Creating safer roads for cyclists.

About B2V

Starting in 2017, Tome has been working on various projects within a larger program related to open and collaborative Bicycle to Vehicle (B2V) safety. Tome has engaged with multiple companies from the cycling, automotive, and smart city industries in order to find solutions to create communication between Vulnerable Road Users (VRUs) and vehicles.

2019 B2V Workshop (Detroit, MI)

Overview

Over 100 attendees from 65 organizations representing the bicycle and automotive industries, academia, and government teams met at a workshop organized by Tome Software in Detroit, Michigan on August 13 and 14, 2019.

Ford and Tome provided live demonstrations of B2V technology opportunities. The purpose of the meeting was to discuss advanced vehicle technologies and connectivity in relation to bicycle safety. The conversation also embraced topics of concern for other vulnerable roadway users such as pedestrians and persons using scooters.

Key Findings

Key findings included user experience requirements and prioritization for drivers and cyclists (including device charging requirements), technical common ground between the automotive and cycling industry on Bluetooth 5.0, and shared understanding of key vulnerable use cases.

Tome was able to show that Bluetooth 5.0 is an effective way to represent the VRU within a traditionally vehicle-centric safety context. Previously, it was widely assumed that a dedicated V2V messages required specific V2V RF components. This demonstration showed that V2V messaging could be accomplished with standard components.

Next Steps

Technical development is needed on the shared message sets for communication between bicycles and vehicles. Much of the groundwork has been completed by the automotive V2V standards. However changes will be needed to apply for cyclists and other VRU categories.

Additionally, a continued engagement between auto and bicycle industries is also needed to further drive standards and keeping the focus on VRU needs. Tome is working with the B2V advisory board member companies on formally creating or joining a consortium and contributing standards through SAE and other appropriate standards groups.
