What is link_no? Where are the commas in your Comma Separated Values? Time_interval seems to be a 15-minute part of a day, right? If you want to keep the data structure as simple as possible you can still store all data into one array, just add 96 to the index if you want to access the weekend data.

For a clean maintainable solution you have to use a multi-dimensional array, something like this:

#Store an entry:
$speed[1][1]['weekday']= 32.61712;
#or when you load values from a CSV file (I assume all values on one l
+ine:
my $line=<csvfile>;
my @speeds= split $line;
my $link_no=1;
my $i=1;
my $day='weekday';
foreach (@speeds) {
  $speed[$link_no][$i++][$day]= $_;
}

If you want to have each day in the database instead of only data for 'weekday' and 'weekend', you can still use above and then either copy the 'weekday' data to the 'monday', 'tuesday' slots or copy only the link (i.e. $speed[$link_no][$i++]['monday']= $speed[$link_no][$i++]['weekday'];, which would share the data, i.e. if you change data in the 'weekday' set, you also change it in the 'monday' set)
