Abstract: A blocker vehicle for blocking a scene on a road includes a frame, a body assembly supported on the frame, and a collision avoidance and mitigation system (CAMS) including a CAMS module. The CAMS module includes a housing and at least one of a sensor or a camera that is supported by the housing and has a field of view. The CAMS module is rotatably coupled to the body assembly so that the field of view is selectively rotatable between an initial position where the field of view is misaligned with the road and an aligned position where the field of view is aligned with the road.

Abstract: A vehicle system includes a blocker vehicle, a vision system, and one or more processing circuits. The blocker vehicle includes an alert system. The vision system includes at least one of a camera, a lidar sensor, or a radar sensor. The vision system is configured to acquire vision data regarding an approaching vehicle approaching the blocker vehicle. The one or more processing circuits are configured to evaluate a threat level of the approaching vehicle based on the vision data and transmit an alert signal to at least one of the alert system, the approaching vehicle, or a portable device worn or carried by a person associated with the blocker vehicle in response to the threat level exceeding a threat threshold.

Abstract: A vehicle is configured to be positioned upstream of traffic relative to a scene to protect personnel responding to the scene. The vehicle includes a collision avoidance and mitigation system configured to alert personnel on the scene of a threat caused by an approaching vehicle and/or alert the driver of the approaching vehicle of the scene. The collision avoidance and mitigation system is configured to determine a threat score based on a past trajectory of a detected vehicle and a number of previously observed trajectories of vehicles approaching the scene. The collision avoidance system can generate a threat score for the detected vehicle and adjust the threat score based on a comparison of the past trajectory to the number of previously observed trajectories. An alert signal is generated responsive to the threat score exceeding a threshold.

Abstract: A collision avoidance and mitigation system (CAMS) includes a CAMS module having a housing and at least one of a sensor or a camera that is supported by the housing and one or more processing circuits. The one or more processing circuits being configured to acquire second CAMS data via a roadway camera positioned along a roadway regarding an approaching vehicle, evaluate a threat level of the approaching vehicle based on the second CAMS data, and transmit an alert signal to at least one of an alert system associated with the CAMS module, the approaching vehicle, or a portable device associated with the CAMS module in response to the threat level exceeding a threat threshold.

Abstract: A scene monitoring system includes a personnel device configured to be carried by personnel on a scene, a sensor unit, and one or more processing circuits configured to monitor one or more characteristics associated with an approaching vehicle based on data acquired by the sensor unit, monitor a location of the personnel device about the scene, establish a restricted area including the scene and the personnel device, determine (i) a threat level associated with the approaching vehicle and (ii) a vulnerable area of the restricted area based on the one or more characteristics associated with the approaching vehicle, and provide an alert to the personnel device located within the vulnerable area in response to the threat level to the vulnerable area exceeding a threat threshold.

Abstract: A vehicle is configured to be positioned upstream of traffic relative to a scene to protect personnel responding to the scene. The vehicle includes a collision avoidance and mitigation system configured to alert personnel on the scene of a threat caused by an approaching vehicle and/or alert the driver of the approaching vehicle of the scene. The collision avoidance and mitigation system is configured to determine a restricted zone around the vehicle. The restricted zone is determined by detecting scene markers or personnel at the scene or the restricted zone can be entered via a user interface. The restricted zone can be updated as the scene markers are deployed or personnel move around the scene. An alert is generated responsive to a threat score related to the probability of the approaching vehicle entering the restricted zone exceeding a threshold.

Abstract: A vehicle includes a display positioned within the vehicle, at least one sensor positioned to facilitate (i) monitoring an area in front of the vehicle as the vehicle is responding to a scene and (ii) detecting an object in the area in front of the vehicle that is imperceptible to an operator because of a visibility-impairing condition, and a control system configured to generate a graphical representation of the area and the object for display to the operator on the display based on sensor data acquired by the at least one sensor to facilitate operation of the vehicle by the operator through the visibility-impairing condition.

Abstract: A collision avoidance and mitigation system (CAMS) includes a deployable CAMS module supported on a base or a stand and including at least one of a first sensor or a first camera that has a first field of view and a CAMS module including a housing and at least one of a second sensor or a second camera that is supported by the housing and has a second field of view. The CAMS includes one or more processing circuits configured to: acquire the first CAMS data regarding an approaching vehicle, evaluate a threat level of the approaching vehicle based on the first CAMS data, and transmit an alert signal to at least one of an alert system associated with the CAMS module, the approaching vehicle, or a portable device associated with the CAMS module in response to the threat level exceeding a threat threshold.

Abstract: A scene system includes a vehicle configured to be positioned proximate a scene between an approaching vehicle and the scene, a sensor unit, and one or more processing circuits configured to monitor one or more characteristics associated with the approaching vehicle based on data acquired by the sensor unit, determine a threat level associated with the approaching vehicle based on the one or more characteristics associated with the approaching vehicle, and transmit a control signal to the approaching vehicle based on the threat level, wherein the control signal is configured to at least one of (i) cause the approaching vehicle to provide an indication regarding the vehicle and the scene to an operator of the approaching vehicle or (ii) limit or adjust operation of the approaching vehicle.

Abstract: A collision avoidance and mitigation system (CAMS) includes a deployable drone including at least one of a first sensor or a first camera that has a first field of view and a CAMS module. The CAMS module includes a housing and at least one of a second sensor or a second camera that is supported by the housing and has a second field of view. The CAMS includes one or more processing circuits configured to acquire the first CAMS data regarding an approaching vehicle, evaluate a threat level of the approaching vehicle based on the first CAMS data, and transmit an alert signal to at least one of an alert system associated with the CAMS module, the approaching vehicle, or a portable device associated with the CAMS module in response to the threat level exceeding a threat threshold.
