- Initial baseline schedule must include the activities and milestones needed to transition RWIS station polling to the new system, test and verify station polling quality, user training, and retirement of the old polling system, and must include a high-level timeline projection of all other subsequent activities.
- RWIS polling system user interface:
- The system must:
• support access for 300+ concurrent users.
• have an interactive GIS map with individual layers that can be turned on or off; layers must include current winds, air temperature, pavement temperature, bridge temperature, dew point, and precipitation.
• have current station views which show all the current data from a selected station
• display historical graphs and tables showing data from a selected date/time period and station; a user must be able to retrieve all data collected from any non-image data type
• have an export tool for downloading historical data from a selected date/time period and station into a text file, comma separated values, and/or Microsoft excel spreadsheet.
• provide a visual alert when there is missing and/or errant data
• provide complete station configurations, including all sensor configurations for use by the state department project manager, their designee, and/or their RWIS maintenance service provider.
• provide user interface through a hosted, web-based, device-agnostic interface.
• be accessible via a mobile application interface, such as tablets and/or smartphones.
• The system data must be displayed in English units
- RWIS polling system data:
• The system must collect and store the following data types from each station, including but not limited to:
1. Air temperature
2. Surface temperature – up to 4 locations per station
3. Subsurface temperature
4. Deep probe temperature – 15 locations per station
5. Precipitation type
6. Precipitation rate
7. Precipitation intensity
8. Wind average speed
9. Wind gust speed
10. Wind direction
11. Visibility
12. Dew point temperature
13. Relative humidity
14. Surface condition
15. Surface friction
• The system must communicate with all national transportation communications for its (intelligent transportation systems) protocol (NTCIP) 1204 compliant environmental sensor stations
• The system must be able to communicate with the stations through a variety of communication methods, including cellular via VPN, cellular based connections, DSL, leased lines, and/or department fiber optic networks
- RWIS polling system reports, exports, and data access
• The system must produce data feeds that are JSON, GEOJSON, formatted xml, and/or GIS rest for both real-time and historical data.
