Involvement refers to the vehicle being identified as either causing the accident or consisting of vehicle occupants who were victims of the accidents.
Along the 45-degree line, the share of PKT = the share in fatalities/serious injuries. PKT is used to represent motorized modes by their share in volume of traffic. If a mode lies above the line, it shows a difference in the share in PKT from the share in total fatalities, and thus appears to be more dangerous than other motorized modes of transport. Figures in parentheses indicate daily fatality/serious injury rates.

All Tables, Charts: Mumbai Traffic Police, Traffic TrainingInstitute, BycullaTwo main reports used:a) Yearly Accident Review (2008-2012)b) Annual report generated by Mumbai Traffic Police(19-page, 7-page)[2008-2012]Passenger Kilometres Travelled [PKT] (CTS, MMRDA)for representing traffic volumes in MumbaiMethodology: Data Sources
Trends in fatalities and serious injuries (2008-12)
Data shows a reduction of 13% in total fatalities in Mumbaifor 2012 in comparison with 2011Serious injuries, however, have increased by 2% in thesame period.Past three years show a general decline in fatalitiesTrends in fatalities and serious injuries for 2011-2012

Passenger-Kilometres Travelled indicates the total distancecovered by each mode of transport with reference to numberof passengers (public transport carries large number ofpeople over long distances, hence will have high PKT).Greater representativeness in safety assessment of variousmodesSince PKT data for 2012 was not available, 2008 data isused for analysis (see following figures)Rationale behind using Passenger KilometresTravelled (PKT) data

Auto-rickshaws shown to contribute less towardsfatalities, but have greater share in serious injuries.Cars and motorcycles appear to be the least safe modes (onthe basis of accident data) of passenger transport.Rapid growth of private motor vehicles appears to be acausal factorFatalities and Serious Injuries Findings
