Systems for coordinating actions of a first vehicle and a second vehicle upon detection of a potential safety hazard in or near a roadway, including in part evaluating whether the actions conflict and, if so, requesting that the first vehicle execute alternative actions for avoiding or mitigating risk of collision. Corresponding methods are disclosed. ## Claims ### Claim 1 A system for automatically warning at least one nearby vehicle of a potential safety hazard in or near a roadway, the system comprising: one or more sensors configured to detect a potential safety hazard in or near a roadway; a memory containing computer-readable instructions for generating a message including at least one of a location of the one or more sensors and a location of the potential safety hazard; a processor configured to read the computer-readable instructions from the memory and generate the message; and a transmitter configured to wirelessly transmit the message to at least one nearby vehicle. ### Claim 2 (depends on 1) The system of claim 1, wherein the one or more sensors include at least one of a camera, an image sensor, an optical sensor, a sonic sensor, a traction sensor, a wheel impact sensor, and a location sensor. ### Claim 3 (depends on 1) The system of claim 1, wherein the location of the potential safety hazard is determined by or using information provided by the one or more sensors. ### Claim 4 (depends on 3) The system of claim 3, wherein the one or more sensors includes at least one sensor configured to measure a distance between the sensor and the potential safety hazard. ### Claim 5 (depends on 1) The system of claim 1, wherein the one or more sensors include at least one sensor configured for measuring at least one of a velocity and heading of the potential safety hazard, wherein the message includes the location of the potential safety hazard, and wherein the message further includes at least one of the measured velocity and heading of the potential safety hazard. ### Claim 6 (depends on 1) The system of claim 1, wherein the one or more sensors are located onboard a first vehicle. ### Claim 7 (depends on 6) The system of claim 6, wherein the one or more sensors include at least one sensor configured for measuring at least one of a velocity and heading of the first vehicle, wherein the message includes the location of the first vehicle, and wherein the message further includes at least one of the measured velocity and heading of the first vehicle. ### Claim 8 (depends on 5) The system of claim 5, wherein the message further includes a time stamp indicating when the message was generated. ### Claim 9 (depends on 1) The system of claim 1, wherein the processor is further configured to identify a nature of the potential safety hazard using, at least in part, information collected by the one or more sensors, and wherein the message further includes information concerning the nature of the potential safety hazard. ### Claim 10 (depends on 1) The system of claim 1, wherein the one or more sensors are deployed in or near the roadway. ### Claim 11 A method for automatically warning at least one nearby vehicle of a potential safety hazard in or near a roadway, the method comprising: detecting a potential safety hazard in or near a roadway using one or more sensors; generating a message including information concerning at least one of a location of the one or more sensors and a location of the potential safety hazard; and transmitting the message wirelessly to at least one nearby vehicle. ### Claim 12 (depends on 11) The method of claim 11, wherein the one or more sensors include at least one of a camera, an image sensor, an optical sensor, a sonic sensor, a traction sensor, a wheel impact sensor, and a location sensor. ### Claim 13 (depends on 11) The method of claim 11, further including determining the location of the potential safety hazard using information provided by the one or more sensors. ### Claim 14 (depends on 11) The method of claim 11, wherein determining the location of the potential safety hazard includes: measuring a distance between at least one of the one or more sensors and the potential safety hazard, and relating the distance to a location of the one or more sensors. ### Claim 15 (depends on 11) The method of claim 11, further including: measuring at least one of a velocity and heading of the potential safety hazard, including, in the message, the location of the potential safety hazard and at least one of the measured velocity and heading of the potential safety hazard. ### Claim 16 (depends on 11) The method of claim 11, wherein the one or more sensors are located onboard a first vehicle, and further including: measuring at least one of a velocity and heading of the first vehicle, and including, in the message, the location of the first vehicle and at least one of the measured velocity and heading of the first vehicle. ### Claim 17 (depends on 15) The method of claim 15, further including in the message a time stamp indicating when the message was generated. ### Claim 18 (depends on 11) The method of claim 11, further including: identifying a nature of the potential safety hazard using, at least in part, information collected by the one or more sensors, and including, in the message, information concerning the nature of the potential safety hazard. ### Claim 19 (depends on 11) The method of claim 11, wherein the method is implemented according to instructions stored on a non-transitory machine readable medium that, when executed on a computing device, cause the computing device to perform the method.
