MOUS_ICO Popup menu: Traffic data

This dialog box has a different structure than the others in Novapoint Noise. The box consists of two parts; one selection part and one data part. The selection part constitutes the left part of the dialog box and gives you the opportunity to select from a tree structure with the main subject's Traffic, Speed, and Percentage of heavy vehicles. Branches for each of the subjects may be expanded by clicking the subject name or + to the left of the subject name. Correspondingly the branches may be hidden by clicking the subject name or - to the left of the subject name. In the data part, constituting the right and biggest part of the dialog box, the entered values for the relevant combination of section and subject are shown. In principle, this window shows the entire road, divided into sections by where there are changes in traffic volume, speed level, and/or percentage of heavy vehicles. Each such section is defined by its From and To chainages and is homogenous concerning thee subjects shown in the data part. The user may choose which data to be shown in the data part by ticking the box right in front of the subject name in the selection part. Data is shown only for the subjects where there is a tick in the box in front of the subject name.

Entering data for the different subjects is more closely described below. The user may enter or edit values in the white fields in the data part by clicking in the relevant field.

During calculation, the 24h values are used to calculate Lequ and Lmax, the Night values to calculate Lnight and Day, and Evening and Night to calculate Lden.

The alternative 75/15/10 means that 75% of the daily traffic is in the daytime, 15% in the evening, and 10% at night. If one of the predefined distributions is selected, the values in the data fields Day, Evening, and Night are calculated automatically. If the alternative Custom is selected in the Distribution field, the user can enter numbers in the data fields Day, Evening, and Night. If this possibility is chosen, the sum in the field 24h is adjusted to the sum of the three other fields. If one then changes the value for 24h, the values for Day, Evening, and Night are changed accordingly.

By entering ADT=0 for a section, the section is not included in the calculation. This is useful if, e.g., part of the road is in a tunnel.

Speed for light and heavy vehicles are entered as average for 24h. If the speed Varies over 24 hours, it may in addition be stated separately for each of the time periods Day, Evening, and Night. The user may switch between No and Yes in the field Varies, by double-clicking in the field or pressing <Space> when it is selected.
