TY - JOUR PY - 1999// TI - Traffic fatalities, Peltzman's model, and directed graphs JO - Accident analysis and prevention A1 - Roh, J. W. A1 - Bessler, D. A. A1 - Gilbert, R. F. SP - 55 EP - 61 VL - 31 IS - 1-2 N2 - We show how statistical methods based on directed graphs may be useful in modeling traffic fatalities by comparing models specified using directed graphs to a model originally developed by Peltzman. The comparison uses Peltzman's original data, as well as up-dated data (and coefficients) through 1993. Out-of-sample forecasts of traffic fatalities from Peltzman's model are compared with those from a model constructed using directed graphs over data for the more recent period. The directed graphs model outperforms Peltzman's model in root mean squared forecast error. LA - en SN - 0001-4575 UR - http://dx.doi.org/ ID - ref1 ER -
