The concept of the level of service of safety (LOSS) was developed at the Colorado Department of Transportation in 2000. LOSS reflects how a roadway segment or an intersection is performing in reference to the expected frequency and severity of crash

Speed–flow relationships for a typical basic freeway segment are understood well at present and are documented by the successive editions of the Highway Capacity Manual. Recent freeway studies showed that speed on freeways was not affected by low t

The decision to add lanes to a freeway is motivated by the need to relieve congestion. Practicing engineers and planners generally believe that the decreased congestion that results from adding lanes is associated with some degree of improved safety,

Decisions to run traffic on freeway shoulders during peak periods are motivated by the need to relieve congestion. Practicing traffic engineers generally believe that the decreased congestion resulting from running traffic on hard shoulders (i.e., ha

Constructive discussion of the appropriate choice for the functional form of safety performance functions (SPFs) is generally absent from research literature on road safety. Among researchers who develop SPFs, there appears to be a consensus that the

This paper first explores the relationship between safety and congestion and then examines the relationship between safety and the number of lanes on urban freeways. The relationship between safety and congestion on urban freeways was explored with t

Safety-conscious planning is a relatively new concept. It was developed in response to safety-related provisions of the Transportation Equity Act for the 21st Century (TEA-21) of 1998, which required explicit consideration of safety in the transporta

The starting point for a program of local safety improvements is the preparation of a list of sites with promise at which to conduct a detailed engineering study, by which cost-effective projects can be identified. Inclusion on the list depends on th

The Transportation Equity Act for the 21st Century of 1998 required explicit consideration of safety in the transportation planning process. Although this government mandate is well intentioned, little is known about how to accomplish it. Despite 60

While some initial and significant progress has been made in the development of a highway safety manual, much remains to be done in the areas of conceptual development and the diagnostics of safety problems. The concept of level of service of safety
