BEST PRACTICE:

K1−1: Work Zone Crash Data Analysis

DESCRIPTION:

In coordination with other sections within the Wyoming Department of Transportation (WYDOT), the Wyoming State Traffic Engineer monitors construction related accidents, analyzes the data, and submits an annual report to the State Construction Engineer. Data collected includes the number of crashes that occur in the following situations:
• Detour or lane transition;
• While flagging is present;
• Involving a traffic control device;
• Involving contractor equipment;
• Resulting in injuries:
• Resulting in fatalities;
• In an urban area;
• In a rural area;
• During the day; and
• During the night.

REASON(S) FOR ADOPTING:

The intent of this analysis is to correct problems with accident locations as they develop and to determine accident trends and the relationship between various methods of traffic control and crashes.

PRIMARY BENEFIT(S):

Safety issues can be addressed on current work zones, and corrective actions (such as revising traffic control standards) for future work zones can be taken to address recurring observations. These actions could involve situations in planning, pre−construction, construction, and maintenance.

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

This practice/policy is applicable for all work zones.
