Patent number: 9857191Abstract: Systems and methods for determination of an access path are disclosed. The access path may include any drivable route that is within a site, and is often, but not necessarily, exclusive of roads in a road network external to the site. In some cases, access paths may include a set of streets between two or more sites without necessarily including a drivable path within a site. Further, the systems and methods may calculate or determine minimum cost routes that include the access path. In some cases, the calculated route may be the minimum cost route that includes the access path, but not necessarily a minimum cost route to a site. In other words, in some cases, the selection of an access path serves as a constraint that supersedes the calculation of a minimum cost route.Type: GrantFiled: March 15, 2016Date of Patent: January 2, 2018Assignee: Telogis, Inc.Inventors: Ralph Mason, Mark Fryer, Michael Fried, Jeffrey Fiore, Rick Turek, Brad Llewellyn, Peter Lear, Victor Rehorst, Steven Ashley, Ben Burns
