Advanced Messaging Concept Development (AMCD) Project Vehicle-to-Infrastructure Program: Final Report

DTFH6114H00002
The Advanced Messaging Concept Development (AMCD) Project objective was to evaluate the ability of connected vehicles to generate, and infrastructure to collect, Basic Safety messages (BSM), Probe Data Message (PDM), and Basic Mobility Message (BMM) alternatives using cellular and DSRC communications while employing message control strategies in real-world driving conditions for non-safety-critical applications. These three message schemes represented potential alternatives for transferring data from equipped vehicles to the infrastructure. Such data transfer is intended to enable a broad array of Vehicle-to-Infrastructure (V2I) applications which may be used to improve operations. AMCD implemented the three messaging schemes on the Virginia Connected Corridor with the aim of validating efficacy and characterizing their associated behavior. The schemes were exercised in live traffic using ten instrumented vehicles and an emulated traffic operation center interface where the experimenters manipulated the various message control parameters while measuring the resulting message traffic. Results support the feasibility of advanced V2I messaging and demonstrate potential advantages of a flexible, multi-threaded message scheme. A number of recommendations are provided with the aim of further improving V2I messaging capabilities and leading to implementation of advanced messaging with infrastructure applications to assess the operational value in deployment.
