Development of analysis procedure

Type of alternatives to be considered

Problems to be address

Analysis to be carried out Problem: 1- Analysis of subject Intersection with current and Future volume with existing signalized condition but with isolated intersection.

Problem: 2- Analysis of subject Intersection as a part of urban street and analyzing & comparing current and future conditions

Problem: 3- Analysis of urban street with different cases such as changing offset time, Changing phase sequence or increasing pretimed cycle length.

◦ Problem: 3a- Changing offset time: it should be adjusted in such a way that almost all the vehicle should arrive during green time.

◦ Problem: 3b- Analysis using Changing signal sequence◦ Problem: 3c- Analysis using Changing pretimed cycle duration from 52s to 80s

Problem: 4- Analysis of urban street with considering subject approach as actuated and all the intersection actuated.

◦ Problem: 4a- Analysis considering subject approach as actuated◦ Problem: 4b- Analysis considering all approaches as actuated
