Feedback before the experiment
Shopkeepers, Pedestrians and Motorists
What we have needs to
change
What we have is alright

5. PUBLIC CONNECT | TCL – Vijay Crossing
High number of pedestrians

Issues
Parking at intersection and footpath
Conflict between traffic, pedestrians and parked vehicles
No safe crossing path for pedestrians
High speed of turning vehicles
High incidence of wrong turning vehicles

No lane discipline
Wide open left turns
Unguided road space
8 m
Too wide carriage way
Delay in junction clearance
8 m

No sight distance for pedestrians
Left turn with high speed
Unsafe pedestrians

13. PUBLIC CONNECT | TCL – Vijay Crossing
Unsafe pedestrians
Island covered by greenery
Mix of traffic
Unrestrictive u turn
No refuge while crossing at
junction – median too far – too
narrow

18. Improving SAFETY while crossing the road
Safe left turns

19. Improving SAFETY while crossing the road
Speed reduced by 60%

20. Improving SAFETY while crossing the road
A space to wait while crossingImproved and constrained turning – notice the police standing in the refuge

21. Junction Re-design
Existing Situation – No clear space for cyclists and pedestrians which is blocked by parked
vehicles

22. Junction Re-design
New Situation – Space created for cyclists and pedestrians by aligning parking away from
edge.

Day
Much talking to people helps

35. Day 3
Improving SAFETY while crossing the road
Day
Parking getting organized again

36. Day 4
Talking talking and more talking to people
To get them to understand new parking space
Improving SAFETY while crossing the road

37. Day 5
Much discipline observed
Improving SAFETY while crossing the road

38. Day 5
Improving SAFETY while crossing the road
Observed managed parking

39. Issues on street (Shopkeepers)
IMPACT

40. Do you feel street safe? (pedestrians)
IMPACT

41. THE IMPACT
Geometric Design of Junction
Pedestrian safety at the junction. High Increase
Safety for cyclists at the junction. Little Increase
High 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
