System Operating

Historically, highway safety countermeasures have been developed in response to accidents. These countermeasures are based on the identification of contributing factors in the system operating environment that can be eliminated or changed so that the accidents caused by them will no longer occur. The road safety audit is a process whereby a team of experts attempts to identify features of the highway operating environment that could be potentially dangerous and then works to eliminate or change these features during the different phases of design before the system becomes operational. The Pennsylvania Department of Transportation (PennDOT) is interested in formulating a safety audit process for use on roads in the state. In cooperation with PennDOT, the Pennsylvania Transportation Institute conducted research on the application of a road safety audit process in two PennDOT districts.

Ohio faces the challenge, as do many other states, of how to utilize Highway Safety Improvement Program (HSIP) funding to improve safety on its low-volume roadways while meeting the data-driven safety funding requirements of the Fixing America’s Surface Transportation (FAST) Act. Low-volume roads present unique challenges because data is rarely available and other factors, such as roadway ownership, affect the implementation of safety countermeasures on this system. Beginning in 2014, the Ohio Department of Transportation (ODOT) created a township safety signage grant program designed to address the issues with utilizing HSIP funding on low-volume roadways. The grant program’s goal was to drive down the number of fatalities, serious injuries, and overall crashes occurring on Ohio’s low-volume roads. ODOT took into consideration overriding issues regarding low-volume roads in how it structured the grant program. ODOT also utilized the direction from its Strategic Highway Safety Plan in choosing a safety countermeasure which met the needs of its roadway departure and intersection crash trends. The program has been actively engaged in by Ohio townships and now has a large enough amount of post-safety countermeasure installation data available to quantify its initial success. This paper presents the successful results by highlighting the human capital and comprehensive societal benefit/cost analyses for the first 24 townships with 12 months of post-grant completion crash data.

Bayes Approach

A key step in highway safety management is to determine whether the frequency and/or severity of collisions have been reduced after implementing a specific improvement program. This research focused on evaluating the safety performance of 50 sites that have been improved under the Saskatchewan Ministry of Highways and Infrastructure’s (MHI) Safety Improvement Program (SIP). SIP projects were designed to reduce the frequency and severity of collisions on provincial highways in rural areas through the implementation of different safety countermeasures. The methodology adopted was an observational before-after study with the full Bayes approach. The results showed that SIP projects reduced total collisions by 14.8% and severe (fatal-plus-injury) collisions by 25.4%. The reduction of property-damage-only collisions was not found to be statistically significant. Crash modification factors (CMFs) for the two most frequent SIP treatments, i.e., right-turn lanes and delineation lighting at intersections, were estimated and compared to the results of the literature.
