When the turn signals were activated, the blind zone was extended by a time based on the closing speed of the approaching vehicle. The V2V equipment determined blind zone was different for each side of the vehicle evaluated in this study (shorter on right side). The prototype V2V equipment was observed to be capable of tracking potential BSW/LCW threats, but occasionally the equipment would not recognize that a vehicle was in the V2V equipment determined blind spot warning zone due to the equipment’s error in estimating the lateral range between the vehicles. This report documents NHTSA’s test track research performed to support development of objective test procedures to evaluate the blind spot warning/lane change warning (BSW/LCW) safety application of commercial vehicles with vehicle-to-vehicle (V2V) equipment. Commercial Connected Vehicle Test Procedure Development and Test Results - Emergency Electronic Brake Light (DOT HS 812 327).In applying this methodology, it is assumed that all heavy vehicles are equipped with the three selected V2V safety applications and that all other motor vehicle body types (e.g., passenger cars,motorcycles, etc.) are equipped with V2V vehicle awareness devices that transmit basic safety information to heavy vehicles.

The methodology relies on target baseline crash populations obtained from the 2011-2013 General Estimates System crash database driver/vehicle/application performance data from a National Advanced Driving Simulator study naturalistic driving data from the Integrated Vehicle-Based Safety System field operational test and on the Safety Impact Methodology tool that simulates the basic kinematics of driving conflicts and driver/vehicle response. The report also describes the application of this methodology and the resultsfor three selected crash warning applications: intersection movement assist, forward crash warning, and blind spot/lane change crash warning.The safety benefits are projected in terms of annual reductions in the number and comprehensive cost of police-reported crashes that involved multiple vehicles, including at least one heavy vehicle.
This report presents a general methodology to estimate the crash avoidance effectiveness of vehicle-to-vehicle (V2V) safety applications forheavy vehicles and project their potential annual safety benefits.
