After a blanket of dense fog wrapped Northern India, the National Highways Authority of India (NHAI) has come up with a series of engineering and safety awareness initiatives to prevent mishaps due to poor visibility.
Engineering measures include road sign repairs, markings
In a released statement, the NHAI said that it has taken mitigation measures through engineering, such as reinstalling missing or damaged road signs and road studs, rectifying faded or inadequate pavement markings, installing reflective markers and retro-reflective yellow stickers on road safety devices like metal beam crash barriers, and implementing safety measures on construction stretches.
NHAI uses radio and social media for fog-related safety alerts
These measures include use of Variable Message Signs (VMS) or electronic signages to display ‘Foggy Weather Alerts’ and speed limits, use of Public Address System warning commuters in foggy areas, use of electronic billboards, radio, and social media for public service announcements as well as installation of reflective tapes on vehicles to enhance visibility.
NHAI orders weekly night highway inspections
The NHAI also asked its field offices to undertake night-time highway inspection on weekly basis to assess visibility on National Highways and identify locations for installing additional provisions as required. Also, Highway Patrol vehicles will be stationed near dense foggy stretches, carrying blinking batons for guiding traffic. Also, use of reflective jackets by officials and workers during highway activities has been mandated.
