The number of lanes and the particular eccentricity for each lane are calculated automatically from the input of the road way width (rww) given in the section SDL of the load definition using a default width of notional lanes of 3m (just one input value for all lanes). However, these settings could be adjusted by the user.
Note: The remaining area (i.e. road way width minus width of all notional lanes) is considered automatically and doesn't need to be defined by the user.
The lanes are distributed onto the road way from left to right, whereas using option "Mirror" will apply them also starting from the right side (default setting "Yes"). In the stage calculation of RM Bridge these two situations will then be superposed with each other.

| Tandem-System |
Axle distance and intensity of the tandem-system (i.e. load per axle) for the notional lanes 1 to 3 can be given.
Consider tandem (Yes/No) defines whether the Tandem-System shall be considered or not (upper table, top right).
|
| UDL |
The area load intensity for the notional lane 1 and all other lanes (including remaining area) can be given. |
| Factors |
The factors for the tandem-system, the UDL on the notional lanes and the UDL on the remaining area can be adjusted. |
| Pedestrian load |
Consider pedestrian load (Yes/No) defines whether the pedestrian load shall be considered or not.
Intensity left/right and eccentricity left/right defines the intensity and the eccentricity of the linear distributed load on the left and right side of the roadway.
