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

Fatalities around Sample Stops
Monday, 17 September 2018 TRIPP, IIT Delhi 46
• 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

2 Hospital data Crash details are not recorded, depends on
the specialty of the hospital
3 Special
Agencies(conc
essionaires)
BOT operators or toll operators maintain
record of crashes causing damage to the
road furniture along with other crashes
4 Insurance Depends on what injuries and damage to
the vehicles are compensated
5 Research teams Misses out fatal pedestrian and bicycle
crashes where victims are removed quickly
Table 5: Data sources and possible biases
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.
