Abstract

Bicycles offer a promising transportation alternative to private motor vehicles, especially in areas with congestion, poor air quality, and high fuel prices. This study sought rational methods for evaluating the benefits of incorporating bicycle-friendly features into highway project designs. Data on recent bicyclist fatalities and other collisions involving bicyclists in Indiana were analyzed to determine factors that could help to explain the incidents and offer insights into countermeasures or remedies. Human error – on the part of the bicyclist or the motorist – was found to be the most common factor. Poor lighting and noncompliance with sidewalk ordinances also were frequent causes of bicycle crashes. A Bicycle Network Analysis Tool was developed to assess the level of service offered to bicyclists in a study area. The tool uses route length and measures of perceived safety to quantify the bicycle friendliness of a street network. The tool can be used to compare networks and assist in the selection of locations for bicycle facility improvements.
