Motorcycle Conspicuity – What Factors Have the Greatest Impact, 2012.

The Iowa Motorcycle Operator Manual states that when a motorcycle and another vehicle collide, more than half of these crashes are caused by drivers entering the rider’s right-of-way. Furthermore, in crashes with motorcyclists, drivers often say they never saw the motorcycle. Therefore, increasing motorcycle conspicuity could help address these issues, resulting in fewer crashes (and injuries and damage).

Motorcycle conspicuity: what factors have the greatest impact (tech transfer summary)

This research investigated the impact of motorcycle headlight configurations, rider colors, and age of the drivers (participants) on motorcycle conspicuity in simulated urban and rural environments.

Iowa Motorcycle Ride Meter, HR-1019, 1980

The Iowa Department of Transportation (Iowa DOT) through the Highway Division is responsible for the design, construction and maintenance of roadways that will provide a high level of serviceability to the motorist. First, the motorist expects to be able to get where he wants to go, but now he also demands a minimum level of comfort. In the construction of new roadways, the public is quick to express dissatisfaction with rough pavements. The Highway Division of the Iowa DOT (formerly Iowa State Highway Commission) has a specification which requires a "smooth-riding surface". For over 40 years, new portland cement concrete (pcc) pavement has been checked with a 10-foot rolling straightedge. The contractor is required to grind, saw or mill off all high spots that deviate more than 1/8" from the 10-foot straight line. Unfortunately, there are instances where a roadway that will meet the above criteria does not provide a "smooth-riding surface". The roadway may have monger undulations (swales) that result in an undesirable ride. The objective of this project was to develop a repeatable, reliable time stable, lightweight test unit to measure the riding quality of pcc pavement at normal highway speed the day after construction.

Enhancing Motorcycle Conspicuity Awareness in Iowa, 2010

Previous studies in the United States and internationally suggest that low motorcycle conspicuity, or the inability of the motorcyclist to be seen by other road users, is thought to be an important factor associated with risk of motorcycle crashes. However, there has been limited research on motorcycle conspicuity in the United States in the past two decades, while at the same time; there has been a renewed interest from states in increasing motorcycle conspicuity and motorist awareness. As such, this research revisits the motorcycle conspicuity problem by analysis of helmet-use and motorcycle crash data. First, this study reviews previous studies on motorcycle conspicuity with a focus on the effectiveness of proposed measures for enhancing motorcycle conspicuity. The major trends in motorcycle helmet use by time of day and road type for motorcyclists, as indicated from three roadside observational roadside surveys in Iowa, are also discussed. Then, using motorcycle crash data for Iowa from 2001 to 2008, this research compares single-and two-vehicle motorcycle crashes and examines the distribution of conspicuity related factors in light and dark conditions in two-vehicle crashes that could potentially relate to a collision between a motorcycle and another vehicle. The limitations of examining motorcycle conspicuity by analysis of crash data are also discussed. Finally, this report outlines recommendations based on the key findings of the study.
