Pedestrian and bicycle accidents in the United States result in approximately 80,000 and 50,000 injuries each year, respectively. Though pedestrians and bicycles move differently, they share important characteristics as both have little protection during a roadway collision with a motor vehicle. Therefore, to minimize the risk of injury, cyclists should wear helmets and both should obey traffic laws. The responsibility to avoid collisions also rests with motor vehicle drivers, who must obey traffic signals and yield to pedestrians and cyclists when appropriate. In many accidents, the visibility of pedestrians and cyclists to drivers, and vice-versa, is of central concern.
We have experience in many aspects of pedestrian and bicycle accidents including:
Through scientific analysis, we can help you answer pertinent questions such as:
Bus Striking Boy in Crosswalk:
A young boy was crossing a street with his aunt in New York City. Before he reached the other side, he was struck by a city transit bus whose driver claimed to have had a green light. We were able to show, based on the timing of the lights and measurements of the roadway, that the bus driver had more than enough time to perceive and react to the boy in the crosswalk and could have safely stopped the bus before impact, and further that the boy was not walking unusually slowly.
Child Darting onto Roadway:
A car driver struck a boy running across a wide, busy roadway. Based on one accident investigation, it was not clear why the boy and driver did not see one another before the impact. We hypothesized that there must have been a nearby traveling vehicle between them obscuring the line of sight. A deposition witness later testified that such a car was present. This cleared the driver of negligence and resulted in a minimal settlement.

Forensic Engineering Experts: Occupant Injuries
In many vehicle accident investigations, it is necessary to know not only the speeds and motions of the vehicles involved, but the causes of injuries suffered by their occupants as well. Such investigations seek to answer questions regarding occupant ejection, effects of seatbelt use, airbag deployment and body-interior impacts.

Forensic Engineering Experts: Biomechanics
Biomechanics is the application of mechanics to the interaction of biological systems with their external environment. When investigating an accident, biomechanical analysis can be used to reconstruct a victim’s motion and relate it to his injuries.

Children Will Fall At Playgrounds. What Shall We Do To Protect Them? - Part I
By: Jeffery Warren and Aron Olson
In 2011, a 5-year old boy was severely injured at a public playground when he fell through a second floor opening around a fireman's pole in a playhouse. He fell more than seven feet and struck a bare concrete floor. We are thankful that he eventually recovered from his injuries. The person who designed and built the playground was accused of negligence. A lawsuit ensued, and eventually settled in favor of the boy.
