Traffic Impact Management Data

The Traffic Impact Management Data structure is a database table design which can be used to manage and publish Traffic Impact data.

Traffic Impacts include, but are not limited to, road construction, maintenance, road closures, detours, large traffic generating events, parades, dedicated haul routes. The data structure is flexible in that an entire construction project can be described simply with one record or, if necessary, broken into detailed traffic impacts (sub stages or closures with specific time windows). The data structure allows one or more impact locations and/or support route locations per traffic impact. This provides a means to track the traffic impact location as well as the related detours or key routes locations that will be affected by diverting traffic during the impact.

The Traffic Impact Management Demo (pdf) provides a brief overview of traffic impacts and how they can be managed using this data structure.

The Traffic Impact Management Data Description (pdf) document describes the data tables, fields, and values.

The Traffic Impact Management Data Exmaples (pdf) document gives an example of one traffic impact's records using the data structure including an index map showing the geometry locations.

It is intended that this data structure cover most, if not all, of an agency's traffic impact management business process needs including efficient collaboration and successfull coordination of area impacts with neighboring agencies.

There is a spatial component to the table design so it is recommended that an agency work together with their GIS experts when considering and using this solution.
