Description: | A. PURPOSE | This dataset serves as an inventory of traffic signal and related equipment.| B. METHODOLOGY | N/A| C. UPDATE FREQUENCY | Signals Access database updated regularly (weekly, or quarterly) based on SRC work orders returned to date. GIS file updated quarterly. | D. OTHER CRITICAL INFO | Attribute data primarily maintained in the Access database. Spatial data exports are sourced from the Access database. To query for TSP (Transit Signal Prioritization), load this query into the "Definition Query" tab under Properties: \\mtanas\sfmtagis\04_GeoTools\Queries\TSP.exp| E.
