Where can I find information on the condition of the road?
Road conditions, construction and similar information can be found at:
http://511.ky.gov or by calling 511 in Kentucky.
What is this web page used for?
The Roadway Weather Information System provides information to the Cabinet's maintenance engineers to assist them in deciding what method and what type of chemicals should be used to remove snow and ice. Other users of the system include the National Weather Service, local meterologists, public schools and universities.
What is the difference between "Last Updated" and "Last Sample"?
Last updated is the time at which the graph was re-drawn. This time should not be more than a few minutes old. Last Sample is the time at which the system called the weather station in the field and retrieved the data. This time will vary according to the need for current data.
What is dewpoint?
Dewpoint is a relationship between relative humidity and temperature. It is the temperature at which condensation (dew, frost) occurs. It is useful to predict overnight low temperature and temperature changes during precipitation. A large difference between the dewpoint and air temperature indicates low humidity. If the dewpoint is equal to the air temperature the humidity is 100%
What is solar radiation?
Solar Radiation is sunlight intensity. It varies from 0 to about 800 watts per square meter. This measurement is useful for measuring cloud cover and predicting pavement temperatures.
What is wetness?
The wetness graph is the output from a simple sensor that can detect dew, sleet or drizzle before it shows up on the precipitation sensor. There is no scale to the data, it is a wet-dry condition sensor.
What are the Surge Protector, Humidity, and Battery lights for?
These indicators are for diagnostic purposes.
Why are some indicators "greyed out"?
If an indicator is greyed out it means that the associated sensor has failed.
How often is the data collected?
Data can be collected as frequently as needed. Because each collection requires a long distance telephone call, data may not be collected as frequently during the summer months.
The information is too complicated!
As we develop the system users will learn what conditions to look for when making road maintenance decisions. After defining these conditions the system can be programmed to display alarms, send emails or call pagers to alert the road crews of deteriorating road conditions.
Why is there no "pavement condition" sensor?
We plan on adding pavement condition in future years as non-proprietary technology becomes available.
What new sensors are planned?
A video camera will probably be standard on all stations. We are currently testing various cameras for this purpose.
Will you share your weather data?
Certainly. The raw data is available via FTP. The data is stored in comma separated ASCII. Contact us for more information.
