Likewise, the data showed 22 and 25 percent of the police-reported non-fatal road departure and opposite direction crashes, respectively, occurred at 72.4 kph (45 mph) or less. NHTSA published a notice on April 28, 2020, seeking public comment on the information collection aspect of the consumer market research. Three light vehicles and three rear-end crash scenarios were used for this evaluation. [170] Are these regions appropriate to include, and if so, what is the appropriate method by which to include them? When the Side Blind Zone Alert technology was combined with an earlier generation technology, GM's Lane Change Alert, the corresponding effectiveness increased to 26 percent. 62. Also, Bosch stated that the specialized tests required to address the Agency's concern may not be truly representative of all real-world driving situations that the system encounters. The Agency agrees with BMW that FCW and AEB are interrelated and is thus proposing to assess the presence of an FCW alert as an integral component of the CIB test. for DBS) and most performance criterion. The Agency also planned to use these test results to determine the feasibility of increasing the stringency of NCAP's LVD test. How many validated clues are there for HGN testing? 3. What research data exist that substantiate effectiveness of these interventions? 190. 121. Start Printed Page 13469 NHTSA is proposing to use its published draft test procedure titled, Blind Spot Intervention System Confirmation Test,[97] Several commenters offered additional suggestions for ways NHTSA could expand the BSW test procedure. This path must be maintained, and the test speed must be achieved, at least 61.0 m (200 ft.) prior to the start gate. Test reports related to NHTSA's CIB characterization testing can be found in the docket for this notice. i.e., For this reason, the Agency used the GVT in its characterization study for CIB testing at higher speeds. The crash scenarios referenced for the FCW/CIB/DBS target population are those that comprise the subset of the 84 mutually exclusive pre-crash scenarios analyzed by VOLPE (Report No. e.g., Why or why not? Conversely, Delphi, ASC, and MTS commented that some of the more robust systems that are currently available should be able to comply with the narrower specification. Lastly, many commenters recommended harmonizing test procedures, test requirements, test devices, and the like with other government agencies and standards development organizations, such as the International Organization for Standardization (ISO), SAE International (SAE), and other consumer information programs worldwide. i.e., However, the inherent granularity of a points-based system may cause consumer confusion if conveyed in addition to another, coarser, communication rating concept, such as stars or medals. i.e., LVMThe SV encounters a slower-moving POV directly in front of it on a straight road. Statistics of light-vehicle pre-crash scenarios based on 2011-2015 national crash data [242] Start Printed Page 13485 At this time, the Agency believes the traditional dashed and solid lane marking tests would be sufficient. (42) The Agency's proposal to (1) consolidate its FCW and CIB tests such that the CIB tests would also serve as an indicant of FCW operation, (2) assess 14 test speeds for CIB (5 for LVS, 5 for LVM, and potentially 4 for LVD), and (3) assess 6 tests speeds for DBS (2 for LVS, 2 for LVM, and potentially 2 for LVD), would result in a total of 20 unique combinations of test conditions and test speeds to be evaluated for AEB. [235] 249. 32. (26) Should the Agency consider performing PAEB testing under dark conditions with a vehicle's upper beams as a light source? has no substantive legal effect. Overlap is defined as the percent of the vehicle's width that the pedestrian would traverse prior to impact if the vehicle's speed and pedestrian's speed remain constant. Having said that, the Agency sees merit in using available real-world data, specifically target populations, to determine which ADAS technologies should be considered for inclusion in the program. In this notice, the Agency is seeking feedback on the appropriateness of the test scenarios, test conditions, test condition variants, and number of trials within each test variant for the four proposed technologies (PAEB, LKS, BSW, and BSI) discussed in this RFC, in addition to the four technologies currently included in NCAP. In its response to NCAP's December 2015 notice, Bosch provided similar insight. i.e., The American Automobile Association (AAA)[119] In an effort to correlate rating system weights directly with potential real-world safety benefits, too little weight may be assigned to technologies that have lower target populations (such as those for Blind Spot Detection) compared to technologies that have much higher target populations (such as those for Forward Collision Prevention). While supporting an overall rating, many commenters stated that the individual ratings for the crashworthiness and ADAS programs should be part of the new ratings system and be made available to consumers. However, as discussed earlier, the Agency believes that active safety technologies are more effective than warning technologies. In the Agency's December 2015 notice, NHTSA discussed a series of point values for the ADAS technologies at that time. Commenters stated that the