Abstract:

The goal of this project was to quantify the effects of managed lanes separation type on the safety performance of freeway facilities with managed lanes. The primary objective of the project was to develop quantitative measures that will be useful in comparing separation treatment alternatives for managed lanes. Following a comprehensive review of the state-of-practice, performance measures, and studies conducted on managed lanes by different agencies in the U.S., data were collected and processed for study sites in Florida, Texas, and Georgia. Data collected consisted of roadway characteristics, traffic volumes, roadway geometric cross-section of the managed lanes facilities, separation types (i.e., pylons and concrete barriers), operation strategies (i.e., nonreversible managed lanes, reversible managed lanes, etc.), and crashes for the years 2015–2019.
