  • Patent number: 10203214
    Abstract: An approach is provided for filtering device location points in a sampled trajectory while maintaining path reconstructability. The approach involves determining a first location point in the sampled trajectory that is an unfiltered location point. The sampled trajectory includes device location points sampled by a device traversing a road network. The approach also involves determining a fastest alternative path from the first location point to a second location point. The approach further involves calculating a sampling time difference between a time at which the first location point was sampled and another time at which the second location point was sampled. The approach further involves designating the second location point as a next unfiltered location point when the sampling time difference is within a threshold value of a free-flow travel time calculated for the fastest alternative path. Otherwise, the second location point is designated as a filtered location point.

  • Patent number: 10008113
    Abstract: Computer-implemented predictions of upcoming traffic control signal states or state changes can be used to improve driver convenience, safety, and fuel economy. Such information can be used advantageously by a human operator, or by an autonomous or semi-autonomous vehicle control system. Predictions can be computed with suitable machines installed in a vehicle, in cooperation with a remote back-end server system. The prediction computations in the vehicle may be supported by data communicated to the vehicle computing machinery over various wireless communications, including telecom systems, DSRC, etc.

  • Patent number: 9972199
    Abstract: Technologies are described to provide control of traffic signals based at least in part on the presence of non-motorized users. In some examples, a system may include at least one sensor configured to autonomously acquire motorized user presence data at an intersection, and at least one sensor configured to autonomously acquire non-motorized user presence data at the intersection. The system may also include an agent configured to determine a motorized user queue length based on the motorized user presence data, determine a non-motorized user queue length based on the non-motorized user presence data, and control the traffic signals based at least in part on the non-motorized user queue length.

  • Patent number: 9947219
    Abstract: A traffic control system can includes a plurality of traffic lights. A monitoring system can include an inbound interface component, an analytics component, and an outbound status provisioning component. The inbound interface component can be configured to receive a stream of sensor data from visual sensor(s). Each visual sensor can be configured to capture light signals of traffic lights. Each traffic light can be sensed by the visual sensor(s). The received stream of sensor data can represent a current signal status of each traffic light. The analytics component can be configured to predict at least one future signal status for each of the traffic lights based on the use of a machine learning algorithm. The outbound status provisioning component can be configured to send a message(s) to a vehicle. The sent message can influence the operation of the vehicle.

  • Patent number: 9930148
    Abstract: A roadside signal system and a roadside controller are provided relating to the control and operation of roadside signals and signs, such as those used by departments of transportation and municipalities. The roadside signal system and controller are configured to operate using National Transportation Communications for Intelligent Transportation Systems Protocol (“NTCIP”) compliant transmissions at both a local and remote level. The roadside controller by itself and as a part of the roadside signal system operates a local network to control multiple signs or signals from a single connection to a central network, thus saving physical space within the roadside cabinets used to store such controllers and virtual network space on the central network.

  • Patent number: 9922556
    Abstract: The present invention is a system and method for dynamically and accurately allocating green light time of a traffic light at a given intersection by counting the number of vehicles located in an approach to a given intersection. A signal controller radio transceiver of a stationary intersection mounted control unit (CU) receives identifying signals transmitted by the on board vehicle radio transceiver of vehicles located at an approach to this intersection. A signal controller interface processing unit of the CU at the given intersection is operable to disregard signals transmitted by vehicles located at one or more upstream intersections and by pedestrians and passengers of a common motor vehicle. The number of vehicles located at an approach is thereby counted, allowing the CU to dynamically allocate green light time of a corresponding traffic light in accordance with traffic arrangement, for example per approach or per signal group, and design preferences.
