Rail Operations Center --> Transportation Information Center:
railroad schedules

Definitions

railroad schedules (Information Flow): Train schedules, maintenance schedules, and other information from the railroad that supports forecast of HRI closures.

Rail Operations Center (Source Physical Object): 'Rail Operations Center' represents the (usually) centralized control point for a substantial segment of a freight railroad's operations and maintenance activities. It is roughly the railroad equivalent to a highway Traffic Management Center. It is the source and destination of information that can be used to coordinate rail and highway traffic management and maintenance operations. It is also the source and destination for incident, incident response, disaster, or evacuation information that is exchanged with an Emergency Management Center. The use of a single object for multiple sources and destination for information exchange with railroads implies the need for a single, consistent interface between a given railroad's operations and maintenance activities and ITS.

Transportation Information Center (Destination Physical Object): The 'Transportation Information Center' collects, processes, stores, and disseminates transportation information to system operators and the traveling public. The physical object can play several different roles in an integrated ITS. In one role, the TIC provides a data collection, fusing, and repackaging function, collecting information from transportation system operators and redistributing this information to other system operators in the region and other TICs. In this information redistribution role, the TIC provides a bridge between the various transportation systems that produce the information and the other TICs and their subscribers that use the information. The second role of a TIC is focused on delivery of traveler information to subscribers and the public at large. Information provided includes basic advisories, traffic and road conditions, transit schedule information, yellow pages information, ride matching information, and parking information. The TIC is commonly implemented as a website or a web-based application service, but it represents any traveler information distribution service.

Communication Solutions

Solutions are sorted in ascending Gap Severity order. The Gap Severity is the parenthetical number at the end of the solution.

Selected Solution

(None-Data) - Apache Kafka

Solution Description

This solution is used within the U.S.. It combines standards associated with (None-Data) with those for Apache Kafka. The (None-Data) standards include an unspecified set of standards at the upper layers. The Apache Kafka standards include lower-layer open source code that supports data distribution of specific types of data.

  Confidentiality Integrity Availability
Rating Low Moderate Moderate
Basis Does not contain any personal or confidential information. While accuracy of this data is important for decision making purposes, the greatest impact if manipulated or incorrect data would be financial and likely limited in scope. For example, making all options appear less expensive than an attacker's route of fiduciary interest, driving revenue to his route. This is undesireable and significant, but not catastrophic. Thus MODERATE generally. While accuracy of this data is important for decision making purposes, applications should be able to function without frequent updates. Thus MODERATE generally, though it could be LOW depending on the level of projected updates.
