Abstract: A method of investigation traffic flow includes receiving sensor data from at least one sensor describing a surface area within a field of view of at least one sensor. A current heat map is generated based on the sensor data. The current heat map is compared with a preexisting heat map of the surface area within the field of view. A MAP message is updated based on the comparison of the current heat map with the preexisting heat map.

Abstract: A disclosed vehicle guidance system includes a transceiver receiving information indicative of operating conditions of other vehicles along a roadway and a controller within a primary vehicle. The controller utilizes the received information indicative of operating conditions to determine a recommended vehicle path along the roadway responsive to the operation of the other vehicles, the position of the primary vehicle and a scenario selected based on both the information of operation of other vehicles and the position of the primary vehicle received by the controller. A communication device communicates the recommended vehicle path to the operator of the primary vehicle.

Abstract: A method for determining occupancy of a parking space using a heat map includes receiving sensor data from one or more sensors positioned such that a surface area is within a field of view, the sensor data at least indicating a speed and location of a traffic participant. Generating the heat map based on the traffic participant(s) and determining a heat index associated with each portion of the heat map. Determining a traffic participant is stopping, parking, or leaving a parking space based upon the change of speed movement between, high and low, and moving or parking, heat index portions.

Abstract: For each pair of traffic participants (TPs) entering an intersection, a time to collision (TTC) value is calculated. A matrix of TTC values between TPs entering the intersection is created. A matrix of criticality values containing a respective criticality value for each pair of TPs is created. Each criticality value is determined as a function of both TTC and at least one additional weighting factor. A basic safety message (BSM) and/or a pedestrian safety message (PSM) is broadcast on behalf of at least one traffic participant based on having determined the criticality for each pair of traffic participants and having identified a near-miss and/or a potential-collision situation between traffic participants based on the respective criticality values in the matrix of criticality values. One or more warnings are provided to a pedestrian, a driver of a vehicle, and/or a cyclist based on the broadcasted BSM and/or PSM.

Abstract: A method of controlling traffic at a first intersection having a first traffic light is disclosed, including monitoring traffic at the first intersection and storing traffic information from the monitoring in memory; receiving traffic information relating to one or more other intersections in an area in which the first intersection is located; determining a timing sequence for the first traffic light based at least in part upon the traffic information from the monitoring and the received traffic information; and updating control of the first traffic light to utilize the determined timing sequence.

Abstract: There is disclosed a system, method and software program for managing parking spaces in a geographical area. The system, method and software program includes monitoring the geographical area; identifying one or more available parking spaces in the geographical area based at least partly upon the monitoring; informing, over the air interface, one or more vehicle operators about a first available parking space of the one or more available parking spaces identified; and completing a parking reservation for the first available parking space with a first vehicle operator of the one or more vehicle operators.

Abstract: New measurement inputs for Kalman Filter or similar estimation approaches (at each sample) may include: DSRC messages from roadside transmitters (RSTs), such as: how long it takes for a DSRC signal from one or more fixed RSTs to reach the vehicle and comparison of that information with vehicle position estimates from a signal propagation model, which is based on how long it takes a DSRC signal to reach the vehicle GPS location from a fixed known RST location. From such measurements, it can be determined how much longer (or shorter) it takes to receive the RST message compared to the previous sample, which, in turn, gives an idea how far the vehicle has moved over a sample relative to a fixed RST location.

Abstract: A notification or warning system which alerts various drivers and pedestrians of a vehicle which is being driven erratically. A vehicle is capable of running a self-diagnosis on various vehicle dynamics data to determine if erratic driving is present, and the vehicle is also able to communicate (via Dedicated Short Range Communication (DSRC), WiFi, table devices, etc.) to alert other traffic participants (i.e., drivers of other vehicles or pedestrians) of such a situation. A plurality of detection devices detect when the vehicle is performing at least one undesirable driving maneuver, and transfer information regarding the undesirable driving maneuver to a first communication device. The first communication device transmits a signal to a second communication device such that the second communication device commands a notification device to generate a warning indicating that the vehicle is performing the undesirable autonomous driving maneuver.

Responsive to identifying the first object, the method performs one or more actions so the vehicle avoids the first object.
