NTSB ACCIDENT REPORT: Deadly Crashes at Unsignalized Intersections

From 2010 to 2015, more than 45,000 people were killed in intersection crashes in the United States. More than 66 percent of these crashes occurred at unsignalized intersections (where no highway traffic signals control right-of-way), accounting for over 15 percent of all fatal crashes on US roadways.

Intersections allow for potentially deadly impact angles and high collision speeds, which combine to limit survivability in the event of a crash. The National Transportation Safety Board (NTSB) has investigated several accidents that involved unsignalized intersections.

  • On July 2, 2016, near St. Marks, Florida, bus transporting 33 farm workers failed to stop at an intersection and proceeded into the path of a truck-tractor semitrailer combination vehicle. When the truck struck the bus, its right side-mounted diesel fuel tank was breached, initiating a fire. The truck driver and three bus passengers died; the bus driver and 30 passengers were injured.
  • On March 30, 2015, near Moore Haven, Florida, a 15-passenger van failed to stop at an intersection, traveled through the cross highway, and vaulted across a canal into the far-side bank. Eight people were killed, and eight were injured.
  • On February 16, 2012, near Chesterfield, New Jersey, school bus transporting 25 students entered an intersection without yielding to a truck traveling on the cross highway. The truck hit the school bus, which then struck a traffic beacon support pole. One bus passenger was killed, and 15 bus passengers were injured.

What can local traffic engineering authorities do to prevent and mitigate crashes at unsignalized intersections?

Traffic authorities can adopt “safe system” design principles—which means acknowledging human limitations and vulnerabilities and accounting for them as best as possible in road design. Although individuals have a responsibility to act with care and within traffic laws, those who design, build, and manage roads must also take proactive steps to improve safety by managing or eliminating risks where possible.

Another way to address this problem is to implement a systemic approach to safety, which targets common risk factors in crashes throughout the roadway network rather than focusing on specific crash locations. A systemic improvement is widely implemented based on high-risk unsignalized intersection features that correlate with particular crash types, rather than with location-based crash frequency (see safety.fhwa.dot.gov/systemic/index.htm).

Safety countermeasures should be implemented to:

  • Increase the visibility of intersections and traffic control devices
  • Increase awareness of intersections
  • Improve sight distance at intersections
  • Reduce conflicts by improving design
  • Improve intersection operation.

Extensive resources offer practical guidance for improving safety, mobility, and accessibility at unsignalized intersections. The Unsignalized Intersection Improvement Guide is a web-based program that guides users through the process of evaluating unsignalized intersections and identifying opportunities to enhance their safety and operational performance (see www.ite.org/uiig/process.asp).

The realization of the enormous growth of the highway industry in the mid- 20th century, in particular, the inauguration and implementation of the National System of Interstate and Defense Highway Act of 1956, and the recognition that the knowledge for such a program could only be consummated by the whole-hearted and integrated efforts of all persons associated with the highway industry, led to the formation of the American Society of Highway Engineers, with the intent and determination to assume it responsibility for the development of the rapid growing demands of the highway industry.

The Society was incorporated in the Commonwealth of Pennsylvania in 1958 with the conception and inception of the first Chartered Section (Harrisburg Section) credited to a small group of dedicated engineers from the Pennsylvania Department of Highways, in association with a group of outstanding contractors, material suppliers, and consulting engineers in the Harrisburg area.

Both the National and Section Board of Directors consists of representatives of contractors, consulting engineers, government agencies, materials producers, utility companies, and other highway related agencies being duly elected Officers to serve the Society.

MEMBERSHIP (Presently 6,000+ Nationwide)
Being desirous of offering participation at all levels of responsibility, membership is available to everyone in the highway industry. Individuals who have practiced or are now practicing in the highway industry are welcome to become a member of our organization.

The many and diverse benefits of a mutual desire among the members to cooperatively approach and solve the common concerns that must be faced has become manifest. The direction of the Society is presented by the goals in the Strategic Plan. The spirit of professional and personal fellowship has added to the strength of all.

Professional Development

ASHE Sponsored Professional Development is offered by the ASHE Harrisburg Section for a very reasonable site connection fee. Please follow the link below to access the course listings and sign-up.
