noted that although devices used in autonomous
goods delivery fall outside J3194's scope, SAE is
exploring how the organization might in the future
play a role in their development and use.
J3194 also does not prescribe safe or appropriate
classifications of vehicles, nor does it suggest where in
the transportation system the vehicle should operate.
A more recently approved standard under the
micromobility committee's domain is J3230/01202102
Kinematic Performance Metrics for Powered
Standing Scooters. Among other things, it spells out
test procedures to measure a scooter's top speed,
acceleration and deceleration. Roadway conditions
and operator anthropometry are among the factors
considered in test scenarios under the standard.
Two other standards are under development,
including SAE J3274 Minimum Sound Requirements
for Powered Standing and Seated Scooters. Many
powered micromobility vehicles do not emit sound
signatures. The quiet nature of these vehicles has
raised concerns for safety of pedestrians and persons
with disabilities, particularly low-vision and blind
individuals. J3274 establishes performance
requirements for pedestrian alert sounds for powered
standing and seated scooters as defined in SAE J3194.
Specifically, it establishes a set range of sound
characteristics for sound frequency and sound
pressure levels for select vehicle operation scenarios.
Testing procedures are prescribed for each scenario.
The other work in progress, SAE J3272 Powered
Micromobility Vehicle Identification, is intended to
provide a means of identification of Powered
Micromobility Vehicle classes and characteristics
through use of an alpha-numeric identifier. This
document will apply primarily to the device classes
identified in SAE J3194. n
