Currently, we are working on the safety assessment at signalized intersections under Indian traffic condition which is highly heterogeneous in nature. At the selected study sites, some amount of vehicles are violating the red lights i) which stand in the front positions of the queue and start moving/entering the intersection before the signal turns green (we are referring to them as red light violations at the end of red phase) ii) after yellow time i.e. at the beginning of red phase a few vehicles are entering the intersection. We have prepared the network in VISSIM, but we are unable to generate the situations of red light violation in VISSIM. Any suggestions/advice regarding the above-mentioned problem will be greatly appreciated. Thanks in advance.
Why not, simulate with slightly reduced red time and/or play with the reaction time at stop.
For instance, Say the red light violation occurs at 5 s before the end of red. Then consider reducing the red by 5 s and add dummy phase (for 5 s) that allows the permissive movement of the vehicles from the approach of interest.
Thanks Professor. Let me try that tomorrow and revert you back with the updates!
