These ruleset modules may not be implemented for the prototype - the rulesets may be implemented in the wayside. A pairwise comparison was used to develop our comparative weighting. References in literature will be provided upon request. There may be more than one bus on-board, but a second bus could provide a gateway to the PTC bus, or other applications could be put on the PTC bus. We anticipate that the PTC bus will have the capacity to support additional applications, however we are still collecting data estimates of other applications.
Capacity is one issue, but impact to safety is our primary concern.
It is typical for a control system to operate on deterministic message sets - data sets gathered with same time steps for processing. We believe that the time precision needed for this application does not require this level of precision. We intend to have single LSI gateway. Train length is used in messages. The head and tail location information is in the location object.
