Abstract: A traffic signal control apparatus comprises a determination part determining whether or not to stop the vehicle based on behavior of the vehicle entering a predetermined intersection; and a selection part selecting a traffic signal machine(s) that performs signal control for stopping the vehicle from among control target traffic signal machines. The selection part selects a traffic signal machine(s) that is located in a traveling direction of the vehicle and that may eliminate traffic jam by the signal control for stopping the vehicle.

Abstract: A method of controlling a traffic system having a plurality of intersections with switchable traffic lights and road sections located between the intersections includes detecting traffic loads of multiple relevant road sections, determining a local stress function for each relevant road section depending on the detected traffic load of the respective relevant road section, determining a global stress function for the entire traffic system based on the local stress functions, determining, using a quantum concept processor, improved switching times for the traffic lights of the intersections adjacent to the relevant road sections, wherein the improved switching times are determined such that the global stress function reaches a smallest detectable value, and switching the traffic lights according to a switching model based on the improved switching times.

Abstract: A traffic light control system includes a first traffic light apparatus and multiple second traffic light apparatuses for displaying a direction pattern indicating intended movement of an emergency vehicle about to pass through an intersection, and a controller storing direction patterns each indicating a direction to take and a specific movement manner of the emergency vehicle. In response to a direction signal corresponding to one of the direction patterns, the controller controls the first traffic light apparatus to display the one direction pattern, and controls each of the second traffic light apparatuses to display a corresponding oriented version of said one direction pattern based on a location of the second traffic light apparatus.

Abstract: Dynamically configurable traffic controllers and methods of using the same are disclosed. An example apparatus includes a first display facing a first direction; a second display facing a second direction; a third display facing a third direction; and a processor, in response to a first input being received indicative of traffic approaching the first display and no traffic approaching the second display and the third display, the processor to cause the second display and the third display to display a first signal and for the first display not to display the first signal or a second signal, the first signal providing a first warning level, the second signal providing a second warning level greater than the first warning level, the first signal illuminatable on the second display, the second signal illuminatable on the second display, the first signal, when illuminated, disposed within a perimeter of the second signal, when illuminated.

Abstract: The invention relates to a traffic signal mode field, discloses a method for a greenwave mode of traffic signal control that can relieve jammed traffic in 2 cross directions in a roadnet, the control method comprises the following steps: 1) calculating and allocating of RATIO mode with obtaining the jammed vehicle queue start-time of road-segments; 2) calculating and allocating of the 2D-Jam-Relief greenwave time-offset; run RATIO after the 2D-Jam-Relief greenwave time-offset runs out. The present invention shows that 2D-Jam-Relief greenwave signals mode obtains higher efficient by 50% in relieving heavy traffic jam in a roadnet than 1D-Jam-Relief greenwave mode, by 100% than mode RATIO, greatly improve the efficiency of traffic signal control and traffic.

Abstract: A traffic adjustment or a traffic command, for example, is based on data congestion on a cellular network. Position data is received from a mobile device. A portion of a cellular network that corresponds to the position data is selected. The portion of the cellular network may be the geographic area covered by a cell. The network state of the portion of the cellular network is identified. A traffic device is also identified. The traffic device may be a traffic light or a variable speed sign. The traffic adjustment or traffic command for the traffic device is calculated based on the network state.

Abstract: A traffic control device (TCD) is described for managing control of multiple right of way passages at a traffic intersection. The TCD includes a mobile wireless interface for communicating with an in-vehicle mobile wireless device (IV-MWD) to receive a commuter profile (CP) containing a subscribed switch time interval (SSTI). The TCD determines a set of passage priority values for respective ones of a set of controlled right of way passages. The TCD selects, based upon the set of passage priority values, a highest priority one of the set of controlled right of way passages as a next controlled right of way passage granted passage. The TCD resets a timer duration value associated with a next controlled right of way passage period, executes a right of way passage switch. Thereafter, the TCD maintains a current switch status of the traffic control device for a period corresponding to the timer duration value.

Abstract: An automated traffic control process and system providing automatic remote monitoring the locations of one or more remote vehicles, determining which vehicles fall within one or more preference categories, and if a vehicle in a particular preference category is detected as approaching a remote intersection, issuing a preemption instruction to a traffic signal controller for the remote intersection. Various other process and system features can include one or more among: monitoring numerous vehicles and intersections, vehicle location monitoring, categorization, and issuance of preemption instructions on a centralized computing system; safety or other condition assessment and control of issuance of signaling instructions accordingly; determination of whether one or more the traffic intersection signaling controller should be operating according to one among differing hierarchical condition categories, and issuance of instructions causing remote traffic signaling to lock in a particular state, such as, for example in a right of way state.
