Saving lives through accident research!

Kolkata city accident research initiative

• Jointly initiated by Kolkata Traffic Police, CII, ITC and JPRI.
• On-site crash investigation of fatal accidents with the support of Kolkata

traffic police since November 2014.

Results of

• ne year study

9 September, 2016 CII Safety Symposium & Exposition 2016 3

• 316 Fatal accidents
• Fatal accidents are

widely spread around Kolkata city.

Note: 316 fatal accidents notified to JPRI from Nov’ 2014 to Nov’ 2015.

Infrastructure factors leading to fatal pedestrian crossing accidents

• 72% of fatal pedestrian accident occurs when pedestrians are trying to cross the road.
• 76% of fatal pedestrian crossing accident occurs at or near junctions.

Infrastructure factors leading to fatal pedestrian walking alongside accidents

• 28% of fatal pedestrian accident occurs when pedestrians are walking

alongside the road.

Example: Vehicle factor (Knock down)

9 September, 2016 CII Safety Symposium & Exposition 2016 19

Knock down: Pedestrians when impacted by another vehicle, lose balance due to shift in CG and fall down on the ground, resulting in injuries to the pedestrian .

Vehicle factors (Knock down accidents)

• Two of every three (66%) pedestrian fatalities is a knock down.

Example: Vehicle factor (Run over)

9 September, 2016 CII Safety Symposium & Exposition 2016 24

Run over: In an event of impact, pedestrians will be knock down to the ground and are run

• ver by the wheels of the accident vehicle (usually a bus or a truck). This usually occurs due to

a large ground clearance between the vehicle and the ground.

Vehicle factors (Run over accidents)

• One of every three pedestrian fatalities is a run over

Smart solutions (Run over) Vehicles with low ground clearance

9 September, 2016 CII Safety Symposium & Exposition 2016 26

• No run over accidents seen so far in Kolkata

city with buses of low ground clearance .

• Introducing more buses of this type will

subsequently mitigate pedestrian run over accidents in Kolkata city.

Conclusions

• One pedestrian dies every second day in Kolkata city roads.
• For a safer pedestrian journey in Kolkata city roads:

1. Pedestrian infrastructure problems need to be addressed.

• Proper pedestrian traffic lights.
• Reduce the pedestrian crossing distance by refuge islands.
• Intersections with proper pedestrian crossings.
• Proper pedestrian pavements without encroachments.

2. Pedestrian vehicle problems need to be addressed.

• Autonomous Emergency Braking Systems (AEBS).
• Blind spot assist system.
• Buses and trucks with low ground clearance.
• Run over prevention device.
