BEST PRACTICE:

K1-4: Work Zone Intrusion Reporting

DESCRIPTION:

The Minnesota Department of Transportation (MnDOT) initiated an independent study to learn more about best practices for reporting and documenting vehicle intrusions into the work space of a work zone including “near misses” that do not result in crashes. To support this effort, a survey of State departments of transportation (DOT) was conducted to learn about peer practices for work zone intrusion data collection. This survey was supplemented by follow-up interviews with survey respondents and a literature review that gathered information on work zone data collection practices.

REASON(S) FOR ADOPTING:

The purpose of the study was to determine what data other States collect about vehicle intrusions and what technologies are used in gathering and reporting the data.

PRIMARY BENEFIT(S):

From the three States that responded, MnDOT found that work zone intrusion data was typically collected via electronic PDF forms . The information collected included incident location, diagrams, accident history, and resulting actions. The survey information offers helpful insights for other States that are considering collecting, reporting, and documenting data on vehicle intrusions into work zones.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

All work zone related projects.

STATE(S) WHERE USED:

Iowa, Minnesota, North Dakota, Pennsylvania
