Autonomous Road Weather Systems - A Cost-effective Way to Increase Monitoring Points on a Road Network
Accurate weather information plays an
important role in road trafficmanagement
allowing operators to warn drivers of poor
conditions, and take precautionary actions
such as reducing speed limits or gritting
roads. For road weather a combination of
forecast information and empirical data
collected from roadside outstations is used
to anticipate potential problems which
might affect road safety or traffic flow.
Forecasts have improved over the years
but they are still not 100% reliable and so
verification of actual conditions through
site measurement is vital.
