PRIMARY LEVEL DATA

•Expected to accomplish the following functions:

1. To give perspective view of the RTC situation in terms of i. who is involved (the type of road user) ii. where (Urban or rural area, road layout),iii. when (day or night) and under what circumstances.

2. To enable trends to be examined,3. Provide a basis for comparison against which road safety

professionals may match their performance, either within or between state or national administrations.

Establishing priorities for action.

Need for the revision/modification

• Under reporting of victims specially of pedestrians, cyclists and motorcyclists etc.(Mohan etal.2005, Bhalla et al. 2016)

• Non usage of standardised recording formats at the police station level

• Doubts over some reported data due to inadequate information at the police station

• Inadequate details of impacting vehicle.

Road Accident Recording & Reporting Form 4

Comprehensive format covers

• Format for recording road accident data by the Police at accident site covers the following :.

i. A. Accident identification details

ii. B. Road related details

iii. C. Vehicles involved in accident

iv. D. Drivers details &

v. E. Persons other than drivers involved in accident.

Road Accident Recording & Reporting Form 6

New details

Simplified definitions

GPS details for location

Use of safety devises

Identification of victim & impacting vehicle

Summary of 5 regional workshops(March -June2017)

• Standardised format is not used by police stations, shortage of manpower

• Details other than FIR format should be filled by other people, police under home ministry records as per the requirements of FIR/CCTNS

• TRW must coordinate with CCTNS to improve recording &reporting.

• Some training is required at police station level for data recording

• Recording format should be filled up at the time of closing the case file.

• 30% of the details can be filled at the time of filing the FIR.

• MoRTH should provide a software combining recording and reporting format.

Shortcomings

Shortcomings of police data

•National level tables(NCRB) for victims are based on “road user causing the accident, therefore pedestrians and bicyclists numbers are incorrect (lower than actual numbers)

• Location is available in the case file, not marked on the map for analysis and remedial measures

• Analyzed Pedestrian Fatal Accidents, 2006-09

Top eight roads of Delhi in decreasing order of pedestrian fatal accidents, 2006

• Analyzed Rate of pedestrian fatal accidents per year over the

arterial roads

Contd.

• Pedestrian fatalities by buses in four years = 353

• Minor Roads = 35%

• Arterial Roads = 22%

• Sub-Arterial Roads = 15%

• Collector Roads = 11%

Rest 17% were not captured in 20m buffer on both sides of centerline of roads

Analysis of fatalities at arterial roads done by GIS shows that –

• 14% of Arterial roads’ accidents were at arterial to arterial road intersections

• 10% of Arterial roads’ accidents were at arterial to sub-arterial road intersections

• Rest 76% at mid-blocks of arterial roads

Buffer radii chosen at arterial intersections was 150m and at arterial-sub arterial intersections was 15m

• 22% were on arterial roads

• 15% were on sub-arterial roads

• 11% were on collector roads

• 35% were on minor roads

• 17% was not captured in the given buffer distance

Striking Vehicle – Unknown

• 28% were on arterial roads

• 13% were on sub-arterial roads

• 4% were on collector roads

• 37% were on minor roads

• 17% was not captured in the given buffer distance


Kernel Density Map


Fatalities around Sample Stops


• Moran’s Index = 0.119

• Expected Index = –0.003

• z-Score = 0.587

• p-value = 0.557

• Pattern does not appear to be significantly different than random

Conclusions

• Fatalities around bus stops do not display any significant clustering

• Proportions of striking vehicles and victims around bus stops is not significantly different from all of Delhi

• Hence, bus stops are not particularly more unsafe than other areas in the city

• Lack of correlation between safety score in audit and high-crash locations of bus stops indicates revision of PTA audit toolkit required


Future Directions

•FIRs should be freely available (Haryana and Punjab FIRs on web)

•Specialist groups in research and academic institutes for secondary level analysis( evaluation of design standards, construction guidelines,etc)

•Specialists groups in Academic institutes in collaboration with automotive industry for vehicle standards

Recommendations

Short term

• The recording format should be filled by the investigating officer. A copy of the completed form can be attached with the case file and also sent to DCRB.

• An excel data base can be created for generating the required reports at the police station.

REcommendations

Long Term

• Data of fatal crashes may be maintained separately with more complete information with the help of RTO, PWD, NHAI.

• Fatal crash data quality should be checked at a regional or state level and saved in a central data base. This may require TRW, MoRTH appointed state level officers.

• IITS can assist TRW-MoRTH in coordinating the checking, and cleaning of the fatal crash data and periodic training of police officers for improving the recording and reporting of crash data.
