Driving Directions

GeoBase has a fully featured routing engine that includes:

  • Natural language directions
  • Obeys all rules of the road
  • Route highlighting
  • Point-to-point and multipoint
  • Fastest and shortest route
  • Multi-stop optimization
  • Highway or surface streets preference
  • Boundary avoids
  • Support for external routing strategies
  • Travel matrix function for use in enterprise optimization packages

Benchmarking with GeoBase has provided superior performance to other solutions available on the market.

Routes with multiple points typically have many possible paths, but only one will be the shortest or fastest. The Route class can determine an optimum path and re-order stops according to the routing strategy, including distance minimization and time minimization. Strategies may take into account additional variables such as toll roads, and are also utilized when calculating directions. Additional strategies can be implemented based on any parameter of the underlying data set such as, “allow buses and taxis or favor surface streets.” Individual street links can be weighted to respect dynamic elements such as road closures, traffic flow and inclement weather.

Custom routing strategies
 The GeoBase file system retains all of the underlying map data.  The routing engine supports custom routing strategies that incorporate additional restrictions or other flags in the routing algorithm.
