FOREWORD

Vehicles and roadways of the future will employ advanced communications technologies to facilititate applications to make driving safer, more efficient, and more environmentally friendly. The safety benefits will largely be achieved by communicating relevant safety information to the driver. The Human Factors for Connected Vehicles research program is focused on understanding, assessing, planning for, and counteracting the effects of signals or system-generated messages that take a driver’s eyes off the road (visual distraction), the driver’s mind off the driving task (cognitive distraction), and the driver’s hands off the steering wheel (manual distraction). The overall goal of this research is to support the introduction of this technology as a benefit to all transportation users.

The research described in this report provides some intial design guidance for vehicle-to-infrastructure (V2I) safety messages as well as some limited guidance for vehicle-to-vehicle systems. This report primarily uses existing transportation safety research, as well as research from related domains. This information can be used by connected-vehicle system designers and other State transportation department personnel to develop and implement V2I applications, to make sure these systems work effectively and safely within a larger vehicle-to-infrastructure, vehicle-to-vehicle, and vehicle-to-device environment. In this way, these findings will help make the interaction of roadway and vehicle systems safer, reduce the likelihood of crashes and injuries, and increase safety for all roadway users.

16. Abstract

This report is part of the Human Factors for Connected Vehicles (HFCV) research program, whose goal is to minimize driver workload by eliminating connected vehicle (CV) device-related distractions. The research described in this document is part of an effort to develop initial design guidance for vehicle-to-infrastructure (V2I) safety messages provided using driver-infrastructure interfaces and driver-vehicle interfaces. Existing HFCV research, in addition to research from related domains, was used to develop this preliminary design guidance. The target audiences for this information are CV system designers and other State transportation department personnel involved in the development and implementation of V2I applications that provide safety information. The design topics are divided into two sets. The first set is composed of general topics providing background information and covers issues that apply across multiple V2I applications. The second set includes topics focusing on specific V2I applications. The general objective of the guidance information is to assist in the coordination of V2I and vehicle-to-vehicle displays and messages to safely support driver information needs and decision making. This information may serve as a resource for the development of guidelines that address V2I system-related human factors design issues in future versions of NCHRP 600: Human Factors Guidelines for Road Systems.