public comment period was inadequate for purposes of responding because of the complexity of the program described in the RFC, and claimed that the technical information supporting the notice was not sufficient to allow a full understanding of the contemplated changes. Second, this RFC fulfills portions of the requirements in Section 24213(b) of the Bipartisan Infrastructure Law that mandates the Agency publish a notice, for the purposes of public comment, to establish a means for providing consumer information relating to advanced crash-avoidance technologies within one year of enactment that includes: (1) An appropriate methodology for determining which advanced crash avoidance technologies should be included in the information, (2) performance test criteria for use by manufacturers in evaluating those technologies, (3) a distinct rating system involving each technology, and (4) updating overall vehicle ratings to include the new rating. Historically, it has also been a difficult scenario for forward-looking sensing systems to address, especially at high vehicle speeds. [11] identified that 42 percent of lane departure crashes ( However, in the same protocol, Euro NCAP also specifies a range of lateral velocities from 0.3 to 0.6 m/s (1.0 to 2.0 ft./s) be used to represent unintended lane e.g., The Agency also acknowledges that these test conditions must be repeated for multiple test speeds and lighting conditions, which inherently imposes additional test burden. (49) The Agency requests comment on the use of the GVT in lieu of the SSV in future AEB NCAP testing. For model year 2018 vehicles, 38.3 percent were equipped with FCW and 30.1 percent were equipped with LDW. To supplement these initial findings, additional LKS testing has since been conducted and is undergoing analysis. As beneficial as these technologies may be, NHTSA recognizes that risky driving behaviors and poor driver choices continue to amplify crash, injury, and fatality risks on our roadways. Those who commented on this issue generally supported moving forward and completing this as soon as possible. Forkenbrock, G.J., & Snyder, A.S. (2015, June), 237. https://www.regulations.gov, [12] Why or why not? 87. The lane keeping category included lane departure warning (LDW), lane keeping support (LKS),[24] As such, NHTSA believes that it is appropriate to harmonize with Euro NCAP on the maximum LVS test speed of 80 kph (49.7 mph), as this should better address the higher severity, high-speed crash problem and, in turn, further reduce fatalities and serious injuries. The proposed BSW tests represent pre-crash scenarios that correspond to a substantial portion of fatalities and injuries observed in real-world lane change crashes. Although travel speed was unknown or not reported for a high percentage of crashes in FARS and GES,[52] If yes, why, and for which test conditions? (Report No. Law Enforcement Programs Colorado Department of Transportation Start Printed Page 13457 A crashworthiness pedestrian protection testing program would measure how well passenger cars, trucks, and sport utility vehicles protect pedestrians in the event of a crash. Large-scale field test of forward collision alert and lane departure warning systems DOT HS 811 501), Washington, DC: National Highway Traffic Safety Administration. National Highway Traffic Safety Administration. 223. European New Car Assessment Programme (Euro NCAP) (2015, November), 1. Statistics of light-vehicle pre-crash scenarios based on 2011-2015 national crash data (30) For each lighting condition, the Agency is proposing 6 test speeds ( The program would further complement the safety achieved by pedestrian automatic emergency braking by measuring the safety performance of new vehicles to pedestrian impacts and encouraging safer vehicle designs for pedestrians. [169] This requirement was mandated by Section 10307 of the Safe, Accountable, Flexible, Efficient Transportation Equity Act; A Legacy for Users (SAFETEA-LU). For these reasons, the Agency tentatively concludes that it is more appropriate and better for the safety of consumers to set the forward plane of the blind zone at the rearmost part of the side view mirrors, as specified in its BSW test procedure. Estimation of potential safety benefits for pedestrian crash avoidance/mitigation systems This would further be supported by the Agency's proposal to require that five test trials be performed in instances where the SV is unable to meet the no contact performance requirement in the initial valid trial for that combination of test condition and speed. Alcohol-impaired driving continues to be a pervasive contributing factor to roadway fatalities, with over 10,000 deaths in the U.S. in 2019. What is the appropriate number of test trials to adopt for each BSI test scenario, and why? The results from these tests, as measured by the maximum excursions over the lane marking, were compared to the measured shoulder width of roads where fatal road departure crashes occurred. [226] In this instance, vehicles refers to the total number of vehicles in the 2021 fleet, and not the total number of vehicle models for that year. DOT HS 812 068), Washington, DC: National Highway Traffic Safety Administration. This type of seat belt misuse or non-use detection could be coupled with various types of seat belt interlock systems to encourage seat belt use.
