TM09: Integrated Decision Support and Demand Management

This service package recommends courses of action to transportation operators in a corridor, downtown area, or other heavily traveled area. Recommendations are based on an assessment of current and forecast transportation network performance and environmental conditions. Multi-modal transportation operational strategies are created that consider all modes and all roads in the travel area to correct network imbalances and effectively manage available capacity. As part of the operational strategies, this service package may also recommend lane restrictions, transit, parking, and toll strategies to influence traveler route and mode choices to support active demand management programs and policies managing both traffic and the environment. Operational strategies, including demand management recommendations, are coordinated to support operational decisions by each transportation operator that are consistent with the recommended strategy. All recommended operational strategies are based on historical evaluation, real-time assessment, and forecast of the roadway network performance based on predicted travel demand patterns. This service package also collects air quality, parking availability, transit usage, and vehicle occupancy data to support operational strategies that manage and balance capacity and demand.

Emergency Management Center Traffic Management Center incident information High Moderate Moderate
This data contains all of the information regarding the incident. This could include personal information regarding persons involved in the incident. It could also include sensitive information regarding special events or closures. Minor discrepancies in this data should not have a catastrophic effect, but it should be reasonably controlled and accurate. A few missed messages should not have a significant effect. However, most messages should make it through and the EMC should be able to know if the TMC has received a message.
Emissions Management Center Traffic Management Center air quality information Not Applicable Moderate Low
This flow does not contain any personal or confidential information, and the data contained is eventually intended for public consumption. Information for general distribution should have at least some guarantee that it was correctly transmitted. If this information were incorrect, people could be exposed to higher levels of pollution than they would intend, which could be harmful to people with medical conditions such as asthma. Not a key flow for any service package. If an application is developed that relies on this flow, may change to MODERATE.
Event Promoter System Traffic Management Center event plans Moderate High Moderate
This will include PII of the event contact person, which should be protected from casual viewing. This flow will also include details of the planned event, which in some circumstances might not be entire public information and so again, should not be casually viewable. Personal contact information needs to be correct, but so do the details of the planned event because of the potential severity of the event's impact. Generally the more significant the potential impact of the event, the higher this should be, but never below MODERATE. There should be other mechanisms for getting this information, otherwise it would match integrity.

Other Traffic Management Centers Traffic Management Center incident information High Moderate Moderate
This data contains all of the information regarding the incident. This could include personal information regarding persons involved in the incident. It could also include sensitive information regarding special events or closures. Incident response and planning details need to be accurate or incorrect decisions or expectations may result, having a significant impact on mobility and operations. Real-time access to incident response information is important to management of transportation assets and incident response assets, but does not warrant 'High' because this flow is about adjacent centers, and has no direct impact on the response being given.
Other Traffic Management Centers Traffic Management Center road network conditions Low Moderate Moderate
No harm should come from seeing this data, as it is eventually intended for public consumption. While accuracy of this data is important for decision making purposes, applications should be able to corroborate the data in many instances. Thus MODERATE generally. Depends on the application; if mobility decisions that affect large numbers of travelers are made based on this data, then it is MODERATE. In more modest circumstances, it may be LOW.

No PII is involved. However this flow should contain coordinated response information: how various transportation related entities respond to different conditions. This type of information is block intelligence that could be useful to an attacker or criminal, and thus should not be distributed in the clear. If this information is corrupted or modified, transportation management entities may not have well integrated plans for one or more operational scenarios, impacting mobility and safety in those conditions. Given that this data exchange is likely the product of personal work between agencies, and that follow up is likely, justify MODERATE and not HIGH. Probably not updated often, but could contain large amounts of information; additionally in times of crisis may need some more update, so MODERATE justifiable.
