     This case  shows  how  to apply PLANT to introduce  the traffic
     induced turbulent  diffusion  for  the  problem  of   vehicular
     exhaust dispersion in the street canyon.

     It is  assumed  that  by  the  order  of magnitude the traffic
     caused turbulent  kinematic  viscosity  is  the  length  scale
     squared  times  relative  velocity  divided  by car size.  The
     length scale is choosed as smallest of Prandtl  mixing  length
     and  constant  times  the car size as set in Group 9 ( see the
     line marked PRPT1 ).

     The layer under influence is located in a few slabs  over  the
     ground of street canyon.
