DISCLAIMER

FAST does not continually save records of all database changes. We cannot guarantee that the plan you will receive is the actual database in effect at the time in question. There are numerous events not tracked which can significantly alter the operation and sequencing of a traffic signal. These include emergency vehicle preemptions, detector failures, and lack of detector calls for specific traffic movements. In addition to these events, technicians from local agencies that are responsible for maintaining the traffic signals sometimes make timing changes in response to site-specific timing concerns. We do not track these changes. If local agency technicians changed timing at the intersection it will not be reflected in the attached database.
