Plan Around Next Month's Closure, Not Today's
Every traffic API on the market answers the same question: what is closed right now? That question is worth answering. It is also the wrong one for most of the decisions a planner actually makes. The oversize load ships in three weeks. The seasonal lane is being quoted for August. The construction crew is scheduling a detour route for a job that starts after Labor Day. Nobody planning that work…
When planning for upcoming construction work, it is essential to focus on the future rather than the current state of traffic. Most traffic APIs are designed to provide information about closures that are happening right now, but this information is not helpful for long-term planning. The planned work that will occur in the future comes from the agency's project pipeline, which includes capital programs, STIP project lists, and upcoming closures pages.
This data is published months before any construction begins and includes estimated start and end dates, as well as the projected scope of the work.
Road511 normalizes planned-construction records from nine states and provinces into a single future_construction feature type, which contains 2,161 projects as of today. Each project has a projected start and end date, but these dates are estimates and can change. Virginia's upcoming-closures layer contains the most detailed information, with 927 records.
However, other jurisdictions such as West Virginia, Manitoba, Newfoundland, Nevada, and Prince Edward Island also publish planned work, but the information is not always easy to access or query.
To effectively plan for future construction work, planners should focus on querying the available data rather than relying on static reports. The /features endpoint can be used to query for future construction work along a specific corridor during a specific time period. By using filters such as starts_after and ends_before, planners can retrieve all projects that will be in the way during the desired timeframe, regardless of whether the start or end dates have been published.
Projects with known start dates but no end dates are treated as open-ended, while projects with no dates at all are excluded from the query results.
It is essential to recognize that planned start dates are forecasts, and forecasts can change. Any planner should be prepared for the possibility that estimated start times may slip. By using the /features endpoint with the appropriate filters, planners can obtain a comprehensive and up-to-date list of planned construction work along a specific corridor, enabling more accurate long-term planning.
