ISKON Rotary Intersection on S.G Highway in Ahmedabad as Signalized Intersection - A Case Study

Alpana Jha

ISKON Rotary Intersection on S.G highway in Ahmedabad is a four-legged rotary intersection and has potentially failed as flow is much higher than the capacity of rotary. Rotary is oversaturated and the LOS is F. Intersection performance is evaluated if it is converted to signalized intersection. Traffic flow coming from sharkhej, Gandhinagar, Bopal and Satellite road was recorded for the intersection. Traffic consists of car, auto-rickshaw, bus, two wheelers and bicycle. Data for Lane Group, Approach volume, Intersection volume at ISKON intersection is collected. ISKON intersection volume is 6107 veh/hr. Maximum approach volumes is on north approach i.e from Theltej side which is 1770 veh/hr. It is 29 % of total intersection volume. Minimum approach volume is on west side i.e from Bopal side which is 1419 veh / hr. It is 23 % of total intersection volume. A four phase signal system is selected for the intersection. Amber time, Pedestrian crossing time Optimal cycle length and Delay is Determined. Even if ISKON rotary intersection is converted to signalized intersection, LOS is E and D which is not very much desired. So conversion of ISKON rotary intersection to signalized intersection is not justified.

Keywords: Rotary Intersection, signalized intersection, Level of service, Optimum cycle length, Critical flow ratios
