Work Zone Data Initiative Activity Update

The Work Zone Data Initiative (WZDI) was created to gather best practices, educate practitioners, and move everyone to more standardized methods of data collection and analysis for work zones. This has included the development of a data dictionary, standard data elements and formats, and much more. The FHWA Work Zone Management Program recently published their quarterly newsletter detailing the progress made in this area. Learn more HERE.

This report was produced by Jerry Ullman and Melisa Finley of TTI. It looks at the benefits we can expect from more consistent data collection. In particular, local and state agencies, private data consumers, and contractors will all be able to compare projects, work zone impact mitigation strategies, and work zone design to find the safest, most efficient methods in any given situation. The benefits will be significant.

But there are many challenges as well. Currently work zone data collection in inconsistent due both to varying practices from one agency to the next and to a lack of funding. Getting to the point where everyone collects data on all work zones and in the same format will be a formidable undertaking.

And the richness of the data will make it even more complex. Consider the proposed elements for just this one item:

This will not be easy. But the rewards in reduced crashes and improved operational efficiency demand that we move forward. Perhaps we might start with a few “standard” elements such as location, dates, and measures of the temporary reductions in capacity as a way of demonstrating what can be done. Once consumers of this data get a taste, they will demand additional elements. And it will then be much easier to cost justify the effort.
