Planning Guidance for the Installation and Use of Technology Devices for Transportation Operations and Maintenance

ENTERPRISE Transportation Pooled Fund Study

CCTV Guideline 3 - Weather Verification

Purpose: To allow maintenance dispatchers and traffic control personnel to verify weather conditions on the roadway, either to guide traveler information dissemination or to dispatch operations.

Engineering judgment should be used to assess potential implications that may result from the installation of CCTV. This planning guidance does not mandate the use of CCTV.

1. The location typically encounters at least 10 weather events each season.

AND

2. Weather events have a significant impact to travelers at this location (due to such circumstances as either: local terrain, lack of alternate routes, winding or steep routes), and it is a location that travelers are frequently concerned about.

AND

3. If there are

• No nearby weather sensors reporting real-time conditions; or
• No regular manual observations and repots of visibility, precipitation, or pavement temperatures, or
• Nearby weather sensors would be enhanced through the capability of visual observation.
  

Partial Guideline Criteria:
If #1 And #3 above are met, the guideline is considered ‘Partially Met’. If one or more additional purposes are partially met at this location for this device, the device should be considered.
