Development of Wireless Message for Vehicle-to-Infrastructure Safety Applications 2018-01-0027
This paper summarizes the development of a wireless message from infrastructure-to-vehicle (I2V) for safety applications based on Dedicated Short-Range Communications (DSRC) under a cooperative agreement between the Crash Avoidance Metrics Partners LLC (CAMP) and the Federal Highway Administration (FHWA). During the development of the Curve Speed Warning (CSW) and Reduced Speed Zone Warning with Lane Closure (RSZW/LC) safety applications , the Basic Information Message (BIM) was developed to wirelessly transmit infrastructure-centric information. The Traveler Information Message (TIM) structure, as described in the SAE J2735, provides a mechanism for the infrastructure to issue and display in-vehicle signage of various types of advisory and road sign information. This approach, though effective in communicating traffic advisories, is limited by the type of information that can be broadcast from infrastructures. The new BIM provides additional infrastructure data needed to support dynamic vehicles based safety applications and also leverages existing SAE J2735 data elements. By including data containers specific to other applications, the proposed BIM framework can be extended to support additional safety applications without compromising on backward compatibility to other connected vehicle infrastructure systems.
