Trajectory Conversion Analysis (TCA) Program
•Open Source Python program
•Inputs
–Vehicle Trajectory Files (Actual or Simulated)
–RSE locations and range
–Parameters for snapshot generation & transmission
•Outputs
–Snapshots generated and transmitted to RSEs
–Snapshots discarded for buffer overflow or RSE gap
–Probe segment number changes
The TCA program is an open source program written in Python.  It can be configured to model a variety of snapshot generation / transmission policies and PSN change policies.  Given a set of vehicle trajectories and RSE locations, the TCA produces a set of snapshots that would have generated, transmitted, and received by RSEs following the given policies.  The program also reads parameters defining the buffer management policy, and models the deletion of snapshots when buffer size is exceeded.

With different input parameters, the TCA can model direct transmission of snapshots to a central location with cellular communication rather than to individual RSEs.  TCA does not model transmission failures or losses.

TCA documentation and sample input files are included in the data environment.
