Helping finding ATD GIS Data - Sara from APD

[jaime-mckeown]

Sara is looking for the following GIS data sets:

• Traffic Signals
• Stop Signs
• Pedestrian Signs
• Railroad Crossing Signs

[jaime-mckeown]

Sent her the following:

Traffic Signals:

• Our traffic signal data is only in AGOL, and it consists of Traffic and Pedestrian Signals. There is a Signal Status field where you can filter out only Turned-On signals and a SIGNAL_TYPE field for Traffic/PHB.
• https://austin.maps.arcgis.com/home/item.html?id=e6eb94d1e7cc45c2ac452af6ae6aa534

For signs data, ATD does not currently have current and accurate signs GIS data. We are working on an RFP right now to do a complete signs data collection, which will be the start of a maintenance dataset. There are a couple layers that may be helpful though.

Stop Signs:

• Stop Lines are in TRANSPORTATION.markings_short_line in GISDM and AGOL, filter by the SHORT_LINE_TYPE field. According to Christina, not all stop signs have stop lines associated with them, but this would cover most.
• There is an old Stop Signs layer in AGOL that may help cover some of the places where there may not be a stop line.
• https://austin.maps.arcgis.com/home/item.html?id=3ec39e5e70394ce59ff83454c3c1cab2

Railroad Crossing Signs:

• Railroad crossing markings are in TRANSPORTATION.markings_specialty_point in GISDM and AGOL, filter by SPECIALTY_POINT_TYPE of Symbol and SPECIALTY_POINT_SUB_TYPE of Railroad Crossing.

Pedestrian Signs:

• I don’t know if this will help, but the TRANSPORTATION.markings_short_line in GISDM and AGOL does have Crosswalks and School Zone Lines under the SHORT_LINE_TYPE field.
• Also, the TRANSPORTATION.markings_specialty_point in GISDM and AGOL has Pedestrian marking types.

I also sent her a link to ATD Geospatial's GitBook for help deciphering the markings specialty point types and subtypes.

Double checked with Christina on the layers before sending the information above to Sara.
