Abstract

This paper reports on a crash prediction model that was used to estimate the change in truck-related crashes on parallel arterials caused by the diversion of truck trips from prospective truck-only toll (TOT) lanes in the Atlanta freeway network. A negative binomial regression was used to model truck crash prediction on arterial roads. Three variables, vehicle-kilometres travelled, truck percent-kilometres per lane, and the volume-to-capacity ratio, are shown to have significant influence on truck-related crashes. Two toll policies of mandatory and voluntary use of TOT lanes were examined to determine their effects on truck-related crashes on parallel arterials. It was estimated that an average of 8% and 6% reduction in truck crash frequency, respectively, would occur.
