Method, apparatus, and system for automatic evaluation of road closure reports
First Claim
1. A computer-implemented method for automatically evaluating a road closure report comprising:
- processing, by a processor, the road closure report to determine one or more road links that are associated with a road closure;
constructing, by a processor, a closure link graph comprising the one or more road links, one or more upstream road links relative to the one or more road links, and one or more downstream road links relative to the one or more road links, wherein the one or more upstream road links and the one or more downstream road links are open for travel;
collecting, by a processor, probe data from one or more sensors of one or more vehicles traveling on a plurality of roadways corresponding to the closure link graph;
processing, by a processor, the probe data to calculate one or more vehicle paths traversing the closure link graph; and
classifying, by a processor, a closure status of the one or more road links based on the one or more vehicle paths.

Abstract
An approach is provided for automatically evaluating a road closure report (e.g., to reject or confirm the report). The approach, for example, involves processing the road closure report to determine one or more road links that are associated with a road closure. The approach also involves constructing a closure link graph comprising the road links, upstream road links, and downstream road links relative. The upstream and downstream road links are open for travel. The approach further involves retrieving probe data collected from vehicles traveling on roadways corresponding to the closure link graph. The approach further involves processing the probe data to calculate vehicle paths traversing the closure link graph. The approach then involves classifying a closure status of the road links based on the vehicle paths.
