Abstract

This research investigated whether a pedestrian fatality rate of a country responds differently to that of the vehicle occupant with respect to infrastructure, demography, and transportation factors. Road density, population density, Vehicle Travelled Kilometer (VKT) per vehicle and urban speed limit were chosen as infrastructure, demography, and transport factor respectively. This comparison is uniquely meaningful in that it was performed when the endogeneity of Vehicle Kilometer Travelled (VKT) per vehicle is reduced significantly. This research used macro panel data of the countries, members of the OECD International Transport Forum, from 1965 to 2014, and Two Stage Least Squares equations (2SLS) instrumenting VKT per vehicle with representative socioeconomic variables. The socio-economic variables included GDP, GDP per capita, employment rate, vehicle per capita, and price of unit fuel, which had been known to be correlated with VKT. The results showed clearly different patterns of the pedestrian fatality rate from those of the vehicle occupant with respect to the infrastructure, demography, and transportation factors. This result sheds light on that a policy customized for vehicle occupants might not be best appropriate for pedestrians considering a policy for a road user is usually an operational combination of those three factors, which are likely to respond to the two road users differently.
