Feedback before the experimentShopkeepers, Pedestrians and Motorists

What we have needs to change

What we have is alright


High number of pedestrians


Issues

Parking at intersection and footpathConflict between traffic, pedestrians and parked vehiclesNo safe crossing path for pedestriansHigh speed of turning vehiclesHigh incidence of wrong turning vehicles

No lane discipline

Wide open left turnsUnguided road space

8 m

Too wide carriage way

Delay in junction clearance

8 m


No sight distance for pedestriansLeft turn with high speed

Unsafe pedestrians


Unsafe pedestriansIsland covered by greenery

Mix of trafficUnrestrictive u turn

No refuge while crossing at junction – median too far – too narrow





Improving SAFETY while crossing the road

Safe left turns


Speed reduced by 60%


A space to wait while crossingImproved and constrained turning – notice the police standing in the refuge

Junction Re-design

Existing Situation – No clear space for cyclists and pedestrians which is blocked by parked vehicles

Junction Re-design

New Situation – Space created for cyclists and pedestrians by aligning parking away from edge.

DAY 0Implementation


Day 1Slow left turns


Day 1Slow U turns


Day 1Parking getting organized


Day 2


Day 1More walking space,But parking persists

Day 2


Day 1Refuge helps

Day 3


Day Parking back to its original position

Day 3


Day Much talking to people helps

Day 3


Day Parking getting organized again

Day 4Talking talking and more talking to peopleTo get them to understand new parking space


Day 5Much discipline observed


Day 5


Observed managed parking

Issues on street (Shopkeepers)

IMPACT

Do you feel street safe? (pedestrians)

IMPACT

THE IMPACT

Geometric Design of Junction

Pedestrian safety at the junction. High IncreaseSafety for cyclists at the junction. Little IncreaseHigh turning speeds. Reduced by 60%High incidence of wrong lane driving (opposite currents). Reduced by 90%Large wait time at junctions. Decrease by 35%Managing traffic. Easy
