General procedures3 Terms and definitionsThe following terms and definitions apply to this document. 3.1 Tunnel environmental indicators tunnelenvironmentindicators In this section, environmental indicators refer to the environmental parameters used for expressway tunnel traffic operations, including. carbon monoxide concentration, visibility (smoke Fog concentration), brightness, wind speed and direction. 3.2 Carbon monoxide concentration of carbon monoxide Carbon monoxide concentration in the air per unit volume of CO, in units of 10-6. 3.3 Visibility attenuation coefficient visibilitydimmingcoefficient VI mainly reflects the concentration of smoke or dust in the environment, in units of 1/m (1/m). 3.4 Luminance The luminous intensity of a certain point of the surface of the light source in a given direction and the orthographic projection surface of the same on a plane perpendicular to the direction Plot ratio, in candela per square meter (cd/m2). Usually in the tunnel and tunnel each installed a light intensity sensor. 3.5 Windspeedanddirection TW The horizontal distance traveled by the air per unit of time in meters per second (m/s). The measured value is expressed as a positive/negative wind direction. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 34428.5-2017_English be delivered?Answer: Upon your order, we will start to translate GB/T 34428.5-2017_English as soon as possible, and keep you informed of the progress.
