CURRENT
MA1370A
This standard specifies the characteristics of the MJ profile metric series of screw threads, altered from ISO 68 M Profile, to include a mandatory controlled radius of 0.18042P to 0.15011P at the root of the external thread and with the minor diameter of both external and internal threads increased to provide a basic thread height of 0.5625H in order to accommodate the external thread maximum root radius.

Initial Research Summation Overview: Vehicle-VRU Safety Landscape

2023-12-18
CURRENT
VRUSC-001-2023
This white paper is an examination of the increasing rate of injuries and deaths worldwide of a class of road users, often referred to as “vulnerable road users” (VRUs), with a focus on pedestrians, cyclists, scooterists, highway road workers, safety, and emergency personnel. The potential to leverage pragmatic, evidence-based technology countermeasures to reduce these collisions, and the severity of those that do occur, is also examined.
