To catch someone in a bomb blast just by their daily scheule the person would have to travel past the same place each day within a space of a few seconds. Very unlikely to happen in something like a train. Certainly ain't going to happen in a car. Terrorists can use daily schedules as a general guide to when a target is arriving, but that has to be backed up by other information, like actually observing the target's arrival on the day of the blast to allow a hit.
