TCA-A 2.3 Overview ============================ The Trajectory Conversion Algorithm-Aimsun (TCA-A) Software is designed to test different strategies for producing, transmitting, and storing Connected Vehicle information. The TCA-A runs with the Aimsun tool using real-time simulation vehicle information, roadside equipment (RSE) location information, cellular or event region information and strategy information to produce a series of snapshots that a connected vehicle would produce. Vehicles can be equipped to generate and transmit Probe Data Messages (PDMs), Basic Safety Messages (BSMs), Cooperative Awareness Messages (CAMs) or ITS SPOT messages which can be transmitted by Dedicated Short Range Communication (DSRC) and/or via cellular. The TCA-A program version 2 build 3 or 2.3 includes simulated communication disruptions between vehicles and roadside equipment. As soon as a vehicle equipped to transmit via DSRC is in range of a RSE, it will download all of its snapshot information directly with a probabilistic uncertainty of the data being lost. Similarly, if the vehicle is equipped to transmit via cellular, it will download all its snapshot information directly but those snapshots might be lost or delayed due to user-defined loss rate and latency. In TCA-A 2.3, BSMs and PDMs can also be made to transmit at user-defined intervals.

Configuration ------------------------- The TCA software can run on most standard Window or Linux based computers with Pentium core processors, with at least two gigabytes of RAM and at least 100 MB of drive space. Performance of the software will be based on the computing power and available RAM in the system. Larger datasets can require much larger space requirements depending on the amount of data being read into the software. The TCA software application was developed using the open source programming language Python 2.7 (www.python.org). The application requires Python 2.7 or higher to run. Note that Python 3.0 is a change from Python 2.X language and will not run the DMA performance measurement application. Python versions 2.7.X – 2.9.X will work. The application can be run on Windows, Linux, or Mac operating systems. Python is installed by default on many Linux and Mac operating systems. Documentation ------------- The TCA-A 2.3 software is packaged with Word based User Guide "The Trajectory Convertor Algorithm-Aimsun 2 3 User manual.doc" that contains all information about background purpose, benefits, objectives, inputs/outputs, how to run the software and requirements for the software.
