Public Transport Driver Identification System Using Histogram of Acceleration Data

Algorithm 1

Inactive-period filtering algorithm.

Input:acceleration acc_raw,

latitude lat,

longitude lng

Output:acceleration (without inactive period) acc

1: for each  acc_raw  do:

2:Initialize next_lat to next five-second of lat

3:Initialize rateOfChange_lat to (next_lat - lat)/lat

4:Initialize next_lng to next five-second of lng

5:Initialize rateOfChange_lng to (next_lng - lng)/lng

6:if  rateOfChange_lat is zero and rateOfChange_lng is zero do:

7:remove acc_raw

8:end if

9:end for

10:return acc_raw as acc
