    Abstract: Traffic flow control. A method identifies traffic in an area. The traffic includes traffic objects. The identifying obtains identifiers of traffic objects in the area. Each traffic object is identified by a respective identifier of the traffic object identifiers. The method also dynamically assigns weights to the traffic objects based on pre-established traffic criteria. Each traffic object is assigned a respective weight of the dynamically assigned weights. The pre-established traffic criteria each include at least one weight value. The weight assigned to a traffic object is based on the weight values of a set of traffic criteria, of the pre-established traffic criteria, applicable to the traffic object and reflects a level of prioritization of a right-of-way of the traffic object. The method also controls flow of the traffic in the area. The controlling the flow includes controlling at least one traffic control signal based on the dynamically assigned weights.

    Abstract: An system, method, and non-transitory computer readable medium for managing traffic at a worksite. The system includes a traffic control signal, a wireless interface, a mast, a support base, a wireless control device, and a base station for communicating between the wireless interface and the wireless control device. The method involves receiving input from the wireless control device, generating a control signal got the traffic control signals. The non-transitory computer readable medium is encoded with codes for directing a processor to carry out the method.

    Abstract: Traffic at an intersection, or other portion of a road, is detected, and the stop/go traffic signal apparatus at the intersection, or other portion is controlled based on vehicle types in the detected traffic. A vehicle type may be determined based on information collected by that vehicle's onboard telematics unit, or with a user's device in communication therewith. An input may be received from a user device, onboard the vehicle, to request changing the current stop/go configuration of the traffic signal. The request may be processed based on the determined vehicle type to determine whether or nor to change the traffic signal in response to the request. The request may be accompanied by an offer of money, and if the request is not granted, the user device may forward another request associated with a different offer.

    Abstract: For each of the traveling directions (traveling direction 1 to traveling direction 4) at an intersection, a traffic-light cycle length estimation device acquires a time at which a vehicle in the stopped state starts moving, calculates the time difference between neighboring start times, which have been acquired, as a start interval, and generates a histogram based on the number of samplings of start intervals. The device combines the generated histograms into a histogram for all direction to generate one histogram that represents the relation between the start intervals and the number of samplings and, based on this histogram, estimates the cycle length of the traffic light. If a particular value, one of the start intervals, corresponds to the maximum number of samplings, that particular value is estimated as the cycle length.

    Abstract: The present invention extends to methods, systems, and computer program products for detecting targets across beams at roadway intersections. Embodiments of the invention include tracking a target across a plurality of beams of a multiple beam radar system in a roadway intersection and updating track files for targets within a roadway intersection. Returns from a plurality of radar beams monitoring a roadway intersection are divided into range bins. Identified energy in the range bins is used to compute the position of targets within a roadway intersection. When the position of a target is computed, it is determined if the position is a new position for an existing target or if the position is the position of a new target.

    Abstract: Today's infrastructures allow for a single signal per lane that works in a stop and go fashion. Every vehicle that requires access the shared resource traffic junction moves through the junction when it is given a green signal. If not, they wait in a line which is service First Come First Served (FCFS) manner. Intuitively, the probability of waiting is higher compared to moving in today's deployments. We propose an intelligent control system that adaptively streamlines the traffic using multiple traffic signals per lane. The traffic signals have the capability of alerting the vehicles on the speed to travel for smooth crossing of all signals to access the shared resource traffic junction. With vehicles moving continuously, the waiting time is minimized. In addition, the method reduces pollution and gas expense while maximizing the utilization of the shared resource traffic junction capacity.

    Abstract translation: 今天的基础设施允许每个车道单个信号停止和走向时尚。 当给予绿色信号时，需要访问共享资源流量连接点的每个车辆将通过该路口。 如果没有，他们会等待一线即服务First Come First Served（FCFS）的方式。 直觉上，与今天部署中的移动相比，等待的概率更高。 我们提出一种智能控制系统，可以通过每个车道使用多个交通信号来自适应地简化交通流量。 交通信号能够以高速行驶的车辆进行警报，以便所有信号的顺利交叉以接入共享资源交通枢纽。 随着车辆连续移动，等待时间最小化。 此外，该方法减少了污染和燃气费用，同时最大限度地利用了共享资源交通枢纽的能力。
