Taxicab Driver Safety as a Public Health Issue • What is Public Health? • Multi-disciplinary • Comprehensive • Every level of society The advantage to recognizing taxicab driver safety as a public health issue is to use targeted, effective interventions in public health for increasing taxicab driver safety

Workplace Violence • Violent assaults and homicides are a leading cause of work-related deaths • 1997-2010, 8,666 workplace homicides occurred • 80% victims male • 80% shooting • 40% robbery-related • Retail, protective services, and transportation activities http://www.bls.gov/iif/oshwc/cfoi/work_hom.pdf

Why are Taxicab Drivers Disproportionately Affected? • NIOSH Alert identified following risk factors • Exchange of money with the public • Working alone or in small numbers • Working late night or early morning hours • Working in high crime areas • Guarding valuable property or possessions • Working in community settings Each ‘risk factor’ is normal daily activity for taxicab driver
Preventing Taxicab Driver Homicides • Safety Equipment • Security cameras • Partitions • GPS Dispatch/Alert • Administrative Policies/Procedures • Safety training • Cashless systems
Study Objectives • Primary Evaluate impact of cameras on homicides • Secondary Evaluate impact of partitions on homicides
Study Population • Nationwide • Major cities enrolled • Must have population >250,000 • Within MSAs, largest city selected • City that maintains taxicab licenses
Data Elements • Taxicab driver homicide count • Two data sources: news clippings and crime reports • Licensed taxicab count • Safety equipment status • City homicide rate • Collected per city and per year
Study Design/Analysis • Retrospective longitudinal time series analysis • 1996-2010 • Pre-post with comparison group • Poisson distribution with GEE • Dependent variable: taxicab driver fatality rates • Independent variables: safety equipment status

Taxicab Driver Homicides in Camera Cities Pre- and Post-Installation – Preliminary Data *indicates cities with an ordinance mandating cameras Numbers above columns indicate average annual rates of taxicab driver homicides per 10,000 licensed cabs
Modeling Intervention Effects on City-wide Taxicab Driver Homicide Rates – Preliminary Data *denotes statistical significance at p≤0.05

Taxicab Driver Homicides in Camera Cities Pre- and Post-Installation – Preliminary Data *indicates cities with an ordinance mandating cameras
Modeling Intervention Effects on City-wide Taxicab Driver Homicide Rates – Preliminary Data Bolding denotes statistical significance at p≤0.05
Preliminary Conclusions • Both data sources provide congruent findings • The installation of cameras seems to play a role in reducing taxicab driver homicides at a city level • There is no evidence to suggest partitions play a role in reducing taxicab driver homicides at a city level
Next Steps • Complete peer review and disseminate these findings to stakeholders – regulators, safety professionals, mayor’s offices, police departments • Interview taxicab drivers using different safety equipment to understand risk factors and protective factors at individual level • Evaluate the role of safety training
