aceacedey/Kolkata_Data_PMC_paper_TrafficCountEstimationUsingCrowdSourcedTrajectory: Raw GNSS vehicle trajectory data are added

The raw GNSS trajectory data at the Webel intersections (experimental site) are added. These trajectory data are used to estimate link counts. These data were missing in the previous release, v0.

P.S. - All the .txt files contain raw GNSS data with timestamps recorded in GMT. Hence, all the timestamps in .txt files need to be adjusted by adding 5 hours and 30 minutes (GMT +5:30), which is the Kolkata, India, time zone.

The timestamps in the .csv files (files that contain link counts and leader-follower headway) are local time as they are recorded in Kolkata.

In the raw GNSS data that contains .txt files, the file name starting with something like "ds1 L..." stands for the leader trajectory of dataset 1, and "ds1 F..." stands for the follower trajectory of dataset 1. Similarly, we have recorded multiple such leader-follower trajectories.
