Hi Chritra,
 
how does your network look like (especially around the E3 detectors) and 
what numbers are we talking about (40% of which vehicle volume)? As I don't 
know your scenario I see these options:
    * the vehicle volume is very low even at 80% of the reference volume
      or...
    * the volume is very high such that not much more than 40% of the
      reference vehicle volume can be inserted in the network( due to the
      number of insertion lanes and the configured follower distance /
      car-following model settings)
    * all cars use the same car-following model settings (=keep the same
      distance) and have the right-of-way along the E3 detector lanes (no
      need to brake)
Did you actually watch the vehicles in sumo-gui?
 
Best regards
Mirko

Hello,
 
While analysing the MeanTimeLoss values from E3 detectors in SUMO for 
different traffic conditions (varying volume), I have obtained results 
where even though the input volume is increasing from 40% to 80%, the 
average vehicular delay is not varying significantly as that of volume. The 
average delay is concentrated over a very short range ( 43 s/veh to 45 
s/veh). 
 
Is there any possible reason for this unexpected results from SUMO?
 
Thanking you in advance.
