Characteristics of a vehicle, e.g., operating conditions, characteristics of the one or more vehicle occupants, e.g., age, demographic, driving record, purchase history, etc. and/or road conditions, e.g., weather-related road conditions, current traffic conditions, etc., may be obtained. Information relevant to the one or more vehicle occupants based on one or more of these characteristics/conditions may presented to the one or more vehicle occupants. In scenarios where the presentation of personalized information is unwanted/unwarranted, more generalized information and/or safety warnings or recommendations can be presented. ## Claims ### Claim 1 A method for presenting to a vehicle, personalized and generalized information on a road sign, the method comprising: a processor receiving sensor data from a sensor and using the sensor data to determine proximity of the vehicle to the road sign; receiving data regarding at least one of operating characteristics of the vehicle and characteristics of one or more occupants of the vehicle; determining road conditions proximate to the road sign, wherein the road conditions proximate to the road sign comprise a quantity of vehicles forming roadway congestion; determining whether or not to present information on the road sign based on the quantity of vehicles forming the roadway congestion; upon a determination that the quantity of vehicles exceeds the vehicle threshold, presenting generalized information on the road sign; and upon a determination that the quantity of vehicles does not exceed the vehicle threshold, presenting the personalized information on the road sign. ### Claim 2 (depends on 1) The method of claim 1, wherein receiving data regarding the at least one of operating characteristics of the vehicle comprises communicating with the at least one of an electronic control unit and one or more sensors of the vehicle over a vehicle-to-infrastructure communications channel to a roadside unit associated with the road sign. ### Claim 3 (depends on 1) The method of claim 1, wherein the operating characteristics of the vehicle comprise at least one of vehicle speed, vehicle acceleration, travel origin, travel destination, lane change history, and continuous operation time. ### Claim 4 (depends on 1) The method of claim 1, wherein receiving data regarding characteristics of one or more occupants of the vehicle comprises: receiving at least one of biometric sensor signals from biometric sensors associated with the vehicle; receiving vehicle associated account information regarding the one or more occupants of the vehicle; and receiving information suggestive of at least one of the one or more occupants' travel preferences, travel history, purchase preferences, purchase history, and demographic information associated with the one or more occupants of the vehicle. ### Claim 5 (depends on 1) The method of claim 1, wherein the generalized information is based upon at least one of operating characteristics of a group of vehicles proximate to the road sign, common characteristics of one or more occupants of each vehicle in the group of vehicles, and road conditions data applicable to the group of vehicles. ### Claim 6 (depends on 1) The method of claim 1, wherein the presentation of the generalized information or the personalized information is delayed in accordance with the roadway congestion. ### Claim 7 (depends on 1) The method of claim 1, wherein the presentation of the personalized information is provided by a speaker incorporated with the road sign. ### Claim 8 (depends on 1) The method of claim 1, wherein the presentation of the personalized information is provided by a speaker incorporated with the vehicle. ### Claim 9 (depends on 1) The method of claim 1, wherein the road sign is a first road sign, and the data regarding the operating characteristics of the vehicle is a speed of the vehicle, the method further comprising: upon determining that the speed of the vehicle exceeds a threshold speed, determining a second road sign for presenting the information, wherein the second sign is a greater distance from the vehicle than the first road sign. ### Claim 10 (depends on 1) The method of claim 1, the method further comprising: prior to presenting the personalized information on the road sign, determining to present the personalized information on another road sign, based upon a change in at least one of visibility of the road sign, speed of travel of the vehicle, direction of travel of the vehicle, and lane change. ### Claim 11 A system for presenting to a vehicle, personalized and generalized information on a road sign, the system comprising: a memory; and a processor that is configured to execute machine readable instructions stored in the memory for performing a method comprising: receiving sensor data from a sensor and using the sensor data to determine proximity of the vehicle to the road sign; receiving data regarding at least one of operating characteristics of the vehicle and characteristics of one or more occupants of the vehicle; determining road conditions proximate to the road sign, wherein the road conditions proximate to the road sign comprise a quantity of vehicles forming roadway congestion; determining whether or not to present information on the road sign based on the quantity of vehicles forming the roadway congestion; upon a determination that the quantity of vehicles exceeds the vehicle threshold, presenting generalized information on the road sign; and upon a determination that the quantity of vehicles does not exceed the vehicle threshold, presenting the personalized information on the road sign. ### Claim 12 (depends on 11) The system of claim 11, wherein receiving data regarding the at least one of operating characteristics of the vehicle comprises communicating with the at least one of an electronic control unit and one or more sensors of the vehicle over a vehicle-to-infrastructure communications channel to a roadside unit associated with the road sign. ### Claim 13 (depends on 11) The system of claim 11, wherein the operating characteristics of the vehicle comprise at least one of vehicle speed, vehicle acceleration, travel origin, travel destination, lane change history, and continuous operation time. ### Claim 14 (depends on 11) The system of claim 11, wherein the machine readable instructions stored in the memory further perform the method comprising: receiving at least one of biometric sensor signals from biometric sensors associated with the vehicle; receiving vehicle associated account information regarding the one or more occupants of the vehicle; and receiving information suggestive of at least one of the one or more occupants' travel preferences, travel history, purchase preferences, purchase history, and demographic information associated with the one or more occupants of the vehicle. ### Claim 15 (depends on 11) The system of claim 11, wherein the generalized information is based upon at least one of operating characteristics of a group of vehicles proximate to the road sign, common characteristics of one or more occupants of each vehicle in the group of vehicles, and road conditions data applicable to the group of vehicles. ### Claim 16 (depends on 11) The system of claim 11, wherein the presentation of the generalized information or the personalized information is delayed in accordance with the roadway congestion. ### Claim 17 (depends on 11) The system of claim 11, wherein the presentation of the personalized information is provided by a speaker incorporated with the road sign. ### Claim 18 (depends on 11) The system of claim 11, wherein the presentation of the personalized information is provided by a speaker incorporated with the vehicle. ### Claim 19 (depends on 11) The system of claim 11, wherein the road sign is a first road sign, and the data regarding the operating characteristics of the vehicle is a speed of the vehicle, and the machine readable instructions stored in the memory further perform the method comprising: upon determining that the speed of the vehicle exceeds a threshold speed, determining a second road sign for presenting the information, wherein the second sign is a greater distance from the vehicle than the first road sign. ### Claim 20 (depends on 11) The system of claim 11, wherein the machine readable instructions stored in the memory further perform the method comprising: prior to presenting the personalized information on the road sign, determining to present the personalized information on another road sign, based upon a change in at least one of visibility of the road sign, speed of travel of the vehicle, direction of travel of the vehicle, and lane change.
