Abstract
On July 1, 2013, the Ohio's legislature raised speed limits on rural freeways from 65 to 70 mi/h for all vehicles. This study investigated the impact of raising speed limits on crash severity specifically with interest on heavy vehicles on rural freeways in Ohio. Statewide crash data from January 1, 2010, to December 31, 2018, were used in this study. Because of the model requirement for stationarity on a response series, this study utilized the autoregressive integrated moving average (ARIMA) time series intervention analysis method using monthly crash data. Results of the study show that raising speed limits on selected segments of Ohio rural freeways has an impact on the frequency and severity of crashes associated with large trucks and buses. Moreover, the study found that bad winter weather conditions had a significant impact on the frequency and severity of crashes associated with large trucks and buses as they happen to be higher during winter seasons as compared to other times of the year.
