Scope: This document specifies the terms and definitions, components, classification and naming, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage of portable road traffic lights. This document applies to portable road traffic lights used for temporarily controlling traffic flow at road intersections. Main technical content: Road traffic intersections often face special situations such as emergency power outages, signal light failures, and road construction. In such intersections, portable traffic lights are set up to temporarily replace the function of road traffic lights. These lights are highly convenient and adaptable, and can be widely and quickly applied to various intersections. Currently, due to the lack of unified standards, there are significant differences in functionality and inconsistent performance indicators. Problems include different shapes, substandard brightness, insufficient wind resistance, insufficient working time in continuous rainy days, poor mobility, and poor warning effectiveness. The market is also relatively chaotic, with poor product reliability, posing a potential threat to traffic safety. Therefore, it is necessary to jointly develop a group standard with major industry enterprises, associations, and traffic managers to standardize the main functions and performance requirements of products, and guide the healthy and sustainable development of the industry.
