Embodiments of the disclosure provide systems and methods for optimizing a traffic control plan. The system may include at least one storage device configured to store instructions and at least one processor configured to execute the instructions to perform operations. The operations may include receiving traffic system log data and parsing the traffic system log data to obtain a first set of traffic performance parameters. The operations may also include receiving trajectory data relating to a plurality of vehicle movements and parsing the trajectory data to obtain a second set of traffic performance parameters. The operations may further include determining relationships between vehicle delays and degrees of saturation based on the first and second sets of traffic performance parameters. In addition, the operations may include optimizing the traffic control plan based on the relationships.

An edge device may receive, from a first device in a first vehicle moving towards an intersection, first-vehicle-provided-tracking information and, from a first sensor device at the intersection, sensor-provided-first-vehicle-tracking information. The edge device may receive, from a second device in a second vehicle moving towards the intersection, second-vehicle-provided-tracking information and, from a second sensor device at the intersection, sensor-provided-second-vehicle-tracking information. The edge device may determine whether vehicle-provided-tracking information matches the sensor-provided-tracking information for the first vehicle and/or the second vehicle. The edge device may determine whether the first vehicle and the second vehicle are predicted to collide and may provide, to one or more traffic control devices, one or more instructions to provide signals to the first vehicle and/or the second vehicle.

The present invention performs analysis more appropriately on the basis of information such as location information for a plurality of moving objects. An analysis device 30 comprises: a 311 that receives changes in location information for a plurality of vehicles 50; a storage unit 32 that stores a road on which the plurality of vehicles 50 can travel, together with link information including an intersection; a link designation unit 312 that accepts a designation of the link information to be analyzed; and a control unit 313 that differentiates between respective routes of the plurality of vehicles 50 after passage through the link corresponding to the designated link information, totals the link passage times for each route, and specifies a cause of congestion on the basis of the separation between representative values for each route, said separation being based on the results of the totaling.

Systems, methods, devices, and apparatuses for intelligent traffic signaling are disclosed. Standalone traffic signals are equipped with a plurality of sensors including RF, radar, Wi-Fi, and cellular sensors, etc., for detecting approaching automobiles in an opposing traffic lane. The traffic signal is controlled by a processor at an attached or nearby controller box, and the processor is operable to receive speed, location, and heading data directly from nearby automobiles. The processor determines, based on detected or received data corresponding to approaching automobiles, a level of safeness associated with crossing the opposing traffic lane. The level of safeness is calculated by determining an expected time to arrival of an approaching automobile at the traffic intersection, and comparing the expected time to a width of the opposing traffic lane. A light pattern at the traffic light indicates the calculated level of safeness.
