Typically MODERATE for applications with a high degree of commercial vehicle parking, but could be LOW otherwise.
Payment Administration Center Transportation Information Center toll data Low Moderate Low
Should be public information, little benefit to obscuring this information. Since actors may use this information to plan their travels, it must be correct. Corruption or manipulation of this data may lead them to make suboptimal decisions, costing time and/or money. This flow probably does not update often. The information within is distributed via many routes.
Personal Information Device Social Media traveler request Moderate Moderate Low
This is likely to include the traveler location and may include traveler identity as well. This PII could be used by an attacker to the detriment of the traveler. Request needs to be correct, or the wrong data may be sent. If this interface is not available the traveler will likely find other means to acquire the necessary information.

Personal Information Device Traveler traveler interface updates Not Applicable Moderate Moderate
Personalized data that includes directions and guidance for an individual, but eventually evident anyway. 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.
Social Media Personal Information Device interactive traveler information Moderate Moderate Low
Personalized traveler information implies location, intent and/or future location, which if compromised could enable an attacker with leverage over the traveler. Traveler information needs to be correct, as the traveler is using this to make transport-related decisions. Travelers will rely on this data for transportation-related decisions. Depending on the number of options, possible choices and impacts, this may be MODERATE.
Social Media Transportation Information Center traveler sourced updates Moderate Moderate Low
This is likely to include the traveler location and may include traveler identity as well. This PII could be used by an attacker to the detriment of the traveler. Quality of social media inputs may be highly variable, but no publicly distributable data should be exchanged without some protection over its transmission.
