| Abstract | The objective of this research project was to enhance and test the platoon identification and accommodation (PIA) system developed by Texas Transportation Institute (TTI) researchers in an earlier research project. The PIA system consists of off-the-shelf hardware and custom software for providing intelligent control at isolated traffic signals. To achieve project objectives, TTI researchers added a software classifier to replace the hardware classifier needed by the original system, added a new module for communication with TS-2 cabinets via serial ports on enhanced bus interface units, extended the system to provide platoon identification and accommodation on both arterial directions, and added real-time performance measurement and adaptive features. Implementation of these enhancements required TTI researchers to re-engineer the original system software. The enhanced system was tested in the lab using cabinet-in-the-loop simulations and then field-tested at two locations in Texas. This report documents the work conducted by TTI researchers in this project. |
