Abstract

A reduction in accidents, particularly secondary ones, is often cited as one of the primary benefits of a freeway traffic management system (FTMS) such as that implemented on a segment of Highway 401 in Toronto, Canada. The safety effect of this FTMS was estimated from the parameters of regression models calibrated for the preimplementation period (1989-1990) and the postimplementation period (1991-1992). Separate models were calibrated for express, collector, and conventional divided roadway sections and for rear-end, non-rear-end, and all injury accidents. For rear-end injury accidents, model parameters were estimated for day and night conditions. The aggregate results show a substantial decrease in the expected number of rear-end injury accidents on all three types of roadway following the implementation of the FTMS.
