to be validated; and applying the validated zones to the one or more smart traffic cameras at the intersection.

摘要： A vehicle and a traffic infrastructure device both determine their respective locations, at least one of which uses a positioning device to determine its location. At least one sends its respective location to the other, which compares the two locations, identifies a location difference, generates calibration information based on the location difference, and either calibrates the positioning device based on the calibration information or transmits the calibration information to the other device for the other device to calibrate the positioning device.

摘要： A current or forecasted weather condition at an intersection or roadway may be identified using cameras and/or other weather sensors connected with traffic infrastructure installed at the intersection or roadway. Adverse traffic events typically associated with weather conditions of the same type as the identified weather condition may be determined, for example based on historical records of correlations between weather and traffic. The traffic infrastructure may adjust an option, for example by adjusting traffic signal timings, to mitigate the adverse traffic event in response to identifying the weather condition.

摘要： Systems and methods of adaptive traffic control based on detected anomalies in traffic conditions and utilizing unmanned aerial vehicles (UAVs) to determine root causes thereof are disclosed. One aspect of the present disclosure is a method including receiving traffic data at an intersection; determining statistics associated with traffic at the intersection based on the traffic data; detecting an anomaly in the traffic based on the statistics; utilizing an unmanned aerial vehicle (UAV) to determine a root cause of the anomaly; and communicating an anomaly rule based on the root cause to a light controller to control traffic at the intersection.

摘要： A system and a method for adaptively controlling of traffic are disclosed. The method includes receiving traffic data from one or more sensors at the intersection; detecting at least one pattern in the traffic data for a given period of time; identifying at least one variable in the pattern; determining if the at least one variable is associated with one or more available traffic patterns at the intersection; based on the determining, retrieving a current traffic control program implemented at the intersection; adaptively controlling the traffic at the intersection during the given period of time by adjusting one or more parameters of the current traffic control program to yield a modified traffic control program; and storing the modified traffic control program in a database for future use.

摘要： A camera whose field of view includes an intersection of thoroughfares captures images and/or video of the intersection. Based on the captured images and/or video, a computer system surveys vehicular traffic through the intersection visible and defines both a risk zone of the intersection and a safe zone associated with the intersection. The computer system identifies that an at-risk vehicle is present in the risk zone and automatically modifying a timing of a traffic signal indicator to allow the at-risk vehicle to pass through the risk zone into the safe zone, for example by extending a green or yellow light.

摘要： The present disclosure is directed to methods and apparatus that monitor pedestrian traffic and that adjust the behavior of traffic signals at intersections and “walk”-“do not walk” indicators associated with particular crosswalks. Methods and apparatus consistent with the present disclosure may receive image or sensor data, may monitor the status of different traffic flow, and may adjust the timing of signal lights or walking indications as conditions change at an intersection. In certain instances, a traffic controller at one intersection may receive information collected by other traffic controllers along a set of streets that lead to a particular intersection. Traffic controllers that receive images of an intersection may identify partition the intersection into a set of safe and unsafe zones as those traffic controllers identify when pedestrians can safely cross an intersection.

摘要： The present disclosure is directed to methods and apparatus for providing directions to user devices that belong to pedestrians or to individuals traveling on pedestrian pathways. Pedestrians or other users of user devices wishing to travel along pedestrian pathways toward a destination may be provided instructions according to a criterion, a basic assumption, or a rule. While commonly such criteria may relate to providing individuals with directions to walk from a current location to a specified destination in a minimal time, methods and apparatus consistent with the present disclosure may also allow for a user to specify other rules or criteria that are consistent with one or more objectives or parameters specified by that user. To accomplish this, information may be received from user devices and instructions may be sent to those user devices as users of those user devices progress toward respective destinations.
