average vehicle speed shall be calculated as follows:

              where:

              Nk is the total number of samples of the urban and expressway shares.

3.1.4. Calculation of per speed bin
              3.1.4.1. Calculation ofper speed bin (for analysis with 4-phase WLTP)

              The 95th percentile of the (v ×apos) values shall be calculated as follows:

              The (v ×apos)i,k, values in each speed bin shall be ranked in ascending order for all datasets with ai,k > 0.1m/s2 and the total number of these samples Mk shall be determined.

              Percentile values are then assigned to the (v ×apos)i,k values with ai,k > 0.1 m/s2 as follows:

              The lowest (v ×apos) value gets the percentile 1/Mk, the second lowest 2/Mk, the third lowest 3/Mk and the highest value (Mk/Mk = 100 %.)

              is the value, (v ×apos)i,k with j/Mk = 95 %. If j/Mk = 95 % cannot be met, shall be calculated by linear interpolation between consecutive samples j and j+1 with j/Mk < 95 % and (j+1)/Mk > 95%.

              The relative positive acceleration per speed bin shall be calculated as follows:

              where:

RPAk     is the relative positive acceleration for urban, rural and motorway shares in [m/s2 or kWs/(kg*km)]

Mk       is the sample number for urban, rural and motorway shares with positive acceleration

Nk       is the total sample number for urban, rural and motorway shares

t       is a time difference equal to 1 second

3.1.4.2. Calculation of per speed bin (for analysis with 3-phase WLTP)
              The 95th percentile of the (v ×apos) values shall be calculated as follows:

              The (v ×apos)i,k values in each speed bin shall be ranked in ascending order for all datasets with ai,k > 0.1m/s2 and the total number of these samples Mk shall be determined.

              Percentile values are then assigned to (v ×apos)i,k values with ai,k > 0.1 m/s2 as follows:

              The lowest (v ×apos) value gets the percentile 1/Mk, the second lowest 2/Mk, the third lowest 3/Mk and the highest value (Mk/Mk = 100 %.)

              is thevalue, with j/Mk = 95%. If j/Mk = 95% cannot be met, shall be calculated by linear interpolation between consecutive samples j and j+1 with j/Mk < 95% and (j+1)/Mk > 95%.

              The relative positive acceleration per speed bin shall be calculated as follows:

where:
RPAk     is the relative positive acceleration for urban and expressway shares in [m/s2 or kWs/(kg*km)]

Mk       is the sample number for urban and expressway shares with positive acceleration

Nk       is the total sample number for urban and expressway shares

t       is a time difference equal to 1 second

4. Assessment of trip validity
              4.1.1. Assessment of per speed bin (with v in [km/h])

              If and
              is fulfilled, the trip is invalid.

              If and

              is fulfilled, the trip is invalid.
