Title: Safety Benefits of Converting HOV Lanes to HOT Lanes: Case Study of the I-394 MnPASS
Abstract: In 2005, high-occupancy-vehicle (HOV) lanes on I-394 in Minnesota were converted to high occupancy toll (HOT) lanes. In order to evaluate the effect of HOV-to-HOT lane conversion on highway safety, this study uses an empirical Bayes method to examine the accident rate on the I-394 HOT lane before and after the conversion. The findings show that the number of crashes was reduced by 5.3% following the conversion, from an average total of 496 crashes before 2005 to an average total of 392.5 after 2005. The economic benefit of these reduced crashes for 2006 and 2008 was approximately $5 million. Limitations of this study and directions for future research are suggested.
