Allows road wear

Allows tire wear

Allows brake wear

Allow road suspension

Allow shoulder suspension

Allows the sand paper effect

Allows wind blown dust suspension

Allows dust and salt to be drained from the road

Allows dust and salt to be sprayed from the road



Allows retention of wear particles on the surface due to surface wetness. 1 is linear, 2 is exponential, 0 is no retention

Uses the observed moisture to determine the surface retention

1 = time scale, 2 = Penman Omstedt, 3 = Penman modified, 4 = energy balance, 5 = energy balance with ice

Allows spray from the road surface. Must be 1 for dust and salt to be sprayed

Sets the method for describing the surface humidty. 1 is linear, 2 is exponential



1 = hourly means, 2 = daily means, 3 = daily cycle

1 = save data, 2 = save plots, 3 = save both, 0 = none



Use the street canyon dimensions to shadow the road

Use the street canyon dimensions to produce long wave radiation at the atmospheric temperature



Allows salting, either from the input data or by rule

Allows sanding, either from the input data or by rule

Allows ploughing, either from the input data or by rule

Allows cleaning, either from the input data or by rule

Allows salting by rule (over rides the input data values)

Allows sanding by rule (over rides the input data values)

Allows ploughing by rule (over rides the input data values)
