Hi folks,

i'm having a problem with transform a dataset. i have a dataset, it has a 15-mins speed profile on a road for both weekday and weekend. now i want to map this speed profile onto the road for 1 year. example of the dataset is as follows, it's in CSV file format, (first 96 is for weekday, later 96 is for weekend)

32.61712_29.23591_24.84628_22.84434_30.59529_28.76819_35.03523_.......


the final table i want to generate from perl is:
link_number time_interval day of the week speed
1 1 1(monday) 32.61712
1 2 1(monday) 29.23591
...
1 97 2(tuesday) 32.61712
.....

anyone has idea how to do this ? i'm thinking to use the PERL read the csv file as array and use conditional statement according to 'day of the week' to load either first 96 or later 96 speed value. but i don't know how to write this, any ideas ?

thanks, Simon
