“…This is mainly due to the reduction of conflict points while prohibiting the left turn maneuver. This result is consistent with the studies done by Liu, Lu, and Chen (2007), Lu, Dissanayake, and Xu (2001), Lu, Dissanayake, and Castillo (2001), and Pernia (2004, 2005), who found that there is a reduction in total crashes and fatality for right turns followed by Uturns, as an alternative to direct left turn maneuvers from driveways. However, the probit estimate is not statistically significant at the 90% confidence.…”

“…Another study conducted by Liu et al (2008) investigated the impacts of the separation distances between driveway exits and downstream U-turn locations on the safety performance of rightturns followed by U-turns. Liu et al studied 140 select street segments in the State of Florida, all of which were urban or suburban arterial segments with non-traversable medians and directional median openings.…”

Sponsoring Agency Code Supplementary Notes AbstractThis Report reviews an Oregon research effort to develop an Oregon Access Management Best Practices Manual. In particular, this research effort develops a resource to help transportation professionals quantify safety and operational effects of various access management strategies, provide measurable criteria to evaluate these access management techniques, and identify data collection practices necessary to successfully perform these assessments. It is the expectation that this manual can be used by engineers, decision makers, and educators to help the transportation community better understand the appropriate application of access management strategies and how to quantify benefits of the various access management options.This report includes a literature review of safety and operational benefits for a variety of access management configurations. Included in this benefits summary is information about perceived and measured economic impacts of access management even though they are not explicitly included in the companion manual. In addition, this report summarizes example data for access management through the use of case studies, and includes (in the appendix) a standalone proposed access management best practices manual. The case studies were used to test practicality of acquiring various data elements and are not directly reflected in the manual.17.

“…Similarly, about 3000 road users are killed each year on Canadian roads, resulting in an estimated social cost of about $25 billion (Transport Canada, 2004). Among the different road segments, intersections are considered to be one of the most hazardous locations (Abdel-Aty and Keller, 2005;Wang and Abdel-Aty, 2008;Liu et al, 2008;Tay and Rifaat, 2007;Yan et al, 2005Yan et al, , 2007. For example, in the state of Florida, 43.1% of fatalities and serious injuries occurred at or were influenced by intersections (Wang and Abdel-Aty, 2008).…”
