Transportation Information Center Connected Vehicle Roadside Equipment traveler information application info Moderate Moderate Low
This information could be of interest to a malicious individual who is attempting to determine the best way to accomplish a crime. As such it would be best to not make it easily accessible. If this is compromised, it could send unnecessary maintenance workers, or cause the appearance of excessive traffic violations, leading to further unnecessary investigation. A delay in reporting this may cause a delay in necessary maintenance, but (a) this is not time-critical and (b) there are other channels for reporting malfunctioning. Additionally, there is a message received notification, which means that RSE can ensure that all intersection safety issues are delivered.
Transportation Information Center Media traveler information for media Low Moderate Moderate
This information is intended for distribution to all members of the traveling public. Traffic information needs to be accurate, as it will be used by travelers to make decisions regarding their travel. Inaccurate or corrupted data could reduce overall mobility and certainly impact individual drivers. There should be other means for getting this information, but as this is the 'source flow' for a wide area broadcast with a huge potential distribution, the breadth of the impact covers all travelers.

Transportation Information Center Personal Information Device broadcast traveler information Not Applicable Moderate Low
By definition this is publicly broadcast data. The distribution of this data is intended to be very large, as such the impact of corrupted data will be significant. Probably not HIGH, as there are other distribution channels for this data. There are multiple channels for the delivery of this information, so if this one is not available, others will work.
Transportation Information Center TIC Operator TIC operations information presentation Moderate High High
Backoffice operations flows should have minimal protection from casual viewing, as otherwise imposters could gain illicit control or information that should not be generally available. Backoffice operations flows should generally be correct and available as these are the primary interface between operators and system.

Probably not HIGH, as there are other distribution channels for this data. There are multiple channels for the delivery of this information, so if this one is not available, others will work. DISC: WYO suggests this is LOW.
Traveler Personal Information Device traveler input Not Applicable Moderate Low
This data is informing the vehicle of operational information that is relevant to the operation of the vehicle. It should not contain anything sensitive, and does not matter if another person can observe it. While public, information must be correct or travelers may make incorrect decisions with regard to their travel plans. Information is available through other means, though depending on the location this might not always be the case, in which case this would be MODERATE.
Traveler Traveler Support Equipment traveler input Not Applicable Moderate Low
Publicly available information, while not directly observable, is intended for widespread distribution While public, information must be correct or travelers may make incorrect decisions with regard to their travel plans. Information is available through other means, though depending on the location this might not always be the case, in which case this would be MODERATE.
Traveler Support Equipment Traveler traveler interface updates Not Applicable Moderate Moderate
Publicly available information, while not directly observable, is intended for widespread distribution Should be accurate as the Traveler will be relying on this information for routing and related choices. Lack of accuracy will result in lack of confidence from the traveler as well as an unsatisfactory trip, leading to a negative feedback spiral. Users expect their devices to work. If information is not presented to the operator, the relevant applications simply won't be used.
Vehicle Driver driver updates Not Applicable Moderate Moderate
This data is informing the driver about the safety of a nearby area. It should not contain anything sensitive, and does not matter if another person can observe it. This is the information that is presented to the driver. If they receive incorrect information, they may act in an unsafe manner. However, there are other indicators that would alert them to any hazards, such as an oncoming vehicle or crossing safety lights. If this information is not made available to the driver, then the system has not operated correctly.
Weather Service System Transportation Information Center qualified environmental conditions data Low Moderate Low
If this data were exposed there would be little to no harm, except that the exposure was not authorized and the sender had no knowledge of downstream data usage. That alone is difficult to judge as 'serious harm' so left at LOW. Since the point of this particular flow is to provide data that is already quality checked, corruption of this data would have a significant negative impact on the users of this data. This flow is used to help guide traveler actions. There should be other compensating flows and sources of this type of information if this one is not available, which justifies LOW.
Weather Service System Transportation Information Center weather information Low Moderate Moderate
WYO believes this should be LOW or MODERATE depending on the application. While there are many sources of weather information, some guarantee of correctness is justifiable to keep confidence in provided service. There should be other sources of this data. It does need to be reliable however; weather can change quickly, and depending on the destination and its operational strategies, timely response may be important.
