BSM (+BMM) Data Emulator Dynamic Interrogative Data Capture (DIDC) Assessment Report: Impacts of DIDC

The objective of the Dynamic Interrogative Data Capture (DIDC)algorithms and software is to optimize the capture and transmission of vehicle-based data under a range of dynamically configurable messaging strategies. The key hypothesis of DIDC is that using a well-constructed DIDC approach will have a lower risk of privacy issues and higher effective measures estimation along with a reduced data transmission load than comparable non-DIDC alternatives. The DIDC method will go through two rounds of testing using a simulation network: the first round of experimentation will study DIDC concepts and the second round will compare DIDC to other message types. The purpose of this report is to describe the testing method and results from comparing the DIDC messaging concept with current message types. This is the second phase of DIDC testing conducted in the BSM Data Emulator project. The first phase of DIDC testing, the proof of concept, was completed in January 2016 and is described in a separate test plan and final report. This second phase of testing compared the measures estimation capabilities, data communication load, and re-identification efforts of the DIDC concept to Basic Safety Message (BSM), Probe Data Message (PDM), and the European Union Cooperative Awareness Message (CAM).
