This project evaluated bicycle-lane additions when reducing lane and shoulder width as a safety-improvement strategy (also known as a safety intervention). Crash modification factors (CMFs) and benefit–cost (B/C) ratios were estimated for total, fatal and injury, and property-damage-only (PDO) crashes. Researchers studied facilities that included u

The early settlers who came to America found a land of dense wilderness, interlaced with creeks, rivers, and streams. Within this wilderness was an extensive network of trails, many of which were created by the migration of the buffalo and used by the Native American Indians as hunting and trading routes. These primitive trails were at first crooke

Traditionally, travel forecasting models have been used to provide single point predictions. That is, a single future scenario is developed, and the model is applied to that scenario. This approach, however, ignores the deep uncertainty that exists in future land use, demographic, and transportation systems inputs, not to mention the uncertainty th
