7	Basic Safety Message (BSM) Fundamentals Connected V2V safety applications are built around the SAE J2735 BSM, which has two parts BSM Part 1: Contains the core data elements (vehicle size, position, speed, heading acceleration, brake system status) Transmitted approximately 10x per second BSM Part 2: Added to part 1 depending upon events (e.g., ABS activated) Contains a variable set of data elements drawn from many optional data elements (availability by vehicle model varies) Transmitted less frequently No on-vehicle BSM storage of BSM data The BSM is transmitted over DSRC (range ~1,000 meters) The BSM is tailored for low latency, localized broadcast required by V2V safety applications
8	Mobility Programs: BSM Assessment Activity Assess the extent to which the BSM supports or enables mobility applications To what degree is a DSRC-based BSM Part 1 message critical to realizing transformative benefits from mobility applications? What key elements of BSM Part 2 or other vehicle-based data might be needed? Where and how often? Can other messages tailored for cellular communication augment a DSRC-based BSM? As we add data from mobile devices and fixed sensors, how much improvement do we see in application effectiveness?
9	Role of BSM Part 1 Via DSRC In Support of Mobility Applications BSM Part 1 via DSRC provides the vehicle data needed to support a few mobility applications that require low latency and localized broadcast exchange Cooperative Adaptive Cruise Control Queue Warning These applications will likely be successful wherever DSRC-capable roadside infrastructure (RSEs) is deployed Key intersections Major interchanges
10	Key Elements of BSM Part 2 Needed for Mobility Applications BSM Parts 1 and 2 via DSRC provides the vehicle data needed to support some localized mobility applications
11	Using Cellular Messages to Augment BSM for Mobility Applications
12	Data and Communications Question
13	Summary of Initial Assessment: BSM and Mobility Applications The Mobility Program (DCM/DMA) is currently engaged in a research program intended to identify: Key Part 2 and other vehicle-based data elements required by high-priority mobility applications Required frequency and latency Likelihood of OEMs to make this data available publicly Requirements for data storage on vehicles Identify potential targeted use of triggers to reduce data redundancy In conjunction with the safety/policy program, identify business and financial models to support deployment Examine vehicle data needs in light of additional data from mobile devices and fixed sensors
14	Mobility Program: Schedule of BSM-Related Next Steps Updates to BSM Role Assessment Research May 2012: Application ConOps Update September 2012: BSM Data Analysis Update May 2013: Impacts Assessment Update Specific Stakeholder Engagement to Date OEM Engagement – through VIIC AASHTO Engagement – through Pooled Fund Study/AASHTO Working Group Policy Workshop Presentation Specific BSM Data Analysis Obtaining Safety Pilot Model Deployment Data Will Conduct Mobility-related Technology Testing
