HajiHaji AliAli±±Cadbury LinkCadbury LinkA Capacity IssueA Capacity Issue

y Peak hour Straight and lef t moving traff ic demands denoted as v(SL) are clubbed together because of similar travel constraints

y Peak hour Right moving traff ic demand-v(R)- forms a complementary demandwhen there are a maximum of four legs to an intersection

y Together v(SL) and v(R) form Mutually Exclusive and Collectively Exhaustive (MECE) demand for link capacity

y Capacity per link is taken as 1800 vehicles per lane per hour (universal convention for high congestion links) eg: 3 lanes available for SL traff ic is

treated as a capacity of 5400 vehicles denoted as c(SL)y v/c ratio or Vehicle/ Capacity ratio is the ratio of demand f rom a particular

direction to available capacity for that directiony For a link to be able to provide a congestion f ree conduit under ideal

conditions, the sum of v/c ratios for all the MECE demands should be less than1 ie. v(SL)/c(SL) + v(R)/c(R) < 1

y If such condition is not satisf ied, then the congestion is inevitable during peakhour demands and the only solution is to try to ease congestion by makingmovement as seamless as possible

RecommendationsRecommendations -- SummarySummary

y The Haji Ali junction & Cadbury junction f aces

capacity constraint that will worsen with increasing demand

y Eff ect of optimized signal timings during the peak hours is minimized due to this capacity

constraint

y Creating seamless connections betweendiff erent traff ic directions is the best way toreduce congestion during peak hour traff ic




y Extension of Race Course road and constraining f ree

lef t towards Cadbury coming f rom Tardeo does not help in easing traff ic

y Use of 2 car decks as per proposal being evaluated by BMC can help in easing traff ic but does not completely eliminate conf licts in traff ic demand

directions.

y This will lead to signif icant congestion problems as the traff ic demands increase - congestion always takes a small time to build but a very long time toclear




y The solution proposed by Medulla-Sof t (3car decks) can be highly eff ective inmitigating the eff ect of congestion and

can also handle increased traff ic volumes caused by addition of vehicles to the city traff ic or by other changes such as extension of sea Link near Haji Ali




y For an even more sustainable solution,network level analysis and sensitivity analysis needs to be connected wherein

rerouting network f low can result insignif icant enhancement of traff ic throughput and reduction of congestion.
