Further,  under  Phase-III  of  the  projects,  the  NSV  shall  be  deployed across 23 States of the country covering a distance of approx. 21000 Km. (b)  &  (c)  Government  has  finalized  criteria  for  identification  of  road accident  spots  as  black  spot  depending  on  number  of  accidents  in three  consecutive  calendar  years  involving  fatalities  and  grievous injuries, based on the road accident data provided by all the State/UT Governments. Government has issued guidelines for immediate short-term rectification  measures  on  black  spots  like  road  markings,  signages, crash  barriers,  road  studs,  delineators,  closure  of  median  openings, traffic calming measures, etc. Long term rectification works include improvement of road geometric, junction improvements, spot widening of carriageway, construction of underpasses/overpasses, etc. which involve pre-construction activities such  as  land  acquisition,  forest  clearance  &  utility  shifting,  takes significant time. As  of  now,  short-term  rectification  has  been  completed  on  12,490 black  spots.  Long-term  rectification  measures,  as  recommended  by road safety audit reports, are implemented only at locations deemed necessary. Accordingly, long-term measures have been completed at 5,942 black spots, while 3,709 black spots have been assessed as not requiring such long-term interventions. (d)    A  total  of  112  black  spots  are  identified  on  NHs  in  Palakkad district,  out  of  which  on  37  black  spots,  short  term  measures  are completed and on 75 black spots, short term measures are ongoing.
