    How Drivetimes are calculated

    Does anyone know the actual algorithm tha MapPoint uses? I have a VB application, but on some addresses it is unable to calculate a drivetime zone. On other occassions it is wrong in spots.

    Thanks

    Hi,

    Are you sure that the point where it does not calculate is on a digitized road ?

    I don't know if the road is digitized or not, being in a rural area I would think not. BUT, I can generate a drivetime zone at 6 minutes but not 5. Being a math major, I was curious if the algorithm has been published.

    I doubt it. These types of algorithms in this industry, tend to be published by academics and carefully guarded by companies! (a parallel with search engines comes to mind)
